Download or read book Catfish Breeding A Do it Yourself Guide on Catfish Seed Production written by Anthony Adefarakan and published by Anthony Adefarakan. This book was released on 2024-08-14 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many farmers have in times past fallen victim to procuring bad fish seeds, leading to failure as they either died or refused to grow. This could be attributed to bad parent stocks, poor water management, poor stocking density, poor feeding, etc. on the producers’ part. To solve this problem once and for all, fish farmers must start producing their fish seeds (with all the needed care) for effective production, and this is what this handbook offers. It is written so that the farmer interested in hatching their fish can do so without necessarily being monitored or supervised, hence the name “Do-It-Yourself” guide. The pictures used are deliberately included to make it easy to perceive the whole process. With this guide, you are fully armed for catfish seed production.

Book excerpt: About the Book Many fish farmers have in times past fallen victim of procuring bad fish seeds, leading to failure as they either died or refused to grow. This could be attributed to bad parent stocks, poor water management, poor stocking density, poor feeding etc. on the producers' part except for those from farms with credibility which perform well and grow to good sizes. In solving this problem once and for all, it is necessary for fish farmers to start producing their own fish seeds (with all the needed care) for effective production, and this is what this handbook offers. It is written in such a way that the farmer who is interested in hatching their own fishes can do so without necessarily being monitored or supervised, the reason for the name "Do-It-Yourself" guide. The pictures used are deliberately included for easy perception of the whole process. With this guide at your disposal, you are fully armed for catfish seed production.

This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Selective Breeding in Aquaculture an Introduction written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2010-03-17 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.

Download or read book Small scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Download or read book Albion s Seed written by David Hackett Fischer and published by Oxford University Press. This book was released on 1991-03-14 with total page 981 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book is the first volume in a projected cultural history of the United States, from the earliest English settlements to our own time. It is a history of American folkways as they have changed through time, and it argues a thesis about the importance for the United States of having been British in its cultural origins. While most people in the United States today have no British ancestors, they have assimilated regional cultures which were created by British colonists, even while preserving ethnic identities at the same time. In this sense, nearly all Americans are "Albion's Seed," no matter what their ethnicity may be. The concluding section of this remarkable book explores the ways that regional cultures have continued to dominate national politics from 1789 to 1988, and still help to shape attitudes toward education, government, gender, and violence, on which differences between American regions are greater than between European nations.
