Individual Anchoveta(Engraulisringens) Fishing Quota and the Administration and Control of Fishing Activity in a Region of Peru

Aims:The research was carried out with the objective of determining whether the individual anchoveta(Engraulisringens) fishing quota for direct human consumption constitutes a regulatory alternative for the administration and control of fishing activity to the extent that it allows greater efficiency of the industry, the increase in value total fisheries, the improvement in the safety of fishing and the sustainability of the hydrobiological resource. Methodology:The research is applied, non-experimental type and descriptive correlational design. The sample consisted of 50% of National and Comparative Legislation, Doctrine, Jurisprudence and Specialized Records on fishing issues; and by 30 experts in fisheries: lawyers 25% and representatives of fishermen 25%, from the District of Chimbote; Two questionnaires were developed to collect the data of the variables under study. Results:The results are presented in tables and statistical figures. The results showed that the individual quota of anchoveta(E.ringens)fishing for direct human consumption constitutes 43.3% a regulatory alternative to administer and control the fisheries administration, Chimbote, 2018. Conclusion:It was evidenced that the individual quota for fishing for direct human consumption allows a greater efficiency of the industry, the increase in the total value of the fisheries, the improvement in the safety of fishing and the sustainability of the hydrobiological resource. The individual fishing quota is a system that deserves to be seriously evaluated in Peru, with a broad participation not only of fishing entrepreneurs, but also of the various actors of civil society.

Testing a passive deterrent on longlines to reduce sperm whale depredation in the Gulf of Alaska

In Alaska, sperm whale (Physeter macrocephalus) depredation on longline sets has increased since implementation of the Individual Fishing Quota programme in 1995. A collaborative effort (SEASWAP) between longliners, scientists, and managers has undertaken research to evaluate this depredation with a primary objective to develop and test a passive deterrent that would reduce depredation without reducing catch rate of sablefish (Anoplopoma fimbria). Commercial longliners, fishing for their own sablefish quotas during the regular season, deployed beaded gear (25 mm lucite beads attached to gangions) with control gear and set recorders to collect acoustic data. Beaded and control gear were randomly assigned by skate quad (672 hooks) with 5 quads in each longline set. Acoustic recorders were used to document sperm whale creak–pause events, representative of depredation of the longline gear. Although there were more sablefish per skate quad on the beaded gear and there was a decrease in depredation events on the beaded gear compared with the control, neither effect was significant (p = 0.205 and 0.364, respectively). The SEASWAP project is testing other deterrent strategies including gear modifications and the establishment of a sighting network to improve avoidance.

Recovery of the Bristol Bay stock of red king crabs under a rebuilding plan

Kruse, G. H., Zheng, J., and Stram, D. L. 2010. Recovery of the Bristol Bay stock of red king crabs under a rebuilding plan. – ICES Journal of Marine Science, 67: 1866–1874. After peak landings in 1980, the red king crab fishery in Bristol Bay (Alaska) was closed in 1983 because of stock collapse. In the following decade, small commercial harvests and additional fishery closures (1994 and 1995) associated with depressed stock status prompted a reappraisal of the management strategy. A length-based population model was developed, which provided an improved stock assessment for setting annual catch quota. A management strategy evaluation revealed that a harvest strategy, which included a stair-stepped harvest rate of 10–15% of mature males and a threshold for effective spawning biomass below which no fishing is permitted, provides for relatively high long-term yield, greater stability in yield, fewer fishery closures, and higher effective spawning biomass. This strategy was adopted in 1996, in addition to crab bycatch caps and closed areas, to protect sensitive crab habitats implemented in the management of the groundfish trawl fishery. Since then, abundance of legal-sized males increased by 58%, that of mature males doubled, and mature female abundance and effective spawning biomass tripled through 2008. The stock has been considered rebuilt since 2003. Subsequently, a sharp reduction in fishing capacity improved profitability of the fishery, after implementation of an individual fishing quota programme in 2005.
