5. Fish Heaven: a Monte Carlo, spatially explicit single species fishery model for the testing of parameter estimation methods

   Abstract:  Fish Heaven is a simple spatially explicit age structured fish model, containing the ... basic features of standard fish modeling with a number of optional extras. It was designed within an ... object oriented framework to allow for the possible extension in a number of directions. In particular it ... various plausible spatial structures of fish stock.

6. 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 ...
