PREFACE
This book provides current research on aquaculture. Chapter One reviews
management, challenges and developments of aquaculture in Ghana, West
Africa. Chapter Two covers the fundamental knowledge of phage infection in
bacterial cell and extends it to phage therapy by using a model of Vibrio-
phage, called VH-P, with its specific Vibrio harveyi host, VH 13- 1. Chapter
Three discusses taste-taint modelling in Recirculating Aquaculture Systems
(RAS) farmed fish. Chapter Four investigates the causative effect of protein,
lipid, feeding level and their interaction on growth, biological parameters and
haematology of Oreochromis niloticus. Chapter Five provides a review on the
mapping of the value chain for farmed fish and gender analysis along the
aquaculture value chain in Kenya. Chapter Six answers why aquaculture trials
have not been successful in Tanzania.
Chapter 1 - Food insecurity and malnutrition continue to pose a challenge
in Ghana. New ways of increasing availability, affordability and consumption
of protein and to improve alternative sources of livelihood are being exploited
in Ghana that has the climate, water bodies and other resources suitable for
aquaculture production. Aquaculture is currently practiced throughout the
country, with over 60% of farms in the southern and central belts according to
Ministry of Fisheries and Aquaculture Development (MoFAD) data. The fish
farming sub-sector in Ghana conventionally uses land-based production
systems since its start in the 1950s in the northern regions of Ghana. Dugouts,
reservoirs and dams were primarily used as fish culture systems. Modern
aquaculture techniques were introduced over the last four (4) decades. Ponds
have been the turning point from enhancement stocking to raising fish in farm
units. To date, ponds represent over 50% of the total aquaculture production
units and contribute only about 6% to the total annual aquaculture production
