Refining Spat‐Collection Practices to Optimise Single‐Seed Spat Production for New Zealand's Greenshell (Perna canaliculus) Mussel Industry

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Mussel aquaculture depends on a consistent spat supply, often sourced from spat‐collection ropes suspended in coastal waters. However, settlement on these ropes can be highly variable due to environmental factors. Therefore, improving spat supply from this source relies on optimising aspects of the process, particularly the timing of ...

Review of bycatch mitigation measures in tuna longline fishery

NIPPON SUISAN GAKKAISHI, 2010
This review classiˆes and explains the bycatch mitigation measures in tuna longline ˆshery based on theirfunctional mechanism across bycatch species. In longline ˆshery bycatch mortality occurs through a commonprocess that typically follows these stages: 1) ˆshing operations overlap with the distribution of non-targetanimals; 2) non-target animals ...
