Contrary Evidence

The potential of fishing mortality to cause rapid evolutionary changes in life history has received relatively little attention. By focusing only on ecological responses, standard fisheries theory and practice implicitly assume either that genetic influences on life history in the wild are negligible or that natural selection and adaptation is a slow process that can be effectively ignored. Lack of contrary evidence has allowed these assumptions to persist. Drawing upon >25 years of research on the Atlantic silverside (Menidia menidia), we show that adaptive genetic variation in many traits is finely tuned to natural variation in climate. Much of this variation is caused by a gradient in size-selective winter mortality and involves two- to threefold changes in physiological traits that influence population productivity. Many other species are now known to display similar patterns. Harvest experiments show that these traits can evolve rapidly in response to size-selective fishing. Hence, the pool of genotypes that code for life history traits is a highly dynamic property of populations. We argue that the lessons from Menidia are applicable to many exploited species where similar observations would be difficult to obtain and advocate greater use of species models to address fundamental questions in fishery science.

Fishery Science

In 1960th, red king crab was intentionally introduced into the Barents Sea. This species has formed a new self-sustaining population. In Russian waters, the commercial fishery of red king crab was started in 2004. Non-indigenous status and high commercial value of the crab have led to growing interest in the study of its biology and ecology. Red king crab has been intensively studied by specialists of Murmansk Marine Biological Institute to evaluate the role of this crab in local benthic communities and provide a theoretic basis and important applications for fishery science. New data on the population dynamics, symbiotic relationships, feeding and reproduction of red king crab have been obtained from long-term studies in coastal waters of the Barents Sea. Significant results of these studies are presented in this review.

A role of Russian science is increasing along with domestic fisheries development in the world Ocean. One of the main tasks of researchers is to protect the interests of Russian fisheries on the international level. Such protection is based on living resources investigation and formulation of recommendations on their sustainable development, taking into account the international regulations’ and bilateral agreements’ demands.

The definition of the word stock, as applied in fishery science, is presented in general and in precise forms. The general definition is a species group, or population, of fish that maintains and sustains itself over time in a definable area. In a more precise manner, stock (genotypic) is defined as a population of fish maintaining and sustaining Castle–Hardy–Weinberg equilibrium. If a genetic basis is not available for stock characterization, then a phenotypic stock definition has to be recognized as a population of fish maintaining characteristics which are expressed in one or more ways, depending on the type or nature of environment of domicile.Key words: fish stocks, definition

Simple Equations

Modern fishery science, which began in 1957 with Beverton and Holt, is ca . 50 years old. At its inception, fishery science was limited by a nineteenth century mechanistic worldview and by computational technology; thus, the relatively simple equations of population ecology became the fundamental ecological science underlying fisheries. The time has come for this to change and for community ecology to become the fundamental ecological science underlying fisheries. This point will be illustrated with two examples. First, when viewed from a community perspective, excess production must be considered in the context of biomass left for predators. We argue that this is a better measure of the effects of fisheries than spawning biomass per recruit. Second, we shall analyse a simple, but still multi–species, model for fishery management that considers the alternatives of harvest regulations, inshore marine protected areas and offshore marine protected areas. Population or community perspectives lead to very different predictions about the efficacy of reserves.
