  1. Three years organizing facts and information, writing and revising script, creating drawings and diagrams, seeking and collecting photos, learning software and doing voiceovers; then 845 slides and an hour and 27 minutes flapping my later, and the first video of this 3-Part lobster tutorial is finally in the can and ready to view. Now I start on video two. Subscribe so you will be informed when the next video of this series is completed and uploaded, and share with others. Also may I give a warm Happy New Years from this little island paradise on the edge of a Surigao mangrove in the land of ''the Never-ending Summer''. Ahh it is a rough life, but someone has to endure it.
  2. For those who like watching videos of lobsters in a net as much as I like making them, then this new one is for you. This one is 'number 5' in an ongoing series, and I will try (providing the weather, electric company and internet all cooperate) add a new video every two weeks. I should finally finish and upload the first video of the 3-part Lobster 101 series in the next few weeks. This 3-part series has been a three year project requiring the collection and editing of over 800 slides, diagrams, drawings and photos. I also have had to learn the VirtualDub, ProShow, Open-Shot, Audacity and Ocenaudio programs to learn which worked best and could work together. The information for this project required the outlining of what became an 84 page voice-over script. I must apologize in advance for the voice-over work is primitive at best. All recorded using my Android cellphone, mostly while sitting outside in one of the bungalows or porch, always late night/early morning when most quite. Even then it still required constant stoppages due to passing fishing boats, barking dogs and karaoke squawking. The '101' 3-part video series covers the bulk of information I accumulated over the last nine years of personal research, pertaining to lobster aquaculture and the lobster aquaculture industry. I am safe in saying that it is extremely doubtful that you can find a collective wealth of useful information together in one source anywhere else on the internet. I know as it took me nine years and thousands of hours to collect what I am openly sharing to the viewers. So when the first video is released in the next few weeks, please excuse amateurish voice work. I am after all on a little 8 hector island on the edge of a deep-water mangrove, so it is the best this old Texas boy can provide. I will probably bore you all to sleep or to tears with my South Texas monotone voice, but the quality of the information, artwork and photos collected in this presentations should still make these three videos (when completed) a good watch.
  3. Thank you, and here is some additional information some may find useful. There is a buyer's industry here in the Philippines. There are a couple of local buyers who regularly travel to this small island and setup their scales and wait for the lobster farmers to bring their product to be weighed and sold. There are two buyer's prices: 500+ gram weight - Sub-adult size individuals @ 3,000php (per kilogram) 1,000+ gram weight - Adult size individuals @ 4,000php (per kilogram) Current approximate cost of Pueruli size individuals (fingerlings) -------- 200php - 350php (per individual) Current approximate cost of Algal-juvenile individuals (fingerlings) ----- 350php - 550php (per individual) Growth Weight Times: Individual Size to Market Weights Puerulus: to 500 gram ------------- (under) 10-12 months to 1,000 gram ---------- (under) 14-16 months Algal-juvenile: to 500 gram ------------- (under) 8-10 months to 1,000 gram ---------- (under) 12-14 months (With proper diet nutrition and feeding ratios)
  4. I had another 100 individuals delivered to the 'grow-out' net early yesterday morning, so I shot a short Youtube video showing the early stage Algal-juveniles being introduced to the net enclosure (lobster rain). This now brings the total number of individuals in the enclosure to 280 (algal-juveniles).
  5. This photo shows the complete frame with all the bracing. Moving the platform to the waters edge. As you can see the frame is light weight and very easy for two people to carry. The unit was set in the water and it was sufficiently buoyant and stable We still need to fabricate lightweight holding racks in the topsides of the outriggers. There will be four floating traps (two on each side) and transported to and from the locations were they will be deployed.
  6. The frame base needs length sections which will allow the plastic 5gal.''Jerry' cans to be sufficiently lashed to be bottom of the framework. This unit actually sits on 6 plastic cans (3 on the edge). Two shown in this photo are just being used while all the lashing are being completed. Photo of the lashings used.
