FISHTERM's fisheries quiz: level 3
Question 1: A (medium- or long-term) shift in environmental conditions that impacts the productivity of a stock. (Beamish et al. 1999)
Question 2: A stock assessment programme based on Schaefer´s form of the production model, with non-equilibrium tuning of biomass-based abundance indices. The population model is in lumped biomass.
Question 3: International treaty-based organisations (about 17 of them) establishing binding measures for conservation and sustainable management of highly migratory or straddling fish species, covering various geographic areas, some of which overlap.
Question 4: A stock assessment program based on length-based separable models and tuning of abundance indices. The population model is length/age-structured.
Question 5: A benchmark against which the abundance of the stock or the fishing mortality rate can be measured in order to determine its status. These reference points can be Limits or Targets, depending on their intended usage.
Question 6: A type of passive fishing gear having the form of a basket often placed at the bottom of water and used to trap fish, crabs, and other aquatic resources. ** Barrel-shaped structure made out of willow, with one or two funnel-shaped openings.
Question 7: A natural flow of water that continues in a long line across land to the sea/ocean
Question 8: To dehydrate fishery products through the direct action of heat produced by solar energy or some other source.
Question 9: Automotive vehicle with trailer designed to carry temperature-controlled goods.
Question 10: The extent to which a stock is susceptible to fishing; quantitatively, or fraction of the stock which is caught by a standardised (effective) unit of effort. It is also used as the constant of proportionality that relates effective effort to fishing mortality (q x f = F) or as the constant of proportionality that relates an index of abundance to absolute stock size (I = q x N).
