The genetic diversity of five natural populations milkfish (Chanos chanos) collected in Nghe An, Quang Binh, Binh Dinh, Phu Yen, Khanh Hoa provinces Vietnam was examined using COI gene sequence analysis. Twelve haplotypes were noted from a total 50 sequences along with 12 variable sites and 6 parsimony informative sites. population had the highest haplotype (0.889 ± 0.060) nucleotide diversitie...

Betanodaviruses are the causative agents of viral nervous necrosis (VNN) in cultured marine fish. A total of 237 apparently healthy aquarium fish, marine (65 species) and freshwater (12 species) fishes and marine invertebrates (4 species), which were stocked in a commercial aquarium in Seoul, South Korea, were collected from November 2005 to February 2006. The brains of the fish and other tissu...

The fluctuation of temperature affects many physiological responses in ectothermic organisms, including feed intake, growth, reproduction, and behavior. Changes in environmental temperatures affect the acquisition of energy, whereas hepatic glycogen plays a central role in energy supply for the homeostasis of the entire body. Glycogen phosphorylase (GP), which catalyzes the rate-limiting step i...

Milkfish is an important aquaculture species in Taiwan, and its high mortality during cold snaps in winter usually causes huge economic losses. To understand the effect of hypothermal stress and the corresponding compensatory stress response in milkfish, this study aimed to compare liver and gill protein levels between milkfish exposed to nonlethal (18°C), lethal (16°C), and control (28°C) temp...

In the first quarter of 2022 (1 January – 31 March) in Indonesia, there are problems related to increase prices basic necessities which can amount initial capital needed a milkfish (Chanos-chanos) cultivation business. So it is necessary conduct an simulation study feasibility analysis determine and business for 2022. The method used this library research method, where data collection entirely ...

Indications of milkfish larvae problems show lack symptoms vitamin C in the tissues, which will cause defective bone formation and become an inhibitor factor growth mortality. This research aims to investigate influence bioencapsulation on rotifer artemia protein retention, fat, energy, death (Chanos chanos). The dose used this study were 0 (control), 50, 100, 150, 200 mg L-1. treatment starts ...

Salmonella spp. is a bacterium that causes Salmonellosis and can cause food-borne illness to humans. The presence of in fresh milkfish affect quality aspects, deterioration fishery products, food safety. Microbiological testing an important indicator checking for contamination food. main factor causing be the pathogenic bacterial ingredients. purpose this study was detect on (Chanos chanos) sol...
