World Fisheries Resources provides a comprehensive and up-to-date review of how this commodity is used. The author examines the various aspects of fishing resources from their biological basis through to marketing and consumption. The subject is set in context by tracing the historical development, from its archaeological origins to the industrial expansion of the 19th and 20th centuries. The work comes up-to-date to discuss the modern situation and current trends in both the developed and developing worlds and highlights how exploitation of the resource has increased in recent years

With increasing human population, rising consumer demand, and intensification of industrial fishing, many valued fisheries are in decline. This review and synthesis explores how genetics informs classical fisheries management programs, especially in the context of managing declining fisheries resources. Discussing underlying principles and illustrative case studies drawn as possible from Southeast Asia, I focus upon application of genetics to: (1) define biologically based management units, (2) monitor the impacts of fisheries and fishery management actions, and (3) guide and evaluate fisheries restoration activities. Because overexploitation and declining fisheries arise from issues of economics, sociology, and politics, an effective approach to their solution must itself be interdisciplinary; application of genetic principles provides a valuable addition to such a holistic fisheries management program. Increasingly, progressive fisheries management agencies have in-house capabilities for genetic assessment and monitoring functions. Against this background, developing countries might seek to build their capacity for applied population genetics, either within fisheries management agencies or via scientific collaboration with research-oriented universities. While much progress has been achieved, the task of applying genetics to the effective management of declining fisheries is large and mostly before us.

Fisheries in Bohai Sea occur in an ecosystem, with different provinces conducting fishing activities on different species using different gears. Coordination of government actions continues to be a problem, as there exists many contradictions between different sectoral planning approaches. With the absence of a holistic institutional framework of management mechanism, coastal and marine resources are being destroyed. It has been found out in the study that fisheries resources in Bohai Sea, especially traditional high-valued species such as small yellow croaker, hair tail and Chinese prawn, have been over fished, and they have been replaced by some lowvalued species, mostly primarily smaller pelagic species, such as Japanese anchovy, half-fin anchovy etc. The effects on trophic level changes have been caused by mainly due to impacts from human activities and the variation in natural environmental problem like pollution. The CPUE declined from 2.39 tons/ kilowatt in 1950's to 0.91 tons / kilowatt in 1990's. The Bohai Sea being an important spawning, nursery and feeding ground for many migratory species from the Yellow Sea and at the same time supporting an important penaeid shrimp fishery it deemed important to carry out this work. The paper is divided into six sections. The first section is a brief introduction of the physical and biological characteristics of the region. Following is the description of methodology used in this paper. The data used in this study are listed in third section. The next section describes the major fisheries and specie shifts in dominance, and examines of the causes of resource variability are given in section five. Suggestions for restoring the resources of this ecosystem are offered in the final section.

This book synthesises the historical trends of the lake fisheries, the lake ecology, biology and biodiversity, socio-economics, stock assessment, aquaculture, fish quality assurance, environmental quality and management of the fisheries resources. The evolution of fisheries in Lake Victoria has undergone dramatic changes over the last few decades, leading to both ecological and socio-economic consequences. The lake has changed from one dominated by haplochromines in the 1950s, to one currently dominated by Nile perch, 'dagaa' (Rastrineobola argentea) and Nile tilapia. These changes have mainly been driven by the introduction of the predatory Nile perch in the lake, eutrophication due to increased human activities in the catchment, increased human population growth, overfishing and changes in the global climate system. This work should therefore be a particularly useful reference to fisheries scientists and managers, potential investors, students and other professionals who may be interested in the Lake Victoria fisheries

Lack of fish catch is one of the problems faced by coastal communities. From the fish farming activities in the sea, the community can obtain enormous economic benefits and support the economic growth of the family through the sale of fish from aquaculture. The government has given the opportunity and responsibility to the community in managing its resources, where the community itself has a need, goals, and aspirations and the community also makes decisions for their welfare. Socialization is needed regarding the importance of keeping coral reefs because the benefits are very good for coastal communities. The challenge faced is because coastal communities are increasing the ability and knowledge of the community about the importance of protecting ecosystems and capturing fisheries that are safe for the environment.
