Economics in Fisheries Research

By

Medwin Gale

Preface

Fisheries Research has been evolved over centuries. Its initial focus was on the identification of different species and their arrangement into systematic taxonomies. Later emphasis was on the ecology of the target species, their biomass and distribution, their behaviour, and the environment in which they lived

"Economics of fisheries" is a field of economic research that has developed since the mid-1950s. The core of the research in its early stage was to find conditions for optimal exploitation of fish stocks over time. The purpose is to inform policymakers about harvest levels that maximize net present value of the fish stock. At the same time, the fundamental insight was developed that in absence of effective regulation or collective control over harvest behavior the fish stocks tend to be overexploited from both a biological and economical point of view.

Fisheries science and modelling developed rapidly during a productive and innovative period, particularly among fisheries researchers of various disciplines. Population modelling and fishing mortality were introduced to economists, and new interdisciplinary modelling tools became available for the economists, which made it possible to evaluate biological and economic impacts of different fishing activities and fisheries management decisions.

Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, conservation, ecology, population dynamics, economics and management to attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bioeconomics and fisheries law.

The farming of aquatic organisms like fishes, aquatic plants, molluscus, crustaceans etc, is known as aqualculture. Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.

The main focus of this book is the economic aspect of fisheries research. It is enriched with experiences in developing countries because this is where much of the innovative work in fisheries research is being carried out.
