Fisheries stock assessments
To get the most benefit from a fish stock in the long term, we need to maximise our yield without damaging the fish population we rely on. -
CASAL
CASAL is an advanced software package developed by NIWA for fish stock assessment. -
Environmental monitoring
NIWA collects a vast range of environmental information about New Zealand’s environment from the sky to the seafloor. -

Guidelines for sampling freshwater fisheries
We have prepared a breakdown of the different guidelines that are available for sampling freshwater fisheries. The overview provides links to key documents that explain what should be considered when designing fish monitoring studies and how to implement the various sampling techniques. -
Scholarships
Scholarships available to both Masters and undergraduate students in the fields of fisheries science and marine biology. -
Trawl fisheries bycatch
Accurate reporting on the amount of fish and invertebrates that are caught and discarded by New Zealand’s commercial fishing industry is vital to effective management of these fisheries. -
Biological limitations
Identifying biological factors that may be limiting fish numbers requires sampling to ensure that key invertebrate prey species are not scarce and that pest fish, especially predators, are not abundant. -
Estimated bycatch
View data that show reported target catch and estimated bycatch.
