The effects of size of Manila clam Ruditapes philippinarum on the predation rate, foraging time budget, encounter behavior and shell-breaking techniques of swimming crab Portunus trituberculatus were studied by video recording analysis system in the laboratory. Here, we report the differences...

Closed polyculture of penaeid shrimp (Penaeus chinensis), Taiwan red tilapia (Oreochromis mossambicus × O. niloticus) and molluscs (constricted tagelus (Sinonovacula constricta) and scallop (Argopecten irradians)) was studied from 1995 to 1997 with the enclosure experiment method. Four...

The functional diversity of flora was studied in four polyculture ecosystems including swimming crab Portunus trituberculatus, Chinese shrimp Fenneropenaeus chinensis and short-necked clam Ruditapes philippinarum (B), swimming crab, Pacific whiteleg shrimp Litopenaeus vannamei, and short-necked ...

The functional diversity (FD) of the microbial communities found in pond waters was examined with the BIOLOG method for five different aquaculture groups: (1) monoculture of crab Portunus trituberculatus, (C); (2) polyculture of crab and white shrimp Litopenaeus vannamei, (CS); (3) polyculture 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 ...

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,...

The rapid emergence of deep learning (DL) technology has resulted in its successful use in various fields, including aquaculture. DL creates both new opportunities and a series of challenges for information and data processing in smart fish farming. This paper focuses on applications of DL in ...

Three experiments were designed to investigate the heat increment of feeding (HiE) in Chinese shrimp, Fenneropenaeus chinensis. (1) Four groups of shrimp with different weight were fed at four rations to measure oxygen consumption in the following 24 h. (2) Four groups of shrimp with different...

This study investigated the energy flow and trophic structure of different polyculture ecosystems of the swimming crab Portunus trituberculatus using an Ecopath with Ecosim (EwE) model. Specifically, we aimed to characterize the trophic structure and biomass interactions, in parallel to assessing...

Five light intensity treatments (60 lx, "CL"; 600 lx changed to 60 lx, "FL1"; 1500 lx changed to 60 lx, "FL2"; 3000 lx changed to 60 lx, "FL3"; 6000 lx changed to 60 lx, "FL4") were tested to determine the growth of Litopenaeus vannamei under periodic light intensity change conditions. After 45-day ...
