Ponds constructed where soils contain sulfides can have problems with low pH in culture water. Liming can be an effective emergency measure.
Based on thorough knowledge of the culture species, feed formulations must deliver protein and energy, and a balance of nutrients in a palatable form consumed with little waste.
Red abalone-breeding programs need to consider total weight rather than shell length when broodstock animals are selected.
Several trials in Ecuador and Thailand showed that nucleotide supplementation in feed can improve growth and survival in shrimp and tilapia production.
Molluscan seed production in China encompasses 32 species. The seeds of most clams are collected from natural sources in farming areas.
Shrimp diets need amino acid composition, balance and availability. Protein digestive capacity appears related to both nutrient availability and composition in feed.
Breeding research is pursuing a hardier hard clam strain to improve survival during Florida’s hot summers. Diversification would support additional growth.
Oyster farming in South Australia has become a highly productive and sustainable venture. A quality-control program, new grading systems and government support can help increase oyster exports.
Rendered animal proteins present viable alternatives to fishmeal in aquafeeds. High digestible protein and energy contents make them cost-efficient in low-fishmeal formulations.
It is important to understand the distribution of pathogenic bacteria in the marine environment to predict potential health concerns transmitted by seafood.
