Commercial catfish feeds contain a mixture of feedstuffs and vitamin and mineral premixes that provide the right essential nutrients as well as the energy necessary to use the nutrients. 2. While Rahmawati [5] reported the optimum dosage of Caulerpa lentillifera meal in tiger shrimp feed (Penaeus monodon) was 30g.Kg -1 of feed. To produce extruded feed, super micro-grinding equipment with above 80% 80 mesh need to be employed to produce perfect extruded feed. The composition of feeds is presented in Table 1. Generally the compound feed of Tilapia are in two types: pelleted feed and extruded feed. million fingerlings (MIDEM, 2014).

Feed conversion efficiency increased from 20% to 30% dietary protein, and thereafter decreased for diets containing 40% and 50% protein.The protein efficiency ratio for fry and young tilapia decreased with increasing dietary protein levels. To produce pelleted feed, the conditioning temperature should be controlled between 80-95℃. - often difficult to get adequate numbers of predator fingerlings 7. absence of pelleting machine, feed maybe prepared in this manner. What do fish need in their feed? Compound feed is widely applied in Tilapia farming in the world. In high temperature season, feed with high protein content is disadvantageous to fish digestion, resulting in fish disease. replaced for rice bran as carbohydrate sour, effect on tilapia. Adjust the pellet size based on fish growth rate and fish size. From the above, fish feeding is obligated to keep the rules: fixed time, fixed place, fixed quality and fixed quantity, and also consider these four factors: season, weather, water quality and feed eating situation.

Studies on some aspects of tilapia and feed formulation conducted at BRS are reviewed in this paper. There are different species of Tilapia in different growth periods, so their demands for feed nutrients will be slightly different. When the water temperature is below 15℃ or above 32℃, farmers also need to reduce feeding or stop feeding, which contributes to fish digestion, good water quality and feed cost controlling. The average number of spawnings and average number of eggs per spawning for fish receiving dietary protein levels of 25%, 30%, 35%, 40% and 45% were 8.0 ±1.6, 8.4 ± 2.2, 8.5 ± 2.7, 8.4 ± 2.5 and 9.4 ± 2.1 spawnings, and 1167 ± 305, 1082 ± 410, 1288 ± 324, 1145 ± 389 and 1328 ± 311 eggs per spawning, respectively.

We has been long dedicated to the quality manufacturing and credible trading of FISH FEED MAKING MACHINES. Weight the ingredients at the predetermined levels. Virtually identical spawning patterns were found in all treatments, but there was a great deal of variation in the frequency of spawning and egg production. They are easy to digest, and rich in lysine that plant feed lacks. In: FAO Fisheries and Aquaculture Department [online]. Fish were fed the control diet (Diet 1, Table 1) for 1 month as a conditioning period before starting the experiment. Food quantity to feed is 6%-8% of total fish weight. List of feed ingredients of plant origin (cereal grains and oil seeds) those are used or have the potential to be used as protein and/or energy supplement in tilapia feed (nutrient content in % dry matter) Table 11. Animal feed are mainly used as the raw materials of compound feed, not appropriate to use them alone as feed. Firew Admasu Hailu 1 *, Abebe Getahun 2 and Mulugeta Wakjira 3. Preparation of Roquette Seed Meal (RSM) and Feed Ingredients Analysis Please notice that above 50% cotton seed meal in fish feed formulation will influence Tilapia reproduction. With fish growing, food to feed will be gradually reduced to around 250g. Feeding rate also depends on fish eating. It would be Ok to use rice bran or wheat bran as feed. n this, we have selectively bred family pedigrees (now in 4th generation) with different susceptibilities as new models for our ongoing investigations.
