The fishermen here will often catch lobsters in the waters around the island, both the Panulirus ornatus and the Panulirus homarus.  

Any photos of your crops? How much are you wholesaling your lobster for these days?

   The last couple of days I have been cutting lengths of bamboo to build a floating lobster grow-out platform which will house a 6meter x 6meter x 2meter net enclosure which will have bamboo walkways surrounding the new enclosure. With luck it will be completed in the next three weeks, and I will be making a Youtube video of this project showing from from beginning thru completion. which I will add to the thread once completed. 0.png.2e2b484b3ff08319160c3e5df30851fa.png

   I have nothing in the Dinagat Island nets right now. There were lobster buyers here yesterday. We allow them to setup in one of our bungalows as it is convenient for our neighbors to have to buyers come here, rather then the lobster farmers to have to travel to the city. We only charge the buyers 100php for the bungalow and they generally there for half a day every 2-3 weeks.

   The price of course fluctuate but as of yesterday morning 

Sub-adults 500gram to 700gram ----------- 3,200php (per kilo)

       Adults 700gram to 1,000grams ------- 3,400php (per kilo)

       Adults above 1,000grams ---------------- 3,600php (per Kilo)

Note: (1 kilogram = 1,000grams)

   I received a PM from a forum member that asked me two questions. What is the difference between aquaculture and mariculture? And why are so many photos missing from the thread?

   Well as to the first question aquaculture is the rearing of aquatic species primarily for a market. Take a goldfish for example, if you raise goldfish as a hobby your a goldfish enthusiast who decides to breed goldfish and raise them to sell to other goldfish enthusiast, you are just still a goldfish enthusiast whose hobby got a little out of hand but you are doing aquaculture. And if you buy goldfish fingerlings and raise them to adult size then you are probably a pet store owner who really sucks at selling goldfish fingerlings, but it is still aquaculture..  .

  Now when dealing with a market fish like catfish if you are breeding them in a hatchery and rearing them to market size that is aquaculture, or if you are buying catfish fingerlings and then raising them to market size that is also aquaculture.

   But when dealing with saltwater market species this is different: if you are breeding milkfish in a hatchery this is referred to as mariculture, and if you purchase milkfish fingerlings and then raise them to market price this is aquaculture. So a lobster hatchery is mariculture, where as a freshwater cray hatchery is aquaculture. This is why I use the term mariculture when discussing the lobster hatchery, and why I use the term aquaculture when discussing lobster 'grow-out'. 

   Now as to the missing photos there is nothing I can do about that. I would have to completely restart the whole thread from the very beginning which would merely be an exercise in futility, as later photos will most likely begin to disappear from the replacement thread. Sorry this is simply beyond my control but I am looking for a more viable solution to remedy this issue.  :biggrin_01:.

For over two decades the Philippine lobster 'grow-out' aquacultural industry has a annual 5% growth rate. I have been contacted by quite a few buyers asking when we will have product, and I am located in the very heart of the Caraga/Dinagat Islands lobster industry. The local demand will probably always exceed my supply., no mater much I ramp up my production. The natural seed supply restricts the growth of the industry as the availability of pueruli and juveniles really occurs from March thru August which is the peak collection season. The advantage with the hatchery is I will start off producing 3 brood crops a year only housing 3 females and 2 males. By adding additional breeder pairs and adding additional 'grow-out' larval pots and pueruli 'grow-out' holding trays production could increase to 12 brood crops yearly.

   One single 2 year old female 'P. 'ornatus'' weighing 1.2 kilos in 2002 housed in a NZ hatchery was documented to have bred 3 times in one year releasing a total of 1.6 million eggs of which over 1.2 hatched.  This means I can have a continuous regular supply of pueruli and juveniles even live-releasing upwards of 60% of my total yearly output back into the wild.  I simply will not have to room to house them.

How would I attach a 24 page PDF to this thread? It is the Feasibility Study for this hatchery project which I put together for the  Department of Fisheries.

   This is the final draft of the 22 page Feasibility Study which I wrote for the Department of Fisheries. There is quite a bit of information on the hatchery project and the island layout, as well as the Philippine 'grow-out' aquacultural industry. Perhaps some of the readers may find this information of interest.

I decided to split this thread because of the next three projects I am working presently working on. These projects are a bamboo floating lobster 'grow-out' net which will be the first of several that I will probably be constructing this year. A prototype PVC floating pueruli/juvenile 'grow-out' net cage which will be the first of many which will be used in the saltwater pond behind the facility. And three types of pueruli trap setups used to live-capture seed stock (fingerlings).