  7. It took me a couple of months to find the species of bamboo I wanted to use to make the first four frames. This is a thick-walled dwarf bamboo species which will allow me to build a frame at a 3/4 scale. This will show a step by step walk-through of the construction of the frame of a Floating 'Light' Trap to be used to 'live-capture' lobster Pueruli. First cut the required bamboo lengths. Lay out the the first four lengths to form a square and lash together the corners. This photo shows the lashings. Then the five remaining bamboo lengths which will form the frame base are then placed and lashed together.
  8. I built one complete floating 'light' trap frame and but it through a lot of stress testing and I am quite pleased with the results.. I have three other frames constructed but have not lashed on the floats yet. This shows a top view as the units are lying on their side. This shows bottom view of the three same units lying on their side. and this photo shows the variety of dwarf bamboo used in the construction of these frames.
  9. Well although I have not updated this thread in a while I was working on the project. I was primarily focused on the floating platform which is the subject of another form thread. And I building a small lobster hut close to this facility so my wife can raise lobster individuals of her own. We have two other lobster huts in the waters around Dinaget Island. Well the floating platform is completed enough that there are 180 Algal-juveniles in the net, and the Lobster Hut is finished and the wife has 50 algal-juveniles of her own in her net. So it has been a productive four months since I last spoke with readers on this thread. So let me get you up to speed. I believe I mentioned that I planned to try to get everything together so I could start trying to catch live Pueruli and Algal- juveniles. And I bet most reader just said, ''You want to catch what"? So let me show you what the heck I am talking about. These little delectable sea-bugs are Pueruli (plural term) the singular term is a Puerulus. There are four developmental stages for Pueruli but the first occurs out on the edge of the Continental shelf, they Instar (moult) and transition to a clear little critter called a post-phyllosoma Panktonic-puerulus (stage 1). This stage will have developed to a (stage 2) Clear-puerulus by the she reaches the coastal coral/grass zones, and will be the smallest size Puerulus you will live-capture. Then over the next 4-5 weeks she will transition through the (stage 3) H-puerulus and the (stage 4) Pigment-puerulus. This is when for the first time they look like little facsimiles of their parents and is the first many of the 22 species of Panulirus lobsters can be properly identified, others will still need to transition to Algal-juveniles before reliable identification is possible due to lack of distinguishable markings. Once (stage 4) Pigment-puerulus reaches their latent stage they face an Instar (moult) which naturally has a 40%-60% mortality. But those that survive this Instar (moult) will have transitioned to the Algal-juvenile developmental stage. Most of the seedstock sold to local lobster farmers for their 'grow-out nets are Pueruli because they see them as being cheaper to purchase. The price for a (stage 2) Clear-puerulus just three years ago was 90php but today ranges from 200php - 250php, and the price for a (stage 3) H-puerulus or (stage 4) Pigment-puerulus now sell for 250php - 350php each. And still 40%-60% of those will die, more if they are mishandled before being delivered to the lobster farmer. I have personally know buyers who lost more than 80% of their Pueruli within three weeks after they were delivered. Once (stage4) Pigment-pueruli successfully moult to Algal-juveniles those prices double, because those within the industry know that more than 90% of Algal-juveniles will survive to reach the (500 gram) buyer's weight. Presently a the (500+ gram) buyer's price is 3,000php (per kilogram), and at the right time of the season the (1,000+ gram) buyer's price id 4,000php (per kilogram). If one specializes in the 'live-capture' of Pueruli and Algal-juveniles it can be quite profitable as a stand-alone venture. If in combination with the ability to also use 'grow-out' aquaculture to successfully raise the seedstock you caught to market weights you can generate exceptional profits. If you are in the right general locations.
