Detection heterogeneity in underwater visual‐census data
Journal of Fish Biology, 2008 This study shows how capture–mark–recapture (CMR) models can provide robust estimates of detection heterogeneity (sources of bias) in underwater visual‐census data. Detection biases among observers and fish family groups were consistent between fished and unfished reef sites in Kenya, even when the overall level of detection declined between locations.

Optimising sampling of fish assemblages on intertidal reefs using remote underwater video [PDF]
PeerJ, 2023 Background Assessing fish assemblages in subtidal and intertidal habitats is challenging due to the structural complexity of many of these systems. Trapping and collecting are regarded as optimal ways to sample these assemblages, but this method is ...

Local ecological knowledge and scientific data reveal overexploitation by multigear artisanal fisheries in the southwestern Atlantic. [PDF]
PLoS ONE, 2014 In the last decades, a number of studies based on historical records revealed the diversity loss in the oceans and human-induced changes to marine ecosystems. These studies have improved our understanding of the human impacts in the oceans.

Environmental DNA helps reveal reef shark distribution across a remote archipelago
Ecological Indicators, 2023 Environmental DNA (eDNA) methods are being increasingly used in proof-of-concept studies to detect shark species, many populations of which are experiencing severe declines. These methods are widely seen as the future of biodiversity monitoring, but they

The condition of megabenthos and reef fish in coral reef ecosystems in Aru Islands National Conservation Area, Southeast Maluku, Indonesia [PDF]
E3S Web of Conferences, 2023 The waters of the Aru Islands are part of the National Marine Protected Areas (MNR), and have extensive coral reefs with high biodiversity. The study was conducted in October 2016 at twelve stations to determine the status of coral cover, composition ...

Tropical marine fish from Celukan Bawang Port, Buleleng, Bali, Indonesia [PDF]
E3S Web of Conferences, 2021 Celukan Bawang port is located in Buleleng Regency, Bali, Indonesia. The area of Celukan Bawang Port has a coral reef ecosystem that is very rarely found in Indonesian ports. The coral reef has an important role for coral reef fish as their habitat. This

Seasonal changes in fish assemblage structure at a shallow seamount in the Gulf of California [PDF]
PeerJ, 2016 Seamounts have generally been identified as locations that can promote elevated productivity, biomass and predator biodiversity. These properties attract seamount-associated fisheries where elevated harvests can be obtained relative to surrounding areas.

Effect of underwater visual survey methodology on bias and precision of fish counts: a simulation approach [PDF]
PeerJ, 2018 Bias in underwater visual census has always been elusive. In fact, the choice of sampling method and the behavioural traits of fish are two of the most important factors affecting bias, but they are still treated separately, which leads to arbitrarily ...
