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%). -

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. -

Zoology & Biological Sciences, Ahmadu Bello University, Zaria-Nigeria *Correspondence: Tel.: +2348069675754, E-mail: [email protected] Abstract This study was designed to examine radiographically the morphological anomalies in artificially spawned 24-week- old Heterobranchus longifilis. A total of 22 morphological deformities observed from an F1 population of 4,871 were classified. Based on anatomical positions, most of the anomalies (49.99%) manifested in the bodies as stunted growth with a weight range of 240-358g, standard length (SL) of 18.7-29.1cm and stump body trait with a weight range of 445-810g, SL of 22.9-35.9cm. Anomalies of the vertebral column accounted for 27.27% with a weight range of 410-945g, SL of 27.4-36.8cm. Fin aberrations including agenesis were seen in 22.73% with a weight range of 548-840g, SL of 34.1-39.2cm. Radiographic examination revealed anomalies such as hypoplasia and hyperplasia of fins, supernumeracry and agenesis of fins, fin cleft, and fusion of fins, scoliosis and kyphosis. -

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. -

Embryonic and Larval Developmental Stages of African Giant Catfish Heterobranchus Bidorsalis (Geoffroy Saint Hilaire, 1809) (Tel
Olaniyi and Omitogun SpringerPlus 2014, 3:677 http://www.springerplus.com/content/3/1/677 a SpringerOpen Journal RESEARCH Open Access Embryonic and larval developmental stages of African giant catfish Heterobranchus bidorsalis (Geoffroy Saint Hilaire, 1809) (Teleostei, Clariidae) Wasiu Adekunle Olaniyi1* and Ofelia Galman Omitogun2 Abstract The dearth of African giant catfish Heterobranchus bidorsalis seeds poses great threat to its aquaculture and biodiversity, hence detailed knowledge and understanding of its embryology is indispensable for its artificial propagation and conservation programmes. Photomicrographs of extruded oocyte through all developmental cell stages of live embryo to larval stage are documented with the aid of a light microscope. The optical transparency of the developing embryo enabled us to describe its deep structures, distinctive features and characterize the stages pictorially. Extruded oocyte had a mean diameter of 1 ± 0.1 mm, ~20% increase when hydrated, and bounded by double thin perivitelline membranes. The first mitotic cleavage occurred at 69 min post-fertilization (pf) resulting in 2, 4 (2 × 2 array of cells), 8 (2 × 4), 16 (4 × 4), 32 (4 × 8), 64 (2 × 4 × 8) blastomeres, then developed to morula, blastula and gastrula stages. Blastula was featured by formation of enveloping layer and yolk syncytial layer. Onset of epiboly at 3 h 57 min depicted the commencement of gastrula while closure of blastopore at 11 h 8 min marked its completion. Neurulation period was distinct from segmentation where organogenesis was fully active. Embryo sudden muscular contraction was noticed at ~17 h pf, increased prior to hatching with caudal locomotion firstly at 42 s interval. Heartbeat of embryo commenced at ~1 h before its unique eclosion at average of 72 beats/min while first larva emerged at 21 h at a controlled temperature of 28.5 ± 0.5°C. -

Fish Hybridization in Some Catfishes: a Review
--- 220 Fish hybridization in some catfishes: A review Adah, P. M. / Onyia, L. U. / Obande, R. A. Abstract A review of hybridization of some catfishes shows that catfish hybridization among other aspects of biotechnology has continued to raise interest among researchers of various disciplines such asjish biologists, geneticists, aqua culturists, molecular biologists, nutrition scientists and so on. The studies sofar reported werefrom seasoned researchersfrom several works of life and disciplines who have direct or indirect interest onjish hybridization (especially catfishes).It could be thus, concluded that though there is a dearth in literary work on catfish hybridization considering their numbers and diversities.However, several interesting works can befound across the continents (especiallyAfrica, Asia, and North America) that show that catfish hybridization holds a very high potential for thefuture; a better catfish hybrid is equivalent to a better catfish aquaculture as well as it contribution to globalfood security. Keywords: Hybridization, catfish, aquaculture. Introduction ish production through aquaculture is an age long practice especially in Asia and Africa. For instance, production of the African catfishes Clarias gariepinus and Heterobranchus longifilis has been practiced for a long time in Africa. To Fensure fish food security in Africa, increased production of fry and fingerlings with -attributes of faster growth rates, high food conversion ratio and better environmental tolerance is greatly inevitable. Therefore, genetic techniques are needed to ensure the production offish breed with faster growth rate, very high feed conversion ability, leading to a shorter production cycle as well as a greater tolerance for poor water conditions. According to Jothilakshmanan and Marx (2013) hybridization studies in fishes are very scanty and only very few reports are available. -
