520 3# ‡aEvaluates five options for subdividing precautionary catch limit for krill in CCAMLR Area 48 among small-scale management units (SSMUs). Four options involve static allocations where allotment of catch to SSMU is proportional to either historical catch within SSMU; or estimated predator demand in SSMU; or estimated standing stock of krill in SSMU; or standing stock less predator demand in SSMU. Fifth option involves dynamic allocation based on land-based predator monitoring conducted just prior to, or early in, the fishing season. Under first two options substantial portion of catch limit would be allocated to SSMUs adjacent to large concentrations of land-breeding predators; under second two options similarly large portion of catch limit would be directed to pelagic SSMUs beyond foraging area of these predators but into areas where krill fishing has not regularly occurred. Under adjustable catch limit dependent on results of ecosystem monitoring exemplified by option five, fishery would be restricted in some of its traditional fishing grounds during years of low krill availability. Discusses possible future trade-off as catch increases between options that displace fishery from current operating area but reduce potential for contravening terms of Convention, and options that do not displace fishery but are likely to contravene terms of Convention.
