The increasing growth of the bivalve-culture industry necessitates a scientific assessment of the carrying capacity (CC) of this aquaculture system, in order to ensure sustainability. Here, using a marine plankton ecological model and the food balance, bivalve CCs were estimated for aquaculture...

Predation, especially by crabs, is a common source of mortality for natural and farmed populations of intertidal clams. Consumption of juvenile "seed clams" forces aquaculturists to try to exclude predators and/or raise juveniles in hatcheries until they can reach a size refuge. We ran a variety of ...

Summer mortality is a phenomenon that causes mass die offs of molluscs during the summer months. Summer mortality affected molluscs include many economical important animals including; oysters, mussels, clams, scallops and abalone. The condition occurs in both natural and aquaculture environments...

The blue swimming crab, Portunus pelagicus, is a commercially important species of the tropical Indo-Pacific region which shows substantial potential as a candidate species for aquaculture. The complete cycle of blue swimming crab culture program (CBSC program) was an integrated research for...

Oyster recruitment to spat collectors can result in the clumping of two or more individuals, whereby they naturally cement to each other's shells. On-bottom oyster farmers typically separate these oysters and re-deploy them on the seafloor, potentially exposing them to predators. This raises the...

The French network REPAMO was created in 1992 and was in-charge of the surveillance and monitoring of the mollusc health along the French coast according to the European legislation. The missions of the network includes: surveillance of notifiable diseases present in France, study of abnormal...

Innate immunity is the only defense system for resistance against infections in crustaceans. In crustaceans, white spot diseases caused by white spot syndrome virus (WSSV) are a serious viral disease with high accumulative mortality after infection. Attachment and entry into cells have been known...

Aquaculture of portunid crabs is hindered by high mortality during larval rearing, which is often attributed to inadequate nutrition. Live feed enrichment and greenwater are techniques used to improve the nutritional quality of feeds for larval fish and some invertebrates, but their usefulness for ...

This work develops, applies, and tests a methodology for simulating three key determinants of aquaculture carrying capacity: production, environmental effects, and pathogen interactions. Deterministic models for simulation of biomass production and environmental effects for fish and shellfish were...
