Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Reproduction Traits and Strategies of Two Sardinella Species off the Southwest Coast of Africa

open access: yesFishes
Small pelagic fishes such as Sardinella aurita (Valenciennes, 1847) and Sardinella maderensis (R. T. Lowe, 1838) are key intermediate-level components of the marine food web of the southwestern African coast.

Projected Future of African Marine Ecosystems Under Climate Change and Stratospheric Aerosol Injection

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Stratospheric Aerosol Injection (SAI) has been proposed as a potential strategy to cool the planet. The ARISE‐SAI‐1.5 approach, which employes a moderate emission scenario, is simulated to limit future global warming to 1.5°C by injecting aerosols into the stratosphere in the year 2035.

Refining a molecular tool kit to capture tropicalization in Mediterranean marine protected areas

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
We assess complementarity and trade‐offs between visual census and eDNA metabarcoding for monitoring fish community changes in MPAs. Abstract Tropicalization, the process by which tropical species expand their ranges poleward due to global ocean warming, is a prominent threat to Mediterranean marine ecosystems, challenging their effective management ...

Reproductive Biology of Round Sardinella (Sardinella Aurita) (Valenciennes, 1847) in Senegalese Coastal Waters

open access: yesJournal of Biology and Life Science, 2018
In this study, a total of 1068 specimens Sardinella aurita of which 553 females and 515 males were examined. The objectif of this study was to determine the reproductive parameters of Sardinella aurita. The sex ratio was significantly in favor of females (55%). The size at first sexual maturity was estimated at 18.9 cm for females and 18.0 cm for males.

Rôle possible d'une intensification des alizés sur le changement de répartition des sardines et sardinelles le long de la côte ouest africaine [PDF]

open access: yes, 1987
Jusqu'aux dernières décennies on considérait que la limite de répartition entre sardines et sardinelles se situait aux environs du Cap Blanc. Au nord de ce cap, les remontées d'eaux ont lieu toute l'année, la production primaire est forte, mais non la ...

Estimating European Pilchard (Sardina pilchardus) Total Length: New Equations for the Ichthyoarchaeological Record

open access: yesInternational Journal of Osteoarchaeology, Volume 36, Issue 2, Page 325-340, March/April 2026.
ABSTRACT Throughout its area of distribution, in particular in the Iberian Peninsula, the European pilchard (Sardina pilchardus Walbaum 1792) has been an extensively exploited species since Prehistoric times. Our knowledge of the past fisheries of this clupeid nevertheless remains limited due to a scarcity of ichthyoarchaeological data, which reflects,
