Fishing mortality rates for the major targeted and byproduct species of sharks landed by the Queensland East Coast Inshore Fin Fish Fishery (ECIFFF) have been estimated. The effects of these fishing mortality rates on population persistence for these species have also been modelled with demographic...
The need to optimise spawning success and survival of offspring by fishes has resulted in the evolution of a vast array of reproductive strategies, such as spawning aggregations. A spawning aggregation is defined by Domeier and Colin (1997) as, “a group of con-specific fish gathered for the...
The project outputs have led to the following outcomes:
1. A model has been developed enabling reliable estimation of mortality of fish species that undertake size-related, unidirectional, offshore movements from age and length data. This new modelling approach is likely to be applicable to stocks...
