First steps towards mass rearing of European smelt (Osmerus eperlanus, L.) using conventional hatchery equipment

Aquatic Living Resources, 2023
Anadromous European smelt (Osmerus eperlanus) is a keystone species in lake and river ecosystems. In the past and present, stock declines in several of its habitats have been reported. The reasons for this are unclear.

Effects of bottom trawling on fish foraging and feeding [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2015
The effects of bottom trawling on benthic invertebrates include reductions of biomass, diversity and body size. These changes may negatively affect prey availability for demersal fishes, potentially leading to reduced food intake, body condition and yield of fishes in chronically trawled areas.

Aquaculture Impacts on China’s Marine Wild Fisheries Over the Past 30 Years

Frontiers in Marine Science, 2021
China is the world’s largest producer of aquaculture and capture fisheries. How this country develops its aquaculture sector and whether such development can relieve pressure on wild fisheries remain a contentious issue in the past and for the future ...

Assessing the reliability of species distribution models in the face of climate and ecosystem regime shifts: Small pelagic fishes in the California Current System

Frontiers in Marine Science, 2022
Species distribution models (SDMs) are a commonly used tool, which when combined with earth system models (ESMs), can project changes in organismal occurrence, abundance, and phenology under climate change.

Comparative analysis of IGFBP-3 gene sequence in Egyptian sheep, cattle, and buffalo

BMC Research Notes, 2019
Objective A total of 205 animals from four Egyptian livestock species; cattle (n = 18), buffaloes (n = 12), sheep (n = 150) and goats (n = 25) were used in this study to detect polymorphism and perform comparative analysis for IGFBP-3 gene using DNA ...

First-Year Survival of Northern Fur Seals (Callorhinus ursinus) Can Be Explained by Pollock (Gadus chalcogrammus) Catches in the Eastern Bering Sea

Journal of Marine Science and Engineering, 2021
The Pribilof northern fur seal (Callorhinus ursinus) herd in the eastern Bering Sea has declined by ~70% since the 1970s, for elusive reasons. Competition for pollock (Gadus chalcogramma) with the commercial fishery has been suspected as a contributing ...

Extreme mortality and reproductive failure of common murres resulting from the northeast Pacific marine heatwave of 2014-2016.

PLoS ONE, 2020
About 62,000 dead or dying common murres (Uria aalge), the trophically dominant fish-eating seabird of the North Pacific, washed ashore between summer 2015 and spring 2016 on beaches from California to Alaska.

The Path to an Ecosystem Approach for Forage Fish Management: A Case Study of Atlantic Menhaden

Frontiers in Marine Science, 2021
Atlantic menhaden (Brevoortia tyrannus) support the largest fishery by volume on the United States East Coast, while also playing an important role as a forage species. Managers’ and stakeholders’ increasing concerns about the impact of Atlantic menhaden

Dimethylsulfoniopropionate as a Foraging Cue for Reef Fishes

Science, 2008
Coral reefs resemble islands of productive habitats where fishes aggregate, forage, and spawn. Although it has been suggested that some reef fishes use biogenic chemicals as aggregation cues, specific chemicals have not been identified. Dimethylsulfoniopropionate (DMSP), a secondary metabolite of many marine algal species, is released during foraging ...
