To examine the variation of multiple predator effects and functional response caused by interaction of conspecific predators under different prey density, we established swimming crab, Portunus trituberculatus - Manila clam, Ruditapes philippinarum foraging systems in the laboratory. Specifically,...

Shrimp farming in earthen pond is one of the largest seafood growing industries among coastal mariculture, but it has faced environmental issues in recent years, e.g. overloading of supplementary feed cause deterioration of pond environments. In order to assess the impact of pond shrimp farming...

The effects of different fattening diet combinations on the growth, nutritional value, and flavor of Eriocheir sinensis were compared. Four different fattening diet combinations were evaluated: A1, consisting of 80% iced trash fish (ITF) + 20% formulated diet (FD); A2, consisting of 80% ITF + 20%...

Mudflat shellfish have evolved well-adapted strategies for coping with dynamic environmental fluxes and stressful conditions, including oxygen availability. The Manila clams Ruditapes philippinarum are worldwide cultured shellfish in marine intertidal zone, which usually encounter great risk of...

Because the number of mislabelled seafood products in the globalised market is increasing, there is a need for additional effective technologies to trace the origin of these products. Several issues need to be clarified regarding the δ¹³C and δ¹⁵N analyses used to trace seafood products in order to ...

Marking technology is essential to evaluate the growth performance of shellfish species in aquaculture. Some fluorochromes have been widely used in shellfish growth studies, but their marking quality remains unresolved. In order to establish an effective marking technology in bivalves, three...

Oysters are a keystone species in estuaries and intertidal zones and have important economic and ecological significance; however, worldwide, the dominant aquaculture oyster species suffers from mass mortality owing to anthropogenic impacts and rapid climate change. As a possible solution,...

Microorganisms, as integral components of food webs, play key roles in regulating the aquatic environment in shrimp farming. However, the abundance and functional diversity of bacteria in shrimp aquaculture ponds and the factors shaping their distribution patterns remain largely unknown. We...

The Ostreid herpesvirus 1 (OsHV-1) is a lethal pathogen of the Pacific oyster (Crassostrea gigas), an important aquaculture species. To understand the genetic architecture of the defense against the pathogen, we studied genomic variations associated with herpesvirus-caused mortalities by pooled...

Two approaches (i.e. water and dry or semi-dry transport) have been developed for the transport of swimming crabs Portunus trituberculatus in recent years. To evaluate their differential effects on physiological responses of crabs, we measured haemolymph components (metabolic substrates,...
