Indirect effects of conservation policies on the coupled human-natural ecosystem of the upper Gulf of California. [PDF]
PLoS ONE, 2013 High bycatch of non-target species and species of conservation concern often drives the implementation of fisheries policies. However, species- or fishery-specific policies may lead to indirect consequences, positive or negative, for other species or ...

Re-identification of fish individuals of undulate skate via deep learning within a few-shot context
Ecological Informatics, 2023 Individual re-identification is critical to track population changes in order to assess status, being particularly relevant in species with conservation concerns and difficult access like marine organisms. For this, we propose photo-identification via deep learning as a non-invasive technique to discriminate between individuals of the undulate skate ...

Journal of Northwest Atlantic Fishery Science, 2022 We re-analyze Thorny skate data from two comparative fishing experiments conducted by DFO in 1995 and 1996 using improved and more contemporary methods to estimate the relative efficiency of the Campelen 1800 demersal shrimp trawl survey protocol compared to the Engel 145 otter trawl.

Fifty years of tagging skates (Rajidae): using mark-recapture data to evaluate stock units [PDF]
, 2020 Despite increased focus on ascertaining the status of elasmobranch fish, the stock units for many species are uncertain. Data from mark-recapture tagging studies undertaken from 1959–2017 were analysed for 13 batoid species.

Survey sequencing and comparative analysis of the elephant shark (Callorhinchus milii) genome.
PLoS Biology, 2007 Owing to their phylogenetic position, cartilaginous fishes (sharks, rays, skates, and chimaeras) provide a critical reference for our understanding of vertebrate genome evolution.

Comparative genomics of chondrichthyan Hoxa clusters
BMC Evolutionary Biology, 2009 Background The chondrichthyan or cartilaginous fish (chimeras, sharks, skates and rays) occupy an important phylogenetic position as the sister group to all other jawed vertebrates and as an early lineage to diverge from the vertebrate lineage following ...

Commercial catches, reproduction and feeding habits of Raja asterias (Chondrichthyes: Rajidae) in a coastal area of the Tyrrhenian Sea (Italy, northern Mediterranean) [PDF]
Acta Adriatica, 2007 A total of 52 “rapido” (towed toothed beam gears) trawls were monitored in late winter-summer of the 1999-2000 period to assess the R. asterias size structure at this time of higher yields as well as 36 fishing operations performed by “volantina” (trawl ...

Fishing characters of skate ray, Raja pulchra by the offshore longline fishery in Heuksan-do, Korea [PDF]
Bulletin of the Korean society of Fisheries Technology, 2011 Catches, CPUE, fishing season, disc width composition and fishing ground were studied to rebuild skate ray, Raja pulchra resource by the offshore longline fishery in Heuksan-do, Korea. Annual catches and CPUE of skate ray were increased from 2003 to 2010 (CPUE: from 2007 to 2010) continuously.
