Oyster output affected by environmental features of farm site
In southern Brazil, management data for Pacific cupped oyster culture were assessed to characterize production in relation to environmental parameters.
Responsibility
To support projected food demands, production must rise an estimated 70 percent above current values. Aquaculture can play a key role in raising food in limited space for feeding a growing population.

Aquafeeds
A recent study in Brazil tested the efficacy of nine commercial feed attractants for Litopenaeus vannamei. Condensed fish-soluble protein, an amino acid complex with digested bivalve mollusk, and whole squid protein hydrolysate stimulated the highest feeding responses.
Aquafeeds
In a study, the authors evaluated the stability of six commercial feeds under temperature and salinity conditions that occur at most shrimp farms in Brazil.
Health & Welfare
Shrimp diets need amino acid composition, balance and availability. Protein digestive capacity appears related to both nutrient availability and composition in feed.
