Abstract:

Variation in esterase isozymes expression of 19 different tissues of the Asian catfish (Clarias batrachus) and African catfish (C. gariepinus) was studied. These tissues were: liver, anterior muscle, mid muscle, tail muscle (ventral region), tail muscle (tip region), buccal muscle, stomach, foregut, midgut, hindgut, kidney, gill, heart, eye (lens), eye (black portion), pelvic muscle, fore-, mid- and hind-brain. Maximum five esterase bands, viz. Est-11.83, Est-21.50, Est-31.15, Est-41.00 and Est- 50.17 were observed in the Asian catfish and four bands, viz. Est-21.50, Est-31.15, Est-41.00 and E

Abstract:

Although the vast majority of fossil catfish material is isolated elements such as fin spines, a number of fossil catfishes (Siluriformes) have been named based on articulated crania from Palaeogene formations of Africa. The fossil taxa from marine sediments have been assigned to the extant marine family Ariidae, or have been assumed to have washed into marine sediments from freshwater habitats. The ability to assess the relationships of these fossils without reference to the nature of the geological sediments may provide insight into the history of these families.

Abstract:

The culture of African catfish, Clarias gariepinus, is constrained by the high mortality of fry, occasioning a shortage of high-quality seeds for stocking by farmers. Asia, a continent with many success stories for aquaculture, leads in farmed production of some catfishes, a diverse group of 37 different families. Globally, the culture of catfishes ranks fifth in global farmed finfish production. Globally, Vietnam leads in the production and export of farmed striped catfish, Pangasianodon hypophthalmus, with 1,400,000 tonnes produced annually from about 7,000 hectares.

Farming african catfish Clarias sp at high stocking densities can foster stress and bacterial infection. In recent times, african catfish have frequently been discovered displaying symptoms of yellow body jaundice, often resulting in mass mortality. The objective of this study was to identify and characterize bacteria linked to jaundice in african catfish. Bacterial isolates were obtained from ten african catfish with yellowish body symptoms, identifying six dominant isolates.

Aquaculture has become a crucial component of global food production, yet catfish (10.8% of global finfish production) breeding programs often lack sufficient genetic data to fully utilize their production potential.

The modern biotechnologies of reproduction and cultivation of European catfish, African clary catfish and pangasius are considered. The development of biotechnology led to the development of a technology for its reproduction by the method of hormonal injection with preservation of life of the females and the euthanasia of the males for the collection of pure sperm. Further development of biotechnology is associated with the expansion of species diversity and the inclusion of African clary catfish and pangasius into aquaculture in warm waters.

Abstract:

The North African catfish (Clarias gariepinus) is a significant species in aquaculture, which is crucial for ensuring food and nutrition security. Their high adaptability to diverse environments has led to an increase in the number of farms that are available for their production. However, long-term closed breeding adversely affects their reproductive performance, leading to a decrease in production efficiency. This is possibly caused by inbreeding depression. To investigate the root cause of this issue, the genetic diversity of captive North African catfish populations was assessed in this st

The problem is urgent, because industrial aquaculture changes the biology of African catfish so much that it loses its ability to reproduce naturally.

Questions of age selection of producers and age composition of breeding stock in this type of fish are still open. In practice, we have to face the facts of poor quality of sexual products in primary spawning or old females
