Following after them ... , with stomach often full of them, they became large, so the numbers of small individuals are ... get warmer.

Observer coverage required for the prediction of incidental capture of seabirds in New Zealand commercial fisheries
numbers of incidental seabird captures (albatross and petrel taxa combined) in a fishery with a specified ... contribution from the correlation between the numbers of captures per tow/set by the same vessel to be included ... . The model also permits the estimation of the contribution from the extra variation that arises from ... . Estimates of the variance components were derived from models that were fitted using data from the 1999–00 ...

Modelling the predator–prey interactions of krill, baleen whales and seals in the Antarctic ecosystem
that has become available since the postulate was first advanced is discussed. The objective of the ... and the assumptions on which they are based is discussed, together with suggested further areas for ... investigation. Amongst the key inferences of the study are that: i) species interaction effects alone can ... consider other species in addition to baleen whales and krill only to explain observed trends, with ...

Among all deterrents tested, paired streamer lines proved to be ... adjustment as physical conditions changed. Functionally, paired streamer lines created a moving fence that ... precluded seabird attacks. Most significantly, this success came with no consequence to catch rates of ...

Spatial scales of benthic invertebrate habitats from fishery by catch and video transect data in the Ross Sea region
these data allows the detectability of sponges and gorgonian corals to be estimated, along with changes ... collected for two fishing seasons, with 4728 longline segments observed. Several regions with consistent ... with no evidence of sponge or gorgonian presence. Identifiable sponge and/or gorgonian habitats ... in catch rate at different densities. Results indicate that sponge patches are detected more than 70 ...

Variability of krill fishery operations in Subarea 48.2 in relation to fishing methods: spatial–temporal distribution of CPUE and of fishing efforts
in Subarea 48.2 with special attention to the period 2006-2011 which is characterized by the highest ... fishing methods. It was shown how fishery operated by years and month in each SSMUs with special attention ... to differences between national fleets. Our results provide the evidence that ‘high CPUE’ regime’ in ... 2006-2011 is not associated with the changes in fishing methods and the trend in long-term fishery in ...

An ecological risk assessment of current conservation measures for krill fishing in East Antarctica (CCAMLR Divisions 58.4.1 and 58.4.2)
measures that are relevant to Divisions 58.4.1 and 58.4.2 sufficiently mitigate the risk of a krill fishery ... disproportionately concentrating catches in areas that are also important to krill predators. In particular, this ... , crabeater seals and Adélie penguins, in parallel with the currently agreed krill biomass estimates across ... assessment found the regional risk of the current conservation measures in Divisions 58.4.1 and 58.4.2 to be ...
