Catfish make up a large group of widely distributed freshwater fish. Clariid catfish (Clariidae) are the most widespread freshwater fish species in Africa and Asia. They are adaptable and can survive out of water for considerable periods if they remain moist. Catfish have evolved auxiliary...

The aquaculture subsector is important in Kenya for food and nutritional security. The rapid growth of the subsector is evident especially in the widespread culture of Nile tilapia (Oreochromis niloticus); however, the gains made in the industry may be curtailed by inadequate quality seed....

Amoebic gill disease (AGD) affects global marine aquaculture production of Atlantic salmon, requiring costly reiterative treatment and negatively impacting fish performance and welfare. Although there has been gradual and ongoing progress in genetic selection to improve host resistance to the...

Leopard coral grouper (Plectropomus leopardus) is a marine economic fish that widely inhabits the western Pacific. In recent years, the quantity of wild-captured leopard coral grouper has had difficulty meeting commercial and recreational needs. Therefore, it is necessary to develop the artificial...

Acute hepatopancreatic necrosis disease (AHPND) is a major bacterial disease of the Pacific white shrimp Litopenaeus vannamei. An effective phenotype measurement to evaluate disease resistance is crucial for selective breeding of shrimp. However, it is difficult to find a suitable phenotype to...

The present study attempted to understand the immune responses of resistant (RF) and susceptible families (SF) striped catfish (Pangasianodon hypophthalmus) of generation one tested and selected for resistance to Edwardsiella ictaluri, causative agent of bacillary necrosis of Pangasius. Two family...

This study was conducted to assess the influences of dietary β-glucan on growth rate, antioxidant status, immunity response, and resistance against Aeromonas hydrophila of genetically improved farmed tilapia (GIFT, Oreochromis niloticus). Four isonitrogenous and isoenergetic diets were formulated...

For the initiation of a genetic improvement program of any culturable fish species, the assessment of the genetic quality of different stocks is prerequisite. However, in Pakistan, such data of all culturable fish species including an indigenous Labeo rohita are lacking. Here, an attempt has been...

Accurate measurements of breeding traits on individuals are critical in aquaculture for obtaining breeding values and tracking the progress of the breeding program. Modern breeding programs prioritize not only production traits but also complex traits related to production, product quality, body...

Vibriosis is a bacterial disease in fish caused by the Gram negative bacterium Vibrio anguillarum with severe impact on rainbow trout (Oncorhynchus mykiss) farming. Sustainable control methods should be developed and we here show that marker assisted selective breeding of fish naturally resistant...
