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.

Emerging patterns of species richness, diversity, population density, and distribution in the skates (Rajidae) of Alaska [PDF]
, 2008 Six years of bottom-trawl survey data, including over 6000 trawls covering over 200 km2 of bottom area throughout Alaska’s subarctic marine waters, were analyzed for patterns in species richness, diversity, density, and distribution of skates. The Bering

The aesthetic sublime of megaproject structures: A framework and a research agenda
European Management Review, EarlyView.Abstract The physical structures of megaprojects—such as mega‐canals, metros, railway lines, bridges, tunnels, and iconic opera houses—hold a profound capacity to generate aesthetic experiences with enduring societal impact. Yet, research on megaprojects has predominantly focused on functionality and economic rationale with aesthetics being pushed to ...

Conservation Biology of Elasmobranchs [PDF]
, 1993 Elasmobranchs are vital and valuable components of the marine biota. From an ecological perspective they occupy the role of top predators within marine food webs, providing a regulatory control that helps balance the ecosystem.

Offspring Size Resolves a Population Growth Paradox in Rays and Skates
Fish and Fisheries, EarlyView.ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

Fisheries Management and Ecology, EarlyView.ABSTRACT In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey.

An Interdisciplinary Sustainability Evaluation of the Skate Fishery in the Gulf of Alaska [PDF]
, 2012 Skates are in growing demand worldwide, and the 2008 U.S. landings of skates was estimated at 65 million pounds, worth $11 million. However, many Atlantic Ocean skate stocks are collapsing.

Journal of Fish Biology, EarlyView.Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Biodiversity as an index of regime shift in the eastern Bering Sea [PDF]
, 2006 Data collected from an annual groundf ish survey of the eastern Bering Sea shelf from 1975 to 2002 were used to estimate biomass and biodiversity indexes for two fish guilds: f latfish and roundfish.

DNA barcoding unveils skate (Chondrichthyes: Rajidae) species diversity in ‘ray’ products sold across Ireland and the UK [PDF]
, 2013 Skates are widely consumed across the globe, but many large species are subject to considerable concern regarding their conservation and management. Within Europe such issues have recently driven policy changes so that, for the first time, reports of ...