   This should allow the photos, videos and written information to be better organized while helping to avoid the subjects from overlapping, this is to make the different topics easier to be followed rather than being scattered among the information contained in this thread. This will also allow the information pertaining directly to the lobster hatchery project to be easier followed once the construction starts back up in the next couple of months. Then there will be multiple projects being worked on at the same time for the next two to three years, which certainly clutter the thread and make the information which will be discussed in the new thread to be hard to follow.

Hello Sir James 

Would you know where to buy lobster fingerlings? My aunt actually purchase 83 fingerlings last week in Surigao, I wonder if it is possible to import fingerlings from other country? Please advise? Or is it risky? TIA

Hello Sir James

   I myself will be looking for fingerlings myself as soon as I finish the floating net platform I am presently building here. The bamboo frame is almost finished and should be completed later this week. I will then probably travel up to Cebu to purchase the rolls of netting which will be sewed together. With luck I will have the project completed and anchored in place by the end of the month. Then I will begin to start devoting the time to network for lobster fingerlings and with luck this will be the last time I will be purchasing fingerlings for my own nets. I have been collecting the needed bamboo and materials to make my own traps to catch pueruli and juveniles as my farm on Dinagat Island is within a short walking distance of a known hot-spot for lobster fingerling collection. So with luck by the end of May I should be setting out our own pueruli traps. I had mentioned earlier on the thread That I intended on splitting this thread, which I will do later today. The two spin-off threads will be covering the construction of a floating lobster net system, and the second thread will be covering the lobster fingerling 9live-capture) traps which I will immediately begin constructing once the floating net platform is launched. Both of these new threads will delve deep into the subjects and will contain step-by-step details on how they are constructed.

   Lobster fingerlings is a rather broad term which encompasses five distinctive developmental stages. The first four stages are the non-feeding phases referred to as {Puerulus (singular) Pueruli (plural)} called Planktonic-Pueruli, Clear-Pueruli, H-Phase Pueruli and Pigment-Pueruli. Once Pueruli have developed through all four of these phases they will Instar (morph) into Algal-Juveniles. During this Instar (morph) 40%-60% of these Pueruli will die, even if properly handled during transport. The price of Pueruli can range from 90php-250php (per piece). If improperly handled it is not uncommon to experience mortality rates exceeding 80%.

   Young Alga-Juvenile stage which are 5-7gram dry weight size endure long transport (distances in excess of 12 hours with far more success. Algal-Juveniles of this size, if properly handed, generally have a mortality which is less than 10% due to transport. Of the 90% which survive, historically 90% will survive to reach the 500gram buyer's market weight. The price of young Algal-juveniles cost 350php or more.

   As to your question about shipping fingerlings to or from other countries? Very difficult and for two reasons. 1) the obtaining the required documentation need transport live fingerlings; most countries have quarantine issues making it almost impossible for an individual or small company to secure the documents and certifications. 2.) is a combination of fragile physiology and the complications of long air transport. At any point in the chain of transport there is an untimely delay, improperly handling or mechanical malfunction of portable aerators, depletion of dissolved oxygen levels, excessive CO2 level buildup or excessive rise in water temperature; then you risk the mortality of all the individuals being shipped.

   One also needs to understand that there are in fact 8 different primary species of Panulirus lobsters which are naturally found in the waters here in the Philippines. These eight species are the Panulirus homarus (Scalloped or Cancer homarus), Panulirus japonicas (Japanese Spiny), Panulirus longipes (Long-legged Spiny), Panulirus ornatus (Tiger, Ornate Spiny or Tropical Rock), Panulirus penicillatus (Grey Cray), Panulirus polyphagus (Mud Spiny), Panulirus stimpsoni (Chinese Spiny), and the Panulirus versicolor (Bamboo or Painted Spiny). The species I specialize in is the Panulirus ornatus (Tiger) as it grows the fastest, largest and brings the highest prices in the markets of China, Hong Kong, Singapore, S. Korea and Japan.

James, a side note to the lobster business I noticed in the news the price of lobster has skyrocketed on the east coast of the US.  Enjoying your posts, thanks.

   The prices are definitely a supply and demand market for the growers. During the off seasons when lobster fishing is restricted or limited the prices skyrocket. In Hong Kong and China the prices for Panulirus ornatus (Tiger' Rock lobster) has exceeded $140 per kilo. If you have ever eaten the lobster tail at a 'Red Lobster' restaurant than the odds were that tail was a 'Tiger' rock lobster.
