| Summary: | Life history characteristics such as asymptotic length L∞, growth rate K, the length at which 50% of the individuals have reached maturity Lmat, and natural mortality M are therefore often used to indicate the sensitivity of different species to fishing. When species-specific information is missing, an estimate of the maximum length Lmax of a species can be used to infer asymptotic length, growth rate, natural mortality, and proportion mature at length. Here, we provide a data base containing life history parameters of 271 species along with the references of these values and gear efficiency estimates for all species. Further, we provide average annual catch indices within inhabitated areas for each species. ... : Species recorded in the DATRAS survey database covering the Northeast Atlantic from the coast of Portugal to the North Sea and from the Baltic Sea to west of Scotland (http://www.ices.dk/data/data-portals/Pages/DATRAS.aspx) are included in the data. The maximum length of the species, Lmax, the asymptotic length, L∞, the von Bertalanffy growth rate parameter, K, length at first maturity, Lmat, and the length at which the individuals entered the sensitivity model (length at birth for chondrichthyan and length at metamorphosis for bony fish), Lmin, were derived from a comprehensive literature review. Bottom and beam trawls retain a variable proportion of the fish found in the path of the gear. Some species, such as shallow water or reef-associated species, are difficult to catch because their habitat is not consistently sampled during trawl surveys, while pelagic species, such as Atlantic herring Clupea harengus are found in the water column and may pass above the headline of the gear without being caught. ... |
