Hi Jose! Good morning. This is C. S. Roy from Kolkata, India. I'm going to have L Vannamei and P Monodon culture in 5 hectares water area. I gather knowledge and writing note in diary from different RUclips videos including yours. I really like your lecture. I would really be happy to get your support and suggestions during my culture period. Although I get most of my questions answered from your videos. Still if I need something more than how could I get you in touch. Please send me some guidance..
By profession I'm a teacher. Fish culture is my passion and I want to support my local farmers in this.
Thanks....

hi , i am a hongkong farmer who is farming shrimp in gd. It is hard to get sodium nitrate as it is not common fertilizer. Can i replace it with calcium nitrate , mg nitrate , K nitrate , Ammonium nitrate ? And will you talk more about the ion management of open pond biofloc system in future. thx

[@joseantoniosantosdom]

Hi Patrick, yes you can replace with othe Nitrate, probably not Ammonium Nitrate as it is explosive and highly regulated. Calcium Nitrate is good but mat come with 1% ammonia. K Nitrate a bit more expensive but good if you don't use seawater as K is limiting in inland waters. I can consult if you like. We are also planning a short course on shrimp if you are interested

[@patrickyeung9432]

​@@joseantoniosantosdom thank you very much. then i can use k nitrate as they need K in fresh water. and my experimental biofloc open pond is about 1700m2 with 1.7m depth
4ppt
unlined
a3 venturi injector with 4kw x 2 (x4 in future) under water pumps
18kw inverter for the pumps
planning of 300000 fast growing seeds
3m3 settling tank
1m3x2 em tanks
Do you have any suggestion on density , ion and management of these unlined pond? do i need extra shielding of sunlight ? will i have big problem with the unlined pond ?
