The length of a fish as measured from the tip of the snout to the hidden base of the tail fin rays.
Industry:Fishing
The process of developing Federal regulations which occurs in several steps, including publishing proposed rules in the Federal Register, accepting comments on the proposed rule, and publishing the final rule. An "advanced notice of proposed rulemaking" is published when dealing with especially important or controversial rules.
Industry:Fishing
The average age of the fish in a year-class at which the instantaneous rate of natural mortality equals the instantaneous rate of growth in weight for the year-class as a whole. At this age, the biomass of the age class is maximum.
Industry:Fishing
Protein-rich meal derived from processing whole fish (usually small pelagic fish, and fishery bycatch) as well as residues and byproducts from fish processing plants (fish offal). Used mainly as agriculture feeds for poultry, pigs, and aquaculture feeds for carnivorous aquatic species.
Industry:Fishing
The increase in yield obtained by an increase in fishing effort (or fishing mortality) by one unit. In mathematical terms, it is given by the slope of the tangent to the relationship between effort and yield (or between fishing mortality and yield-per-recruit).
Industry:Fishing
Requires that "conservation and management measures shall prevent overfishing while achieving, on a continuing basis, the optimum yield from each fishery for the U. S. industry"; where "optimum yield" is defined in terms of the amount of fish which will provide the greatest overall benefit to the Nation.
Industry:Fishing
The extent to which a change in a stock or ecosystem induced by exploitation will reverse itself when the causative factor is removed. Extinction of a species is an example of an irreversible change.
Industry:Fishing
The concept that the number of young fish (recruits) entering a population is related to the number of parent fish (spawners).
