Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The rapid increase in world population has led to severe strain on resources leading to undesirable consequences like water scarcity and protein deficiency, especially in developing countries. Increased fish production from fish farming is a major solution to the dietary protein shortage but compounded fish feed is expensive and may be out of the reach of the ordinary fish farmer. There is a need for a low-cost system of fish production to cater for the food needs of poor and at the same time maximize the utilization of resources. Integrated fish farming (IFF) is such a low-cost system and it involves the combination of fish farming with other human activities especially agriculture. This book lays down the basic concepts and practice of integrated fish farming in terms of the history, present status, necessity, types, combination ratios etc. Cost-benefit analyses of some IFF systems are also explored; the health risks to human beings and fish from IFF systems and water quality issues are also treated. The book will be of interest to students, researchers, farmers, extension agents, health authorities and the general public.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Heavy metal pollution can occur from indiscriminate discharge of wastes into waterbodies and heavy metals are well-known toxins for man and animals. River Galma is the main drainage channel in Zaria and the river receives copious industrial effluents, agricultural wastes and domestic effluents including sewage from adjoining settlements. Thus, there is every possibility of contamination of water, sediments and fish in the River by heavy metals because of their persistence, toxicity and bioaccumulative nature. The few works on heavy metal loads in the River concentrates on river water and no work was found concerning Galma River fish or sediment as at the time of this study. This work investigates the concentrations of Cadmium, Chromium, Copper, lead and Zinc in the water, sediments and fish (O. niloticus and S. schall) River Galma with the aim of determining environmental risks and the suitability of fish for human consumption. The study will be of interest to students, researchers, health authorities and the general public.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Integrated Chicken-fish farming (ICFF) is a type of animal-fish farming and is a low cost system of fish production that involves the combination of chicken farming with fish culture. However, its practice entails the risk of transfer of pathogens to humans through the consumption of fish grown with chicken manure. In addition, heavy metal deposition into the fish receptacle through manure and spilled chicken feed may lead to metal concentrations in excess of permissible limits. This work assesses the effect of chicken wastes (manure and spilled feed) on the physico-chemical parameters and heavy metal concentrations in a chicken-fish system with the goal of determining the best combination ratio for laying chicken and fish under direct fertilization. The study recommends a combination ratio of 3,000 laying chickens and 80,000 fingerlings per 1 hectare fish pond for a vertically integrated chicken-fish system. Metal concentrations in the muscles of the two fish species used for the study (Oreochromis niloticus and Clarias gariepinus) were below FAO limits and the consumption of fish muscle from such systems operating within the combination ratio and culture period used for the study.…
