Fish Feeds

 Fish Feed and Feeding 

One of the biggest challenge that our Kenya fish farmers are facing in aquaculture is the unavailability of efficient and affordable farm  made feeds designed for semi-intensive culture systems. These forces  most of our farmers to rely on natural food in the pond system with  some supplementary feeds to increase fish yields. Most of this supplements are cheap and readily available. Fish farmers have ready access  to different feedstuffs depending on their locality in the country. However a single ingredient for instance wheat brans is no sufficient and requires to be mixed with other ingredients to form a compound feed which is more effective for fish growth.  Small-holder fish farmers should utilize on locally available feedstuffs to feed fish in order to improve their profits.


Feed production

Feed Production usually includes a number of steps i.e. identification of    the feed ingredient and their ratios; mixing, grinding, binding together,   drying and packaging. Feed preparations are made using improvised machinery that are operated either manually or mechanically. Feed ingredients are weighed carefully as per the formulation and then mixed to ensure evenness. After mixing, feeds are made into pellets, dried and sealed in bags. 


There are three types of food used in aquaculture

1.     Natural foods occurs naturally in the fish ponds. This includes detritus, bacteria, planktons, worms, insects, snails, aquatic plants and fish. Their occurrence and abundance depends on the water quality and in particular fertilization.

2.      Supplementary feeds usually consists of cheap feeds materials availability locally such as terrestrial plants or agricultural by-products.

Many kinds of feed materials may be used supplementary feeds for your fish such as:

·         Terrestrial plants: grasses, leaves (e.g cassava) and seeds of leguminous shrub and tree vegetable;

·         Aquatic plants: water hyacinth, water lettuce, duckweed;

·         Small terrestrial animals: earthworms, termites, snails;

·         Aquatic plants: trash fish;

·         Rice: broken, bran hulls;

·         Wheat: middling, bran;

·         Maize: gluten feed, gluten meal;

·         Oil/cake after extraction of oil from seeds of mustard, coconut, ground nuts, cotton, sunflower, soybeans;

·         Cotton seeds;

·         Brewers wastes and yeast;

·         Slaughterhouse water: offal blood, rumen contents;

·         Manure: chicken droppings, pigs manure

3.     Complete feeds are made from a mixture of carefully selected ingredients to provide all the nutrients necessary for the fish to grow. They are made in a form which the fish find easy to eat and digest. These feeds are difficult to make on the farm and are usually expensive to buy. Under intensive systems, feed provided to the fish must meet all their dietary requirements. The fish rely wholly on exogenous feeds. The feeds must be complete in terms of nutrients supply.






AAK is the National umbrella body of all fish farmers in Kenya.It was formed to bring together all fish farmers in Kenya with the sole purpose of providing them with one voice on common issues affecting them.
