Good nutrition in fish farming production systems is indispensable to produce a healthy, high-quality product. Nowadays, the nutrition represents about 50% of production cost. So, it is high time to look for good nutrition that can satisfy the fish farming quality and at the same time is low cost. Therefore, my question is which is a suitable range for artificial diets for both either complete or supplemental for the following ingredients (protein, carbohydrates, fats, vitamins, and minerals) necessary for the optimal growth and health of the fish. Moreover, is there any international or national standard or specifications to prepare Good nutrition in fish farming production systems, any books, scientific papers and extension recommendation concerning these issues is required.
Dear Mohammed
There is not specific standard for proposed chemical composition of fish diets Processing .
Where diets composition differs with difference feeding to fish cultivated, whether marine or freshwater fish. warm water or cold water fish. fry or adult fish. Herbivorous or Carnivore.

Dear Nawras A Al-faiz
Thanks very much for contributing to enrich the discussion. So, to be more specific , I am looking for freshwater fish in warm water for small-scale farms for both fry and adult fish.
Feeds depend upon whether they are herbivorous or carnivorous. The the former feed pellets of quite smaller size made of cooked groundnut/soyabean oil cake mixed with rice bran can be used. For the latter even though the same can be used, but for better growth protein from animals like silkworm pupae, black soldier fly, & fishmeal made from trash fish can be used mixed with the plant component.
Looking for refereed journals that publish articles on decentralization
Dear professor Adam Mohamed
please send Email to in my account
I will reply to your question
Dear Mohammed,
I'm agree with my friends. First of all you most choose your fish species. Also you can find requirements of different fish species which are suitable in aquaculture in NRC (Natural Resources Council of America) tables.
First their are many Ref. about nutritional requirement of fish, second every species and stage for same species differ from other, so determine your species and stage and I will help you. Attached a useful book
Dear Mohammed,
In order to obtain a suitable answer, you should identify the following:
1- Fish species that you intend to culture.
2- Culture system.
3- Production goal.
4- Economical aspects of production.
Every combination of these factors will give you a different answer. Of course, you will find huge number of publications on this topic. The following link could be helpful.
Best regards

Dear Mohammed,
I agree with Dr. Najim, additionally you should also tell us whether you are going to raise larvae/fingerlings (young fish) or older fish (Larvae and Fingerlings need the feed with higher protein content than older fishes). In our fish farms feeds represent up to 70% of production costs. The Fish nutrition manual prepared by us is unfortunately available only in Russian language. For the balanced fish feed formulation you can use following very useful source (see attachment).
