Assessing data requirements for tag-based estimates of local biomass in data-poor and exploratory fisheries
Abstract: This study used an operating model to simulate a Dissostichus eleginoides population in ... Research Block 5843a_1 with a fixed exploitation rate and various tagging rate scenarios to assess the ... estimator. The results showed that tag-based biomass estimates obtained from a low numbers of recaptures ... will have a high risk of over-estimating biomass and that for a given number of tagged fish available a ...

Defining fishing grounds in the Scotia Sea
Abstract: This paper provides a method for delineating krill fishing grounds in Area 48 based on ... relationship between the fishing grounds and the krill population. We define a fishing ground as being a ... predictable location where the fishery obtains relatively reliable catches from one year to the next over a ... number of years. The quantity of interest is not only the total catch obtained from a location, say a 10 ...

Spatial variability and power to detect regional-scale trends
of variation in a system, resulting in low power in trend detection across that scale, despite ... examined, monitoring at only 2 or 3 sites provided insufficient power to detect a trend. At the other ... extreme, monitoring at all sites in a region (a census) may be an unnecessary use of resources because the ... gains in power over a design using a sample of sites were very marginal. Reasonable power was achieved ...

Tests for anomalous years in the CCAMLR index series (draft)
Abstract: The properties of a method for detecting anomalous years in CCAMLR index series are ... discussed. In simple cases this method involves comparing a standardized residual with a critical value ... obtained on the assumption that the series being considered consists of random values from a constant ... normal distribution. This idea is extended to situations (a) where the series values are still normally ...

Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
for Patagonian toothfish around Heard Island (Division 58.5.2) was modelled as the exponential of a ... length classes as a function of fishing depth, a log-linear hazard function for each gear type was fitted ... by a technique used to model grouped survival data. The hazard function relates to the event of a ... fish falling in a particular length bin, analagous to a death in a given time interval in survival ...
