Ewing, G and Keane, JP and Semmens, JM, Industry-independent video survey of commercial scallop (Pecten fumatus) densities in Great Oyster Bay - May 2017 survey, Institute for Marine and Antarctic Studies, University of Tasmania, Hobart, Tasmania, June (2018) [Government or Industry Research]
A concurrent towed video survey of recreational scallops in the D’Entrecasteaux Channel, which allowed direct comparison with quantitative diver transect methods, indicated a high level of accuracy in scallop density estimates from towed video footage. Comparisons of size structure indicated some bias in the video derived data, in particular in defining the cohort structure in the smaller size classes.
The towed video proved to be a very-cost effective and low impact technique for the rapid assessment of scallop abundance, provides an indication of relative size structure, and hence is an effective methodology for fishery-independent biomass estimation.
