Stochastic Modelling to Assess External Environmental Drivers of Atlantic Chub Mackerel Population Dynamics

open access: yesSustainability, 2022
The population dynamics of small and middle-sized pelagic fish are subject to considerable interannual and interdecadal fluctuations in response to fishing pressure and natural factors. However, the impact of environmental forcing on these stocks is not well documented.

Stochastic surplus production and length-based assessment models to compare Maximum Sustainable Yield advice for the Moroccan Atlantic chub mackerel

open access: yesFrontiers in Marine Science
Fisheries management needs to ensure that resources are exploited sustainably and the risk of depletion is at an acceptable level. In developing countries, multi-gear, multispecies fisheries often lack data, making conventional stock assessment ...

Fecundity of Scomber (Actinopteri: Scombridae) Species Distributed in Izmir Bay (Aegean Sea)

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
A total of 46 chub mackerel and 23 Atlantic mackerel samples were taken from the commercial fishermen engaged in purse seine fishing from the Izmir Bay during the fishing period of 2020-2021.

Global Marine Fishery Stock Productivity Under Climate Change. [PDF]

open access: yesGlob Chang Biol
In this uniquely extensive global analysis on the productivity of commercial fishery stocks, a common factor was the existence of pronounced heterogeneity, as documented for 710 stocks in the undertaken hindcast over the last decades. Importantly, both winners and losers appear under on‐going climate change, and then seemingly are equally present ...

Second Workshop on Atlantic chub mackerel (Scomber colias) (WKCOLIAS2) [PDF]

open access: yes, 2021
The Atlantic chub mackerel Scomber colias has become an increasingly important commercial species in the European Atlantic waters in the last 10–15 years, probably through an expansion process from NW African waters and due to market needs. However, at present there are no assessment or advice requirements. In the WK framework, available information of

Microplastic ingestion and diet composition of planktivorous fish

open access: yesLimnology and Oceanography Letters, 2020
Planktivorous pelagic fish are susceptible to accumulating microplastics (MP), which have the same size range as their prey and accumulate in their feeding and spawning grounds.

Emerging Perspectives on Gonadotropin Regulation in Vertebrates Revealed by the Discovery of FSH-RH in Teleosts. [PDF]

open access: yesBioessays
Regarding pituitary gonadotropin regulation, recent studies have shown that in mammals, FSH and LH are regulated by a single GnRH (solo GnRH model), whereas in teleosts, they are regulated by CCK (FSH‐RH) and GnRH (LH‐RH), respectively (dual GnRH model).

Fishing areas characterisation using the SIMOcean platform

open access: yesAquatic Living Resources, 2017
In this study, the relationships between sea surface temperature (SST), chlorophyll-a (Chl-a) concentration and catch locations of sardine (Sardina pilchardus) and Atlantic chub mackerel (Scomber colias) were explored using satellite-derived SST and Chl ...

Mitigating slipping-related mortality from purse seine fisheries for small pelagic fish: case studies from European Atlantic waters [PDF]

open access: yes, 2019
The release of unwanted catches (UWC) from purse seines, while the catch is still in the water, is known as “slipping”. Once thought to be a benign process, compared to discarding UWC overboard from the fishing vessel, it is now recognised that “slipping”

Optimal Strouhal number for swimming animals [PDF]

open access: yes, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.
