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%). -
Freshwater Fish Survey of Homadola-Nakiyadeniya Estates, Sri Lanka
FRESHWATER FISH SURVEY OF HOMADOLA-NAKIYADENIYA ESTATES, SRI LANKA. Prepared by Hiranya Sudasinghe BSc. (Hons) Zoology, M.Phil. reading (University of Peradeniya) INTRODUCTION The diversity of freshwater fishes in Sri Lanka is remarkably high, with a total of 93 indigenous fishes being recorded from inland waters, out of which 53 are considered to be endemic (MOE, 2012; Batuwita et al., 2013). Out of these, 21 are listed as Critically Endangered, 19 as Endangered and five as Vulnerable in the National Red List (MOE, 2012). In addition, several new species of freshwater fishes have been discovered in the recent past which have not yet been evaluated for Red Listing (Batuwita et al., 2017; Sudasinghe 2017; Sudasinghe & Meegaskumbura, 2016; Sudasinghe et al., 2016). Out of the 22 families that represent the Sri Lankan freshwater ichthyofauna, the family Cyprinidae dominates, representing about 50% of the species, followed by the families Gobiidae, Channidae and Bagridae, which represent seven, five and four species, respectively. The remainder of the other families are each represented in Sri Lanka by three species or less. Four major ichthyological zones, viz. Southwestern zone, Mahaweli zone, Dry zone and the Transition zone were identified by Senanayake and Moyle (1982) based on the distribution and the endemism of the fish. The Southwestern zone shows the greatest diversity, followed by the Mahaweli zone, with the least diversity observed in the Dry zone. About 60% of the freshwater fishes occur both in the dry and the wet zones of the island while the rest are more or less restricted to the wet zone. Of the endemic fishes, more than 60% are restricted to the wet zone of the island while about 30% occur in both the dry and the wet zones. -

Fisheries & Biological Sciences, Ahmadu Bello University, Zaria, Nigeria 2. Surgery and Radiology, Faculty of Veterinary Medicine, Ahmadu Bello University, Zaria-Nigeria 3. 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. -

Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish Clarias Gariepinus
Proceedings of a Workshop on the Development of a Genetic Improvement Program for African Catfish African catfish (Clarias gariepinus) production has gained considerable importance in a number of African countries. The species has several desirable attributes that make it attractive for aquaculture development. It is easy to reproduce, it does not require specialized feed, it tolerates high stocking densities, it accepts artificial feed, it tolerates poor water quality, and very importantly, it is highly sought after in local markets and economically viable in pond production systems. The species is endemic to Africa. In 2007 the WorldFish Center organized a workshop in Accra, Ghana, hosted by the Water Research Institute, to review the status of the catfish industry in Africa and develop recommendations on how best to approach the issue of genetic improvement programs. The results of the workshop are presented in this volume.

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. -

Así descubrí que, mientras en algunas disciplinas resultaba fácil encontrar obras en una lengua autóctona o traducida, en otras brillaban por su ausen- cia. He de admitir que el hecho me impresionó, pues ponía al descubierto toda una serie de oscuras caren- cias que marcaron un propósito a seguir en la disciplina que me ha ocupado durante treinta años: la ictiología. -

VACUITY COEFFICIENT and DIET in CLARIAS JAENSIS (BOULENGER, 1909) in the MBÔ FLOODPLAIN (CAMEROON) Tchouante Tzukam Christelle G
Global Journal of Agricultural Research Vol.8, No.1, pp.26-37, March 2020 Published by ECRTD-UK Print ISSN: ISSN 2053-5805(Print), Online ISSN: ISSN 2053-5813(Online) VACUITY COEFFICIENT AND DIET IN CLARIAS JAENSIS (BOULENGER, 1909) IN THE MBÔ FLOODPLAIN (CAMEROON) Tchouante Tzukam christelle G. [1]*, Efole Ewoukem Thomas [1], Tagning Zebaze Pégis D. [1] and Tchoumboue [1] [1] University of Dschang; Faculty of Agronomy and Agricultural; Department of animal production ABSTRACT: The Diet of Clarias jaensis was studied in the floodplain of Mbô in Cameroon. In order to reduce over-exploitation through knowledge of the food habits, 230 fish caught by artisanal fishing methods were collected monthly between November 2016 and September 2017 in three sites (Menoua, Nkam and flooded ponds). The digestive tract dissection was made according to the standard method. The standard length and total weight of specimens ranged from 10.50 to 47.50 cm and between 9.99 and 1165.59 g respectively. Overall, 43 stomachs were empty with a general vacuity coefficient of 18.69%. It varied between 16.85 and 26.08%, respectively between the dry and rainy seasons, and then by 24.00; 11.43 and 26.00% respectively in the Menoua, Nkam and flooded ponds. The diet characterized on the basis of occurrence and numerical percentages, having varied from one season to another. Insect- dominated animal organic matter was significantly (p < 0.001) higher (73.54%) compared to plant matter (36.59%) and detritus (24.09%). The food spectrum of C. jaensis, with 9 items, showed that it was an omnivorous species with an insectivorous tendency. -
