Shrimp survival, weight, yield and feed conversion were better in farm units that operated with settling chambers for solids removal than in units without.

The authors conducted a study to determine how replacement of salmon meal with various animal protein meals in feed affected the growth performance of white shrimp.
In a 10-week study of nursery-reared Pacific white shrimp performance, the inclusion of Spirulina meal allowed reduction of fishmeal up to 25 percent with no detrimental effect on shrimp growth performance.
A study evaluated Pacific white shrimp given plant protein-based diets with varied lipid content and soybean meal:soy protein concentrate ratios.
Intensive nursery systems are an extension of hatcheries to acclimate postlarvae to farm conditions and assess quality and health prior to pond stocking.
Much of Brazil’s expanding tilapia aquaculture takes place in floating cages with sturdy frames and nets made from plastic-coated steel or polypropylene.
Due to its high protein and highly unsaturated fatty acids content, krill meal can be an effective ingredient in aquafeed.
The required level of fishmeal in white shrimp diets can be reduced to 5 percent through substitution as long as fish oil content is kept at 2 percent.
In a study, the authors evaluated the performance of juvenile white shrimp grown at high density and fed diets with varying levels of methionine. Trends toward improvements in feed intake were observed for diets with reduced fishmeal and HMTBa supplementation.
