Among-year variation in growth of Antarctic krill Euphausia superba based on length-frequency data [PDF]
Marine Ecology Progress Series, 2013 Understanding the temporal variability in vital rates (e.g. growth and survivorship) of wild populations is practically and statistically difficult but crucial for connecting such variation to mechanistic drivers and their population consequences. For somatic growth, empirical estimates of variation are rare because they often require expensive long ...

TropFishR: an R package for fisheries analysis with length-frequency data
, 2016 1. The R package TropFishR is a new analysis toolbox compiling traditional and advanced single-species stock assessment methods for the analysis of small-scale and data-poor fisheries.2. It includes functions for (i) estimating biological stock characteristics such as growth and mortality parameters, (ii) exploring technical aspects of the fisheries (e.

Precision estimates and suggested sample sizes for length-frequency data
, 2007 For most fisheries applications, the shape of a length-frequency distribution is much more important than its mean length or variance. This makes it difficult to evaluate at which point a sample size is adequate. By estimating the coefficient of variation of the counts in each length class and taking a weighted mean of these, a measure of precision was

Journal of New Results in Science, 2020 : The growth parameters of whiting (M. merlangus euxinus, N. 1840) were estimated using length frequency data collected by trawl fishing in the Sinop region, Turkey during September 2009 to April 2010.

Updated catch length frequencies for the Tristan group of islands using factory pack category data
, 2011 Reliable factory processing records of lobsters caught at all four islands of the Tristan group are available since 20011 . These “pack category” data record the number of lobsters that fall into different packing categories. There are two types of product for which data have been collected: “tails” (where only the tails are packed into cartons) and ...
