Feed Management to Improve Production and Profit

September 24, 2020

Feed management is a key factor that influences water quality and production economics in aquaculture. Survival and growth have the biggest impact on the economic performance of shrimp production, and to maintain both correct feedings is essential. Therefore feed management strategies should aim towards optimizing feed inputs, reducing feed conversion ratios, and reducing the potential effect on the aquaculture and effluent water. Environmental, social and economic considerations drive the need to improve feed management and Vannamei feed formulations.

If shrimp farmers want to run a profitable business they must improve economic efficiencies and they should set an image of a sustainable industry. Feed management is a poorly understood “art” because numerous factors affect not only growth but also the size of the population which is quite difficult to determine.

Irrespective of the methods employed, all feeding protocols should always include the following considerations –

  1. Feed utilization should be planned and daily feed inputs should be limited.
  2. Placing upper limits on daily feed inputs based on historical growth rates helps to limit expectations.
  3. In ponds without aeration process, suitable feeding rates have been found to be around 25-30 kg/ha/day. With night time mechanical aeration, feeding rates can be within a range of 100-120 kg/ha/day.
  4. Multiple daily feedings are recommendable because shrimp eat slowly and almost continuously.
  5. Per day six feedings did not improve growth hence, moderate feed input that is, 2-4 times /day (depending on the size of the shrimp) is often recommended.

Water temperatures and dissolved oxygen levels are primary factors that influence feeding activity, metabolism, and growth, and these factors are regulated by the types and quantities of feeds used.

A poor understanding of daily nutrient requirements coupled with the ultimate desire to obtain maximum growth farmers often overfeed the shrimps and have relatively poor FCR. Consequently, there is a high need for re-assessing current feeding protocols and to develop new feeding strategies. Nouriture has gone through a long research to develop high-quality Vannamei feeds that determine the lowest FCR and higher nourishment that maximizes the growth rate and profit. After all, we should count on the fact that Feeds can make the whole difference.
