Abstract:
... Acoustic scattering layers (SL) at various depths are common phenomena in most oceans, but the organisms that make up these layers vary and so does their density, and hence the backscattered energy. During two crossings of the deep Fram Strait between the shelves at Svalbard and Northeast Greenland at latitudes 77°N and 79°N, we registered epipelagic and mesopelagic SL across the entire Fram Strai ...

Abstract:
... A challenge for the aquaculture community has long been the development of harmless techniques for monitoring fish in a tank. Acoustic telemetry has been used to monitor fish swimming behavior, and passive acoustics have been used to monitor fish feeding, but new techniques are needed to monitor non-invasively their numbers and growth rates. Recently, it has been demonstrated that the acoustical t ...

Abstract:
... The genetic underpinnings that contribute to ecological adaptation and speciation are not completely understood, especially within marine ecosystems. These evolutionary processes can be elucidated by studying adaptive radiations, because they provide replicates of divergence within a given environment or time-frame. Marine rockfishes (genus Sebastes) are an adaptive radiation and unique model syst ...

The reproductive modes of the Scorpaenidae are extremely varied: oviparity, viviparity, and even spawning of internally fertilized eggs or embryos (zygoparity or embryoparity), as in Helicolenus, are known. The ovarian structure of this family is divided into two types by the arrangement of the stroma and the ovarian cavity. One type is the ovary in which the lamella-like stroma develops from the ...

Abstract:
... Multispecies modeling is being increasingly accepted in stock assessment, especially in the context of an ecosystem approach to fisheries management (EAF). To achieve a future implementation of an EAF in the Flemish Cap, we present a multispecies model developed in Gadget, which covers the main commercial stocks over the period 1988–2012: cod (Gadus morhua), redfish (Sebastes spp.), and northern s ...

Abstract:
... A parasite assemblage of Sebastes miniatus from northwestern Baja California, México, was composed of a total of 12 species: five ectoparasites (two monogeneans and three parasitic copepods) and seven endoparasites (two digeneans, one cestode, three nematodes, and one acanthocephala). Five of these parasites constituted new genera records to the genus Sebastes, and nine were new geographic records ...

One of the disquieting consequences of fishing is reduction in the mean trophic level of commercially captured species (fishing down the food web). While the trophic level of fisheries catch has declined in nearly two-thirds of the world's ecosyst ...

Abstract:
... Global warming drives changes in oceanographic conditions in the Arctic Ocean and the adjacent continental slopes. This may result in favourable conditions for increased biological production in waters at the northern continental shelves. However, production in the central Arctic Ocean will continue to be limited by the amount of light and by vertical stratification reducing nutrient availability. ...

Abstract:
... Genetic and morphological divergence among the four subspecies in the Sebastes pachycephalus complex (S. pachycephalus pachycephalus, S. p. nigricans, S. p. nudus and S. p. chalcogrammus) was clarified. Principal coordinate analysis (PCoA) based on AFLP clearly divided 55 specimens of the complex into two groups, the S. p. pachycephalus–S. p. nigricans group (P-Ni group) and the S. p. nudus–S. ...

Abstract:
... The genetic differences among three colour morphotypes of the black rockish, Sebastes inermis, were determined from mitochondrial DNA (mtDNA) and amplified fragment length polymorphisms (AFLP) analyses. In the AFLP analysis, each morphotype could be distinguished by the presence or absence matrix of five AFLP loci. These diagnostic loci indicated that the three morphotypes represented independent ...

Abstract:
... Rockfishes of the genus Sebastes are extensively distributed in the Pacific and Atlantic oceans. Although the occurrence of two morphologically similar species in the Southern Hemisphere, Sebastes oculatus and Sebastes capensis, is now clearly established, the taxonomic status and phylogeographic patterns for the genus in the region have not yet been completely resolved. In this study, we provide ...

Abstract:
... Prevailing oceanographic processes, pelagic larvae, adult mobility, and large populations of many marine species often leads to the assumption of wide-ranging populations. Applying this assumption to more localized populations can lead to inappropriate conservation measures. The Pacific ocean perch (Sebastes alutus, POP) is economically and ecologically valuable, but little is known about its popu ...

Abstract:

A field experiment was conducted for 4 consecutive days in December 2010 in Hornopirén inlet, a fjord from Chilean Patagonia, in order to determine the impact of marked environmental differences on fish larval distribution and growth (i.e., otolith microstructure) of the rockfish Sebastes oculatus. Two layers were noticeable: a surface one (0–10 m depth), characterized by warmer temperature and lo ...

Abstract:
... Nursery areas for juvenile fishes are often important for determining recruitment in marine populations by providing habitats that can maximize growth and thereby minimize mortality. Pacific ocean perch (POP, Sebastes alutus) have an extended juvenile period where they inhabit rocky nursery habitats. We examined POP nursery areas to link growth potential to recruitment. Juvenile POP were captured ...

Abstract:
... The present study evaluates the extent to which the viviparous reproductive strategy that characterizes the genus Sebastes (rockfish) can be expressed in culture. In addition, the growth patterns of rockfish were examined during the early phases of growth pertinent to the culture of the species. Using grass rockfish (Sebastes rastrelliger) as our model, it was demonstrated that all phases of ovari ...

Abstract:
... For species that have an open population structure, local population size may be strongly influenced by a combination of propagule supply and post‐settlement survival. While it is widely recognized that supply of larvae (or recruits) is variable and that variable recruitment may affect the relative contribution of pre‐ and post‐settlement factors, less effort has been made to quantify how variatio ...

We combined a high-resolution acoustic telemetry array with presence/absence receivers to conduct a preliminary study of the seasonal movements, activity patterns, and habitat associations of the newly described Deacon Rockfish (Sebastes diaconus). Eleven mature female Deacon Rockfish were tagged and monitored during an 11-month period, at a nearshore rocky reef off Seal Rock, Oregon, USA, an area ...
