Catchability changes depending upon fish behavior and abundance and the type and deployment of fishing gear (Blackhart et al., 2006).
The extent to which a stock is susceptible to fishing. Catch includes all fish killed by the act of fishing, not just those landed (FAO, n.d.).Ĭatchability ( syn.: Vulnerability) – 1. Discards may occur for regulatory or economic reasons (NRC, 1999).Ĭarrying capacity – The maximum population of a species that an area or specific ecosystem can support indefinitely without deterioration of the character and quality of the resource (Blackhart et al., 2006).Ĭatch ( syn.: Harvest) – The total number (or weight) of fish caught by fishing operations. Includes placement of larvae, level of parental protection and length of gestational period (Patrick et al., 2009).īiological functional unit – In reference to designing Territorial Use Rights for Fishing, the geographical range of a self-sustaining stock or sub-stock of fish.īycatch ( syns.: Incidental catch, Non-target catch/species) – Fish other than the primary target species that are caught incidental to the harvest of those species. At-sea monitoring is conducted with onboard observers or an electronic monitoring system.īreeding strategy – Provides an indication of the level of natural mortality that may be expected for offspring in the first stages of life. In the case of area-based programs, the unit is a specified area.Īrea-based catch share – See Territorial Use Rights for FishingĪt-sea monitoring – The collection of information on fishing activities taking place at sea, including harvesting, catch handling, biological sampling, fishing methods and interactions with protected species. It is often calculated as a percentage of the catch limit based on a participant’s holdings. See SEASALT.Īllocation – Distribution of a secure share of the catch to individuals or groups.Īnnual allocation unit ( syn.: Quota pounds) – The measure used to determine the annual amount of fish each participant is allowed to catch, usually defined as total weight. See SEASALT.Īge-length data – Data comparing the length of an individual fish with its age.Īll sources – In reference to the attributes of a catch share program, shares include all sources of fishing mortality (landed and discarded) and when combined do not exceed the catch limit(s) or other controls on fishing mortality. A B C D E F G H I J K L M N O P Q R S T U V W X Y ZĪccountable – In reference to the attributes of a catch share program, participants are required to stay within their allocated share of the overall catch and/or comply with other controls on fishing mortality.
