  • Help to protect the population of cod fish and yellowtail fish 
  • The closure only affected 3.1% of the scallop fishery productivity, hence it remains largely unaffected
  • There was a decline in cod fish discard from 100 tonnes in 2007 to 7.9 tonnes in 2018
  • There was a also a decline in yellowtail discard from 92 tonnes to 3.4 tonnes from 2007 to 2018
  • Has more industry support than dynamic ocean management

  • Relied on a close collaboration with industry and the development of a fleet communication system
  • Requires knowledge of the spatial and temporal dynamics of the resource being protected along with an understanding of the dynamics of the fishery being targeted by the closure
  • Lack of direct monitoring data
  • Closure duration is only based on peak spawning dates, not the entire spawning date
  • Lack of protection outside peak spawning date caused increase in bycatch and resulted in increased discards

  • Implementing time-area closures based on the life history of cod and yellowtail
  • Conducted by analyzing data from vessel monitoring system (VMS), fishery logbooks etc.

  • It was insufficient in reducing by-catch for both species. 
  • Neither closure had a significant impact on scallop fishery
  • Overall, there was an annual decline in discards/by-catch but it was not due to the closure
  • More research needs to be done to come out with improvements and alternative strategies

  • Scallop fisheries have closely followed the productivity of the scallop in spatial terms

    • Both cod and yellowtail habitat is located near or close to scallop productivity
    • Led to increase in bycatch when fishery efforts are high

  • Cod are located near the moderate scallop productivity area
  • Cod have spawning aggregation from November-may, peaking at February-March
  • 14.7% of scallop TAC was harvested when cod closure cells are active
  • Cod closure was active before peak scallop fishery
  • in other words, closure had little effect on fishery behavior

  • Generally in less productive areas of scallop
  • Spawning from April-August, peaking May-June
  • Closures are active when there is high fishing effort
  • Due to location, it had little impact on scallop fishery

    Example: The scallop fishery has established an informal voluntary move protocol in which vessels will move and inform their counterparts if they encounter unusually high groundfish by-catch in a particular area.]]>     2022-02-03 05:53:13 UTC https://padlet.com/200146891/zgivcmee72mqkcph/wish/2026849020     Closure dates https://padlet.com/200146891/zgivcmee72mqkcph/wish/2026853433 Cod closure dates: February to April
