Sir i came across this video of yours just by chance and must admit i have yet to have seen someone as passionate as u towards the explanation n examples to make lay people like me understand instantly. I will watch all ur videos for accumalating the profound knowledge u share. Thanku n Godbless
I'm also a Shrimp technician that is assigned in different shrimp farms here in the Philippines by a international feed company. This video helps me a lot especially this days when we have problem in our client's pond during their molting stage. I am planning to seek an opportunity soon overseas in this industry.
Dear Jose, thank you for your lovely videos. I am a novice where shrimp culture is concerned but I am passionate and have my own farm. I have been asking locals and watching videos to educate myself as much as I can. Though I face a new problem every time I will not loose hope. We have plastic lined ponds 1000sq meters with a 8inch central gravity drain. For aeration we have developed our own venturies that work very effectively at a depth of 6feet. I have no problems where aeration is concerned. #)Somehow I have been victim to white feaces in the last few crops. It throws the entire growth cycle for a toss. What precautionary measures can I take to avoid it and are there any home remedies I can apply (tamarind water mixed in feed ? Garlic mixed in feed ? Buttermilk in feed ? Some even say mangrove leaf reduction works well ?) #)About the moulting in lay man terms we see the moon cycle and expect a moulting or even if there is heavy water exchange. As you said we do reduce the feed but only around 10-20%. And as a lay man I would not understand what exact stage the moulting process is at. I would be greatful if you could explain it stage wise, what to expect what to see in the check trays etc. What to look for. Here we just press the shrimp and see if it's soft and if the thorn on the head bends it's moulted. #)Somehow my shrimp are moulting all the time. Because I give at least a 30%water exchange every week. I don't know when was the last time I saw a hard shrimp. Also if a shrimp moults in stress out of its regular cycle does it still grow ? If yes is controlled stress(sudden water exchange 30-40% advisable ?) I would be greatful if you can help me with my questions. Regards. Rohaan M

Question ：how do you know if the molting is in mass or partially by siphone ？ do we need to weight the molted skeleton in each day ？ do you have some kind of formula by comparison weight from skeleton molted and total quantity shrimp, master ？ i have a vannamei Shrimp pond in indonesia.
Hi Alex! 1st question, only by sampling about to 30 shrimp and following the protocol in the Molting video. 2and question, no not needed. 3red question, No I don't. Only way to figure out biomass is by amount of feed taken by shrimp. Kind regards and thanks for sharing
@@alexgunawan98 The most important is to be mindful not to waste feed ($) if there are molting, this is why we need to have feeding trays; and and also not to harvest if they have just molted.
Thank you for that informative video,im a shrimp technician and encounter lots of problem..i just want to ask if u can give me some advice for plankton die off,im applying probiotics but still the water is clear.thank you in advance
Hi, please tell us more about your pond and culture system so that we can advise on your specific case, the more information you can provide the better
Our pond using a liner, 25 days, from disposal of shirmp fry, in night time the water had to much bubbles, and water began color it red what are we going to do, in order our water back into green,
Hi Sin Gooi. I haven't used this particular system, just the ones I describe in my previous videos about soil and water preparation 1 and 2. Also see the intensive systems video.

Can we give minerals on all the feed cycle of shrimps pn a daily basis ( how many times) .Will this improve the health & survivability of shrimp against WSSV & white gut problem
Hi, if you use good quality feed and your water is balanced in terms of ions, there is no reason to give additional minerals. There is no evidence that shrimp benefits from added minerals. Depending what these minerals are, it can even be counter productive. There are specifically formulated feed additives like organic acids and probiotics that you rather use. But nothing replaces good ponds and water preparation, management, feeding, monitoring for good health.
If we are giving Lab grade mineral of Na, Mg & K mixing it with feed.. How much grams of minerals to be given to shrimps per day & what else minerals to be given to shrimps st what intervals
Hi , shrimp take these minerals from the water, there is no need to give in the feed. Just use good quality feed and check the ion levels in the water - if needed you need to add to the water.
Sir, I have a question. Possibly not all shrimp in a pond will molt at the same time so that it would be quite difficult to modify feeding regime followed the feed demand pattern as you showed. So my question is how to trigger a "healthy" massive molting in intensive shrimp ponds? Thank you so much in advanced.
We don't need to do that but if you need to transfer shrimp from a pond to another, or a final harvest where they need to be all hard you can induce them to molt all together
You 1) do a heavy water exchange of 50% or more, 2) apply 50 kg/ha of hydrated lime followed by 3) 25L/ha of H2O2 (35% strength). They will molt within 24h, then wait 3 days to harvest or transfer
Thanks for the information.. Can you please let us know that, is there any difference in check tray monitoring interval (2 hours) between natural pond and high intensive biofloc tank with a capacity of 3 lakh litres water and 150000 shrimps. I mean need we to check the Tray in 1 hour because there are more shrimps in lesser area..
Hi Fasal, firstly it is important to have a few trays per tank / pond for monitoring. About the timing, I would stick to checking after 2 hours. It is important not to change the time to check once you start.
Thanks Jose for the Infos. Questions: 1) do you will also explain about "blind feeding"? (Feed program during DOC 1-30) 2) Do we really need to give so many feed to the pond even still in PL stage? 3) any refenrence for feed program? Thanks for respond
Thank you very much for a very informative and well organized presentation.
You are welcome

Hi Jason, here to help. Best of luck! Please share the channel with your colleagues and friends please
Thanks for the well explained technology..
The best teacher. Thanku sir
You made my day 💕
Thx sir for the content and also for the information, today i learn something new on shrimp culture
So nice of you
Nice information.👍
Thanks.
Thanks from Indonesia
Thanks sir, it’s very informative session
Most welcome
Hi this is sunil
Ty for information
We attainted an FCR of .61 in 62 DOC - 12.49 Gm weight harvested 1230 kg feed used 761 Kg stocking 100000 pond size 1.1 acre
Great work, this is excepcional (= exception to the norm) , but over many ponds and cycles you can expect highest FCR
Can we give them commercial grade minerals ( MgCl , Ca & Potash ) to shrimps .or anything else

Thank you
Question : sir. .what make the shrims to move backward when we try to catch them or anything fall near them?
haha, the move like that as part of their "escape plan" - the predator thinks they can only move forward, but they are faster jumping backwards :)
Is it possible to give green water instead while they are molting?
how would you do that?
After just moulting what type of feed we have to gave to shrimp
the same shrimp feed as before, but note they won't eat until they harden again
Hi, the same feed, but just less

Dear Dr Jose. The AB, CD, EF stage i did not see in the graphs feed consumption vs molting stage. Kindly put in the graph. Thanks
