Only 25% of deepwater trawlers in New Zealand have government observers onboard to record by-catch
and discards, according to the National Institute of Water and Atmospheric Research [Niwa], which relies on statistical modelling techniques to generate by-catch
estimates for the 75% of boats that work unobserved.
A larger mesh size means there is less by-catch
of other non-targeted species, mostly because they are too small to get caught, and also no harvest of juvenile fish stocks.
This project took advantage of the naturally occurring foraging behavior of bottlenose dolphins described by Svane (2005) associated with by-catch

For the last three years the guides in the Icelandic river I fish every August have been blaming on the high seas netting of smolts and post smolts as an accidental by-catch

But that downward trend could be reversed by overhauling fisheries management, protecting fish spawning and breeding habitat and reducing by-catch
(the incidental catch of species not targeted by fishermen).
Campaigners say the nets - a method of fishing known as purse-seining - scoop up other species as well as tuna, which are then killed as by-catch
management measures to eliminate overfishing, prevent illegal fishing, and minimise by-catch
Members from the society also had the opportunity to meet with the top officials and local fishermen to discuss ways on reducing the by-catch

Haider said in his speech during the workshop organized by PAFR and with cooperation of the Food and Agriculture Organization of the United Nations (FAO), on reducing the negative impact of by-catch
It also sets down recommendations for policymakers ranging from defining objectives, targets, harvest control rules and assessment indicators to taking into account by-catch
Committed to sustainability, Aker Bio-Marine employs its proprietary Eco-Har-vesting technology, which results in almost total elimination of by-catch
and other environmental impacts.
