Wild fish aggregate at aquaculture net-pens, but the underlying mechanisms are not fully understood. This study examined how salmon farms attract coastal Atlantic cod Gadus morhua from their inshore spawning grounds. Acoustic receivers were deployed 5 known grounds and 6 Salmo salar located varying distances these in a mid-Norway site. Cod caught each ground annually 2017-2019, fitted with acou...

Abstract The blue and red shrimp Aristeus antennatus has been intensively exploited by trawling fishery in the Western Mediterranean Sea. Implementation of an adequate management plan needs complete genetic data non-spawning spawning grounds species. During reproductive period, species forms aggregations middle slope, mainly constituted mature females carrying spermatophores. Seven females’ Sea...

The article presents data on the fishery significance of Kizlyar and Agrakhan bays. Based results conducted researches, an assessment current state bays recommendations need for ongoing capital reclamation works to preserve natural spawning grounds passing semi-passing fish species are given.

Abstract The inshore commercial squids, Loligo vulgaris and L. forbesii, co-occur in the ecoregions of Celtic Seas Greater North Sea but spatio-temporal structure their spawning ranges is poorly understood. To help solve problem, data sets collected during last 30 years by British, German, French, Irish scientists, as well observations from multinational Citizen Science, were combined. Spawning...

The high productivity stems from the annual inundation by the Mekong River of the large floodplains found in central Cambodia around the Great Lake, Tonle Sap, and the Mekong floodplains northeast and south of Phnom Penh, where important fish habitats such as flood forests are found (Figures 1.1 and 1.2 page 16). Huge seasonal migrations take place between these floodplains and spawning grounds...

There is increasing recognition of intraspecific diversity and population structure within marine fish species, yet there is little direct evidence of the isolating mechanisms that maintain it or documentation of its ecological extent. We analyzed depth and temperature histories collected by electronic data storage tags retrieved from 104 Atlantic cod at liberty ≥1 year to evaluate a possible i...

The reproductive status and body condition of 195 (‡185 cm curved fork length, CFL; assigned age 7 and above) Atlantic bluefin tuna were assessed in the Gulf of Maine during the commercial fishing season of June– October, 2000–2002. Given the distance between known spawning and feeding grounds, the prevailing paradigm for Atlantic bluefin tuna (Thunnus thynnus thynnus, L.) suggests that the mos...
