Human observation is expensive and limits the breadth of data collection. For this reason,
remotely placed video cameras are increasingly used to monitor animals. One drawback of …

Tropical marine ecosystems are highly biodiverse and provide resources for small-scale
fisheries and tourism. However, precise information on fish spatial distribution is lacking …

This study aimed to add light-avoidance as a categorizing technique for the study of
mesopelagic acoustic layers. Data recorded along the 20° W parallel from 20° N to Iceland …

Micronekton distributions and assemblages were investigated at two shallow seamounts of
the south-western Indian Ocean using a combination of trawl data and a multi-frequency …

Fisheries acoustics surveys are effective tools in marine resource assessment and marine
ecology. Significant advances have occurred in recent years with the application of multiple …

Abstract Fish Target Strength (TS) is a requirement for estimating abundance from surveys of
pelagic fish using echosounders. This paper describes a novel in-situ method to estimate TS …

A small number of stationary echo sounders have the potential to produce abundance
indices where fish repeatedly occupy localized areas (eg, spawning grounds). To …

It is often assumed that in situ target strength (TS) measurements from dispersed fish are
representative of the surveyed schooling fish. For in situ TS measurements of orange roughy …

With the development of ocean exploration technology and the rapid growth in the amount of
marine science observation data, people are faced with a great challenge to identify …
