The effects of rearing water depths and feed types on the growth performance of African catfish ( Clarias gariepinus )

Abstract

The suitability of the African catfish (Clarias gariepinus) to aquaculture throughout its distributional range started to be recognized in the middle of the 1980s. Over 30 years later, this species is now farmed either commercially or for subsistence in almost every country in sub-Saharan Africa as well as in North Africa and many other countries around the world (Dauda, Natrah, Karim, Kamarudin, & Bichi, 2018). Given its biology, it is easy to understand the appeal of C. gariepinus for aquaculture. Its ability to air breathe enables it to thrive in both temperate and tropical climates which helps explain why it is so widely distributed. In addition to its air breathing ability, which makes it hardy and versatile, it is able to feed on a diverse array of natural prey and it is highly fecund which makes it easy to spawn in aquaculture conditions. Of particular appeal is the ability of C. gariepinus to tolerate fairly poor water quality and to be cultured at higher stocking densities without additional pond aeration or high rates of water exchange (Hengsawat, Ward, & Jaruratjamorn, 1997).

Feeding behaviour, locomotion rhythms and blood biochemistry of the neotropical red‐tail catfish (Phractocephalus hemioliopterus)

“…hemioliopterus are scarce in the literature. In this study, the animals showed superior performance when compared to other juvenile catfish (Siluriformes), such as Asian red‐tail catfish ( Hemibagrus wyckioides ) (Deng et al ., 2011), yellow catfish ( Pelteobagrus fulvidraco ) (Wu, Zhou, et al ., 2018a), African catfish ( Clarias gariepinus ) (Abdel‐Hay et al ., 2020), hybrid catfish ( Pseudoplatystoma reticulatum × Pseudoplatystoma corruscans ) (Sousa et al ., 2020) and jundiá ( Rhamdia quelen ) (Rodrigues et al ., 2020). Regarding the self‐feeding system, similar performance results were described in other studies.…”

Molecular Characterization and Evaluation of Antibiotic Resistance Gene of Bacteria Associated with Gills of Arius heudelotii and Clarias gariepinus

“…Osawe [4] identified good qualities of catfish, such as its survival in different cultural systems and diverse environments. Catfish can grow fast, and the air breathes, which makes it vital to the sustainability of the aquaculture industry in Nigeria [3], [5].…”

Effect of feed pellet size and tank water level on growth performance in juvenile pikeperch, Sander lucioperca (L.), reared in a recirculating system

“…In aquaculture studies, little attention has been paid to tank water level, which is a crucial factor affecting the growth, survival, yield, and welfare of fishes. While there are several studies on the impact of water levels on the survival, growth, and behavior of different fish species in recirculating aquaculture systems (RAS) (Einarsdóttir and Nilssen 1996, Flodmark et al 2004, Koz³owski et al 2009, more attention has been focused on water depths in ponds (El Naggar et al 2006, Ali et al 2013, Hosen et al 2019, Abdel-Hay et al 2020) and the impact of water level fluctuations on the species communities in rivers, lakes, and reservoirs (Kahi et al 2008, Bucat et al 2012. In pikeperch tank water levels might affect its growth, because this species takes feed mainly from the water column (Zakêoe 2009, Koz³owski et al 2014).…”
