2 - Challenges and Concerns in Capture Fisheries and Aquaculture
Published online by Cambridge University Press: 10 February 2021
Summary
Introduction
Fish, taken here to mean all living aquatic products harvested by humans, are a critical source of protein, lipids and micro-nutrients in people's diets in the North and South alike. Fish are often part of the staple diet in developing and less-developed countries, and consumption of fish in developed countries has increased with its heavy promotion as healthy food and upmarket food sources. Global concerns about fish harvests, fish stocks, and the health of aquatic ecosystems are directly related to the increasing demand for fish as food and to the potentially short supply, due largely to overfishing and unsustainable fishing practices. Because fish are such an important part of the human diet, these concerns intertwine with social concerns such as fair allocation, improved livelihood and social well-being, and secure access to a safe food supply.
Fish are not only food for human consumption – they also serve ecosystem functions. From an anthropocentric point of view, fish as food for people is the central concern, reflecting management actions and goals. Recently, the importance of fish in their natural ecosystems has been recognised, resulting in the adoption of a more comprehensive approach to fisheries management. Challenges are thus based on acknowledgement of the interconnectivity of concerns for ecosystem health, social justice, livelihoods and food security and food safety.
The health of ecosystems determines their productivity. In capture fisheries, target species are often overexploited to the point where other parts of the aquatic ecosystem are affected. In the past, this problem was mainly addressed from the perspective of the overexploitation of single fish stocks. However, there is increasing awareness that the productivity of capture fisheries should be seen in the context of the overall health of the ecosystem and that ecosystem-based management of fisheries should be employed. Such a management approach aims also to address the problems of bycatch (including incidental catches and discards), and habitat damage caused by fishing gear.
Social justice is a key issue in fisheries, since the distribution of power and income and the allocation of rights change in relation to access to re- sources.
