The roles of different forms of cytochrome P-450 in activation and deactivation of toxic chemicals, synthesis and breakdown of steroid hormones, and other functions, indicate the significance of these enzymes. Monooxygenase systems have been studied in species from several phyla of aquatic organisms. However, cytochrome P-450, the dominant catalyst in xenobiotic monooxygenase activity, is best ...

Acoustic telemetry is the primary method to actively track aquatic animals for behavioral studies. However, the small storage capacities of the batteries used in the transmitters limit the time that the implanted animals can be studied. In this research, we developed and implemented a battery-free acoustic transmitter that uses a flexible piezoelectric beam to harvest energy from fish swimming ...

Aquatic animals are important to health-conscious consumers due to their high content of polyunsaturated fatty acids (PUFA) particularly omega-3 FA. This paper reports the fat contents and fatty acid profiles of 20 species of marine fish and 6 species of squid and shrimp (obtained in the fishing port of Pattani, Thailand), in addition to 7 types of Thai freshwater fish to create a fatty acid da...

The emphasis in this review will be on Na(+) absorption across the skin and gills of vertebrates and the gills of crustaceans. However, some recent studies of Cl(-) uptake, especially in crustaceans, will also be described.

aquaculture is the fastest growing food production sector in the world today, supplying half of global fish consumption. Production from capture fisheries has stagnated and is unable to meet the anticipated growth in demand. current indications are that asian and african aquaculture will need to grow substantially to meet future demand for fish and must do so largely by increasing production pe...

The aquatic parasite usually classified in six groups include Protozoa (Phylum Rhizopoda, Phylum Mastigophora, Phylum Ciliophora, Phylum Myxozoa, Phylum Microspora, Phylum Apicomplexa), Phylum Platyhelminthes (Turbellaria, Monogene, Digenia, Cestoda), Phylum Nematoda, Phylum Acanthocephala, Phylum Annelida and Phylum Arthropoda (Branchiura, Copepoda, Malacostraca (order Isopoda)). Because of th...

Abstract Species coculture can increase agro-biodiversity and therefore constitutes an ecological intensification measure for agriculture. Rice-aquatic animal coculture, one type of species has been practiced researched widely. Here, we review recent studies present results a quantitative analysis literature on rice–aquatic systems. We address three questions: (i) rice yield soil fertility be m...
