Effect of Three Diets on Growth and Survival Rates of African Catfish Heterobranchus bidorsalis Larvae Yao Laurent Alla1*, Ble Melecony Célestin1, Atse Boua Célestin1, Kone Tidiani2 1 Centre de Recherches Océanologiques, BPV 18 Abidjan, Côte d’Ivoire 2 Laboratoire d’Hydrobiologie, UFR Biosciences, Université de Cocody Abidjan, 22 BP 582 Abidjan 22, Côte d’Ivoire (Received 23.2.10, Accepted 14.4.10) Key words: Heterobranchus bidorsalis, growth, survival, Artemia salina, beef brain, formulated food Abstract Investigations are underway in the Centre de Recherches Océanologiques d’Abidjan (Côte d’Ivoire) to find whether the catfish (Heterobranchus bidorsalis) could be an interesting aquaculture species. Within this framework a 28-day aquarium culture feeding trial was conducted to investigate the effects of three diets (Artemia salina nauplii, beef brain enriched with vitamins, and a compound food) on the growth and survival rates in 2-day post hatch H. bidorsalis. The feeding experiments started after the yolk sac of the larvae was absorbed (initial mean weight = 2.03±0.38 mg). Larvae fed Artemia nauplii had a higher growth rate (final mean weight = 708.60±411.61 mg] than those fed beef brain (381.81±118.88 mg) or compound food (102.72±48.09 mg). Conversely, the beef brain diet yielded a better survival rate (70.47±9.48%) than the Artemia nauplii (38.72±7.74%) or the compound diet (5.37±2.24%). -

One of the world’s worst invasive species, Clarias batrachus (Actinopterygii: Siluriformes: Clariidae), has arrived and established a population in Turkey. Acta Ichthyol. Piscat. 50 (4): 391–400. Background. Ornamental freshwater fish releases constitute a remarkable proportion of the 100 worst invasive species worldwide. Early detection and knowledge of likely introduction vectors and pathways of potentially invasive fishes into sensitive habitats are key for their proper management, hence rapid and correct identification of their occurrence is crucial. -

Abstract The population structure and genetic diversities of Clarias gariepinus from the cultured population at Chi Farm (Ajanla) and wild population at Asejire Reservoir (Asejire) were analysed using Random Amplified Polymorphic DNA (RAPD) and Microsatellite DNA markers. Using a CTAB protocol, genomic DNA was extracted from the caudal fins of 20 samples of live specimen collected from each population. Seven RAPD primers and seven pairs of microsatellite DNA primers were used to amplify different loci on the extracted genomic DNA by Polymerase Chain Reaction and the resultant DNA fragments were analysed on agarose gel. The RAPD primers amplified a total of 474 loci with 697 bands in all samples for the seven primers studied. -

African Sharptooth Catfish Clarias Gariepinus
African sharptooth catfish Clarias gariepinus 1 Taxonomy Species: Clarias gariepinus (Burchell, 1822) Family: Clariidae Order: Siluriformes Class: Actinopterygii African sharptooth catfish Clarias gariepinus is a typical air-breathing catfish with a scaleless, bony elongated body with long dorsal and anal fins, and a helmet like head (Figure 1). Colour varies dorsally from dark to light brown and is often mottled with shades of olive and grey while the underside is a pale cream to white (Skelton 2001). It can grow very large with a maximum reported length of 170 cm (IGFA 2001) and weight of 60 kg (Robbins et al. 1991). Figure 1. Lateral view of Clarias gariepinus (Source: FAO 2012). The genus Clarias was reviewed in the 1980s, which resulted in several widespread species being synonymized (Clarias capensis of southern Africa, C. mossambicus of central Africa and C. lazera of west and north Africa) under the name Clarias gariepinus (Teugels 1986). 2 Natural distribution and habitat The native range of C. gariepinus covers most of the African continent, with the exception of Maghreb, Upper and Lower Guinea, and the Cape provinces of South Africa (Picker & Griffiths 2011) (Figure 2). According to Skelton (2001) it is probably the most widely distributed fish in Africa. Jubb (1967) describes its natural distribution as occurring as far south as the Orange River system in the west and the Umtamvuna River in the east of South Africa. Page | 1 C. gariepinus is widely tolerant of many different habitats, even the upper reaches of estuaries, but is considered to be a freshwater species. It favours floodplains, slow flowing rivers, lakes and dams (Skelton 2001). -

Comparative Study of Growth Parameters of African Catfishes As Panacea for Food Security
Nigerian J. Anim. Sci. 2019, 21 (3): 179-192 Comparative study of growth parameters of African Catfishes as panacea for food security *1Abanikannda, O.T.F., 2Jimoh, A.A., 1Abagun, A.A. and 2Badmus, L.A. 1Department of Zoology and Environmental Biology, Lagos State University, Ojo – Lagos, Nigeria 2Department of Fisheries, Lagos State University, Ojo – Lagos, Nigeria *Corresponding Author: [email protected] Phone Number: +234 802 312 8376 Target audience: Fish farmers, Scientists, Government policy makers Abstract Aquaculture assist in bridging the wide gap by meeting demands for fish and provision of less expensive animal protein in Nigeria. Clarias gariepinus and Heterobranchus bidorsalis are generally acceptable important species of catfish, and highly priced because of their high biological values in terms of protein retention, assimilation and low cholesterol content, necessitating the need to evaluate their potentials. Fingerlings of Clarias gariepinus (purebreed) and Clariabranchus (hybrid) were grouped according to their weights, assigned to two tanks each and fed 5% of their body weight daily. Measurements of body weight (g), total length (cm) and standard length (cm) were taken weekly on each fish. At the commencement of the experiment, there were 281 fishes comprising 150 pure breed and 131 hybrids. By the end of the study some died or were outliers. A total of 224 fishes comprising 108 pure breed and 116 hybrids were finally evaluated. Indices computed included Length-Weight Relationship (LWR), Fulton’s Condition Factor (K), Absolute Growth Rate (AGR), Specific Growth Rate (SGR), Relative Growth Rate (RGR) and Mean Growth Rate (MGR). The coefficient of the LWR was respectively 2.42 and 2.82 for the pure breed and hybrids.