  10. With floating nets they require sag-weights suspended from the bottom edge of the netting to help prevent the netting to sag in the middle like a big wet sock. The bigger the net, the bigger the problem. This issue is compounded in seawater due to tidal currents. In ponds and lakes there are winds and wave-action but minimum currents. If one uses floating cages in rivers and streams currents are an issue which is drag. Large surfaces no mater now light create drag, and the larger the surface the larger the drag. Any cubed ring around the bottom of a net, despite material type, will create drag forces. A few rope lines and small bags of rocks have a minimum drag. This is a diagram showing the rope and weight configuration. As you can see this is an excellent light weight solution with a minimum current drag. It also removes the weight of the sag-weights on the ropes suspended to the under-frame of the platform, removing the weight off the 'grow-out' net. The bottom of the net area sits directly on the support ropes, and the weight placed on the bottom is distributed into 16 smaller surfaces instead of just one large surface area. This is important with a net this size as it will house hundreds of Adult lobster easily weighing a kilo each, which are free-roaming over the bottom of the enclosure.
  11. The 'Tiger' lobster are tasty little sea-bugs, but at 3,000php they are expensive critters . We have a 600 meter net which gets dropped in the water just offshore here, when the wind and water conditions are right. In the last 4 weeks we caught two mature 'Tiger' lobsters (800 gram) and (900 gram) in that net. This is the (900 gram) critter pictured here. but the net has also yielded a few few (eaten size) of another type of tasty lobster. This little jewel is a Thenus orientalis (Brown Slipper Lobster) and I find to be as tasty or even more tasty than the 'Tiger' lobster, and these we get to actually eat. I ate my Tigers when raising them as a mere hobby, but now they are a business and one should never eat their profits. this is what their underside looks like. I am actually thinking of also trying to raise these from eggs. They have a considerably shorter larval period and they can grow to a weight of 2 kilogram and they are tasty. Their diets are similar and can be raised on the same platforms just in separate nets. These little bad boys were caught within 200 meters of this island are 'Mantis shrimp' the Filipinos call them tatampal, hipong-dapa or alupihang-dagat and a whole host of really bad words if the careless when handling these little tasty thumb-spliters can not be held enclosed in 'grow-out' nets because they can literally slice through the netting and escape. So it will be a while before I can build a few tanks on a separate 'closed-circulation system, perhaps in a few years from now. I have yet tried eating one of these sea-bugs, so I can not tell you from personal experience what they actually taste like, but the locals love them and they sell for 1,200php per kilo here locally. But since shrimp and crabs are abundant here I have then in my diet quite often. I love living in this area of Northern Mindanao...
  12. How many rednecks would live to have a piece of yard-art like that just outside their front door? Well it was time to start lashing down the large 'grow-out' net. For readers who have interest in building their own floating nets there is something you need to know. Currents and wave-action will cause a net to sway from side-to-side and nets will naturally sag in the middle making your square net akin to a limp cock. This opens all kinds of issues you want to avoid. The solution is easy if it is done right, but many sources (drawings) show a pretty picture but are made by people who actually do not have a clue about nets. A prime example is this drawing found in the internet. One is the placement of barrows as they need to be elevated if you notice I use elevated supports to raise the frame much higher. This helps compensate for the (wet) weight of the netting and lifts the frame higher above the wave-action. This helps moderate waves from washing over the top of the walkway decking which can cause structural damage. The drawing also minimizes the need for strong top-rail to raise the sides of the net. During storms lobster will actually climb up to the edge of the water line, which means if waves are washing over your walkways and slamming into your nets. There is a reasonable possibility the net poles will quickly fail. And if that happens those clever little sea bugs will be surfing those waves to freedom. Also and more important they imply attaching sag-weights directly to the bottom of the net edges which increase the chance of rips and tears in the netting. This is because wave action will cause those sag-weights to erratically sway and pop against netting. The next drawing is my own and shows the proper way to attach sag-weights. The sag-weights are not connected directly to the bottom edge of the netting. Instead the sag-weight is extended by a line attached to platform frame, slightly wider than the bottom if the netting. This slight tugs the bottom straight and flat. What the drawing does not show is that under the net there are cords are also tied to the saw-weight which is directly across from it. This creates a cris-crossing of support lines adding support to the net floor which helps prevent the net from excessive sagging. If you have several hundred individuals as weight 500-grams each then net-sag can really be an issue. Here the main 'grow-out' net was being lashed down and the sag-weight lines were being tied to the bottom of the platform frame at the same time. The sag-weights are just a lighter version of the anchor weights, each sag-weight weighing approximately 10-13 kilograms. This Youtube video of mine clearly shows the sag-weighs and anchor lined under the water-line.
