Description

An yearlong study to evaluate the potential of new management strategies directed to support the sustainable fishery of cuttlefish in the English Channel has been conducted by UoB, Sussex IFCA and Hastings fishers.
The ability of eggs dislocated from cuttle traps to develop and hatch under different laboratory conditions was tested. All laboratory experiments were designed to replicate environmental conditions at the time of egg deposition and development (substrate, water temperature, light regime). The analysis of egg diameter distribution showed high variations between egg size, suggesting either different laying events or a mixture of younger and older females spawning at the same time. This study combining laboratory experiments and first hand data recording has the potential to offer solid information regarding reproduction success and hatching in eggs dislocated from artisanal traps, and to contribute to the recovery of cuttlefish stocks in the framework of a broader management plan.
