Flashing NetLights reduce bycatch in small-scale fisheries of the Eastern Mediterranean

Submitted by twerner on

Illuminated nets were tested to evaluate their effect on catch and bycatch in set nets, principally green and loggerhead sea turtles, in northern Cyprus. Reductions in the catch of sea turtle and non-target sharks and rays were recorded with no effect on target catch. Data were collected from 130 field sets thst occurred over a two-year period. Experimental effort should be expanded to better ascertain the relationship between the illuminated devices used and sea turtle bycatch reduction.

Effectiveness of mitigation measures to reduce interactions between commercial fishing gear and whales

Submitted by allykristan on

Surveys and data sources were used to investigate overlap of migrating humpback whales and both the Western Rock Lobster Fisheries and Developmental Octopus Fisheries off the coast of Western Australia, and to investigate gear modifications to mitigate entanglement. Modifications were made to float rigs (rope type, rope length, and number of floats used), but effectiveness was not assessed within this project. Preliminary results showed that whales are more likely to become entangled in ropes that are thinner, mainlines that are yellow or orange, and orange header rigs.

Killer whale (Orcinus orca) interactions with blue-eye trevalla (Hyperoglyphe antarctica) longline fisheries

Submitted by allykristan on

This study assessed the frequency and spatio-temporal variation of previously unreported killer whale interactions/depredation with blue-eye trevalla (Hyperoglyphe antarctica) longline fisheries in two geographically isolated populations: one off Amsterdam/St. Paul Islands and another in south-eastern Australia. This two fisheries differ in fishing technique (vertical vs. demersal longlines) and effort.
