Times of poor fishing were explained by superstitions and dogma because few scientific facts were available. Fishermen even blamed the construction of lighthouses for poor catches. At the beginning, of course, fishing pressure was so low that its effect on large stocks of fish was undoubtedly minimal. Unable to display preview. Download preview PDF.
Norman Graham, Richard S. Ferro, William A. Graham, N. Fishing practice, gear design, and the ecosystem approach—three case studies demonstrating the effect of management strategy on gear selectivity and discards. Lack of marketing opportunities, quality considerations, or large price differentials between or within species highgrading all induce discarding Alverson et al. Crean and Symes note that the management framework has a strong influence on discard rates. Fisheries that are managed extensively by output controls [such as total allowable catch TAC and catch composition regulations] are often characterized by high discard rates.
Different fishing gear types have different impacts on bycatch, habitat, and the rate at which overfishing occurs. Different fish species live in different areas of the water column e. Different gear types can have varied impacts depending on their design, where they are used and what they are catching. This gear variance is why the same species may have different sustainability rankings or eco-certifications, depending on how it was caught. Likewise, different species caught by the same gear type can have different sustainability concerns.
