Bioeconomic assessment of a change in fishing gear selectivity: the case of a single-species fleet affected by the landing obligation

The European Union Common Fisheries Policy has established a discard ban, which states that fish below a reference size cannot be sold directly for human consumption. In a fishing effort-regulated…

Balanced harvesting can emerge from fishing decisions byindividual fishers in a small-scale fishery

Catching fish in proportion to their productivity, termed balanced harvesting, has been suggested as a basis for the ecosystem approach to fishing. Balanced harvesting has been criticized as uneconomical and…
