Reduced bait loss and bycatch of seabirds in longlining by using a seabird scarer
Abstract: Although longlining is regarded as a highly conservation oriented method of fishing ... , bycatch of seabirds on longlines is a problem in certain seasons and areas. Birds feeding on the bait ... eventually give high mortalities considering the large amounts of hooks used. Both from a fishery and bird ... conservation point of view there is a strong incentive to solve this problem. This paper describes trials with ...

Albatross mortality and associated bait loss in the Japanese longline fishery in the Southern Ocean
Abstract: A conservative calculation of the number of albatrosses killed annually on Japanese ... fishery alone exceeding $A 7 million. If all fish species and the total longlining effort were considered ... , it would be many millions of dollars greater. Apart from a concern for albatrosses, Japan's ... longline fishermen would also benefit by using the solutions offered. It is suggested that a 70% reduction ...