  13. Well at the point of this posting I had more bamboo delivered, cut and temporarily lashed as decking, unfortunately we have only found enough to complete two sides of the walkway but it is still enough to do the trick. We pulled the platform approximately 12-15 meters out from the shore directly across from our front gate and tied a mooring rope to a coconut tree. We used doubled-rice sacks as anchors, 5 sacks to an anchor line and one anchor line at each corner of the platform. This is to prevent the platform from twisting at low-tide during stormy weather. Using the mooring line to the tree also helped to maintain a prospective of 'square' when out in the boats trying to plumb the platform to the island. the current flows in opposite directions, determined by the tides, so the platform drifts. So it makes it more difficult using paddle boats to determine exactly where to drop the first two anchor lines. The mooring line is a huge help as the platform could be easily corrected by one boat while the other boat could drop the anchor lines. As you can clearly see the anchor line is far from being high-tech. You paddle out and push the rice sack out which is connected directly anchor line. These sacks are filled with rocks and cement chunks and weigh 70-90 (kilograms) each. Now it gets suffocated... A piece of rope is tied tightly around the neck of the sack, and tightly tied as to have a strong rope loop. Then a medium size stone is placed inside the neck and above the stone the sack is firmly tied. These typed of anchors then has the anchor line threaded through the loop, and then the sack is dropped into the water where it slides down the anchor line were it rests on the seafloor. Four of the type of anchors are used on all four corners of the platform. The whole process is really simple and new quality rice sacks are sold in most wet-markets. Double or triple the sacks so the will last.
  14. Algal-juveniles can be quite aggressive and prone to cannibalism which is why they must be removed from the first Nursery 'grow-out' net' and relocated to the secondary Nursery 'grow-out' net. Here inside this enclosure the young Algal-juveniles will remain and continue to develop. These individuals are simply too aggressive and cannibalistic to remain housed with the Pueruli stage individuals, but are simply too underdeveloped to be housed among the latent-juveniles, Sub-adults and Adults. They will remain in this enclosure until they have developed to 70-gram Post-algal size individuals where they will be relocated to the main 'grow-out' net enclosure. The large main 'grow-out' enclosure houses latent Post-algal, Late-juvenile, Sub-Adult, and Adult size individuals. As I mentioned earlier this large net can comfortably house 800 (1,000 gram) Adult size individuals, so when the time comes that the net capacity proves insufficient, I will have already built a second floating platform which will be used to house latent Sub-adults and Adult individuals. This photo shows the frame of the first Nursery 'grow-out' net and the netting being readied so it can be lashed to the PVC frame. If you look closely you will notice there is a divider as this is actually two nets in one. The pueruli are housed in the larger section. The second section is for latent Pigment-pueruli so they can be isolated before they Instar (moult) and transition to young Algal-juveniles. This isolation is for two reasons. 1.) is that after they successfully Instar (moult) their new exoskeleton is so soft that for the first 10 hours it will not the weight enough to stand. The exoskeleton will need 7-10 days to properly harden. During this time that can be adequately feed as they were previously in a non-feeding phase. 2.) if left among the Pueruli they would prey on the Pueruli, but if latent Pigment-pueruli are put in the second 'grow-out' net to moult they will quickly become prey themselves. This photo shows the size of the net Nursery 'grow-out' nets. My wife stands 5 foot so it is easy to gauge the dimensions of the net. And this is a photo of the first 'grow-out' net being readied to be towed to the Floating Platform. The two 'grow-out' nets float inside the main 'grow-out' net and held in place using a singe line of nylon cord. When not in use during they are simply removed, thoroughly cleaned and stored on-land and should provide many years of dependable service.
