The book Fisheries Resource Conservation discusses contemporary issues affecting global fish populations. This book describes insufficient conservation measures, jurisdictional disputes and illegal fishing vessels as some of the issues that threaten fish stocks. It stresses that there's an urgent need to adopt sustainable fishing practices, since communities that depend on fishery resources risk having their livelihoods stopped when fish populations are threatened. This book mentions the impact of globalization on local fish stocks, where the influx of external fishing boats into coastal waters has severely affected some countries' ability to fulfill domestic demand for the commodity. People must understand the importance of preserving fish populations if it's to be used as a long-term food resource.
