Genetic Diversity, Population Structure and Differentiation of Farmed and Wild African Catfish (Clarias gariepinus) in Nigeria

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT The African catfish (Clarias gariepinus) is a commercially important species, for both fisheries and aquaculture, and is now the most commonly farmed fish in sub‐Saharan Africa. However, knowledge about the genetic diversity and population structure of natural and farmed populations, which is crucial for effective conservation and sustainable ...

Variations of biofouling communities in an off-shore fish cage farm from North-Western Sardinia = Variazioni del biofouling in un allevamento ittico in gabbie off-shore della Sardegna nord-occidentale [PDF]

, 2010
Biofouling variations were studied in a fish farming facility near Alghero (Italy) between November 2007 and November 2008. Net panels suitable for the settlement of encrusting organisms were immersed in cages in which large and small gilthead seabream ...

17β-Estradiol regulates gilthead seabream professional phagocyte responses through macrophage activation

Developmental & Comparative Immunology, 2011
In mammals, estrogens regulate the immune system, either directly or indirectly via several leukocyte types through autocrine/paracrine mechanisms. In the gilthead seabream (Sparus aurata L.) gonad, an intensive remodeling process accompanied by the massive infiltration of acidophilic granulocytes (AG) is partially triggered by 17β-estradiol (E(2 ...

Aspects of comparative genomics in the gilthead seabream, Sparusaurata [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2006
Genome projects for new fish species are found in a transitional period during which resource development and meaningful com- parative genomics analysis or use of any other comparative approach must be done in parallel. In new species, full sequencing is still prohibitive due to the high cost of vertebrate genome sequencing and the fact that present ...

Cardiac activity cessation during slaughtering combinations in farmed European seabass

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Ensuring fish welfare during stunning and slaughter is essential, as these procedures represent critical points in the production cycle that can significantly impact animal welfare. Cardiac activity serves as a key physiological indicator to assess stress responses and welfare in fish.

Dorso-ventral skin characterization of the farmed fish gilthead seabream (Sparus aurata). [PDF]

PLoS ONE, 2017
The skin is the first barrier of defence in fish, protecting against any external stressor and preserving the integrity and homeostasis of the fish body. The aim of this study was to characterise gilthead seabream skin by isolating cells and studying the

What determines growth potential and juvenile quality of farmed fish species? [PDF]

, 2013
Enhanced production of high quality and healthy fry is a key target for a successful and competitive expansion of the aquaculture industry. Although large quantities of fish larvae are produced, survival rates are often low or highly variable and growth ...
