Book excerpt: The manual is based on the practical experiences of the authors on the artificial reproduction and pond rearing of the African catfish Clarias gariepinus within FAO field projects in the Central African Republic, the Republic of the Congo, Kenya and Nigeria. The manual is divided into five major sections dealing with: 1) general biology, including natural feeding habits and reproduction; 2) artificial reproduction, including induced propagation without and through hormone injection; 3) fry nursing in earthen ponds, including pond preparation, fertilization, feeding and management; 4) monoculture, including feeding methods; and 5) polyculture with Tilapia. In addition, information is provided concerning the economics of different fingerling and grow-out farming practices in Africa, and concerning diseases and hybridization.

This book was released on 2010-10-28 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes represent astonishing diversity with respect to practically every aspect of their biology. Reproductive modes and sexual patterns are especially fascinating and provide deep insight into general evolutionary problems. In this volume, chapters focus on reproduction and sexuality among groups of fishes defined by habitat, taxon, and the reproductive processes that are critical for reproductive success. The book illustrates how knowledge of reproductive biology among marine fishes can help identify vulnerable and potentially vulnerable species in the face of changing environmental conditions and increasing human-based pressures.

This book was released on 2007 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third and main section of the document discusses ways of increasing the contribution of small-scale fisheries to poverty alleviation and food security through nine main entry points. First, the paper revisits conventional fisheries policies and legislation and makes suggestions on how those can be made more pro-poor. Next, the paper emphasizes the importance of capacity building and highlights how cross-sectoral interventions can greatly improve the livelihoods of fish-dependent communities. The paper then proposes a series of broad pro-poor or pro-small-scale fisheries principles, before discussing in greater detail three of the main management instruments adopted in fisheries: (i) property right approaches; (ii) co-management; and (iii) protected areas. The next two sub-sections discuss markets and how to make them work for the poor, and the important issue of pro-poor financing systems and subsidies.

This book was released on 2019-10-16 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2016 in the subject Biology - Botany, grade: A, University of Port Harcourt (Faculty of Sciences), language: English, abstract: The aim of this experimental research is to Study the effect of catfish farm effluent on the growth and germination of Abelmoschus esculentus and Vigna unguiculata. When fish are harvested from ponds, the effluent is often drained, presenting both an environmental threat and an agricultural wealth. Effluent discharge which is sequel to pond draining, has posed serious environmental threat, such effluent are often allowed to run into natural water ways, posing a potential source of pollution and eutrophication of water bodies. Clarias gariepinus, has been preferred for culture amongst fish farmers due to its ease of adaptability, less maintenance required, ease of multiplication and less demand for quality of water. Nonetheless culture of C. gariepinus, has become large enough to have significant impacts on the environment and natural resources, and a number of concerns have been expressed by both environmental activists and scientists.
