Fish otoliths from the Pliocene Heraklion Basin (Crete Island, Eastern Mediterranean) [PDF]
The Pliocene Eastern Mediterranean fish record is revealed through the study of a 60-m thick stratigraphic sequence near the village Voutes (Heraklion, Crete). Forty-two species belonging to twenty families are identified.

ABSTRACT Harbor porpoises (Phocoena phocoena) are among the most widespread cetacean species in Irish waters and are listed under Annex II of the EU Habitats Directive as a species of community importance. The local harbor porpoise population in Dublin Bay coexists with designated spoil grounds for dredging activity, which has increased due to Dublin ...

Reproduction of cod, Gadus morhua (Actinopterygii: Gadiformes: Gadidae), from the Gdańsk Deep (Baltic Sea) under controlled conditions [PDF]
Background. The stocks of cod, Gadus morhua Linnaeus, 1758, have been declining within recent decades and the Baltic Sea is one of the most affected areas.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts
Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...

Linking Multiscalar Fisheries Using Metacoupling Models
Marine fisheries are social-ecological systems important for human health and livelihoods. However, research approaches that consider human–nature interactions within as well as between adjacent and distant fisheries are scarce.

The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea
ABSTRACT Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer‐term impacts of altered trophic interactions, yet it is rarely incorporated into marine policy frameworks.

Investigations on demersal fish in the Barents Sea winter 2006 [PDF]
A combined acoustic and bottom trawl survey to obtain indices of abundance and estimates of length and weight at age has been carried out each winter (4-6 weeks in January- March) since 1981 in the Barents Sea. The target species are cod and haddock, but

ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Fish community structure of the middle course of the Bečva River
Fish communities of the Bečva River were studied in summer and autumn 2000 and 2001. Electric fishing gear (Honda EX 1000, DC 230 V, 0.75-0.9 kW) was used for sampling. Four sampling sites (Grymov 19.6 r. km, Rybáře 35.8 r. km, Hustopeče 50.7 and Choryně
