Studying of <i>Trachurus trachurus</i> (Linnaeus, 1758) Population Reproductive Dynamics in the Eastern Moroccan Mediterranean. [PDF]

Ecol Evol
Horse mackerel (Trachurus trachurus) populations along the eastern Moroccan Mediterranean coast were studied over 12 months using 390 specimens to assess reproductive ecology. The species showed two spawning periods—late winter to early spring and summer—and exhibited fractional spawning, with males being more predominant.

Cities at Sea: Coastal Urbanization Generates Local Biodiversity Hotspots but Homogenizes Marine Fish Communities Regionally. [PDF]

Glob Chang Biol
We investigated whether coastal urbanization drives marine communities toward greater similarity, a process well‐documented as urban biotic homogenization in terrestrial and freshwater ecosystems but largely unexplored in the marine realm. From seawater environmental DNA samples collected along the French Mediterranean coastline targeting fish ...

Biological aspects and population dynamics of the European pilchard Sardina pilchardus (Walbaum, 1792) in the southeastern Mediterranean waters. [PDF]

J Fish Biol
Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

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

Glob 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 ...

Evaluation of the Nutritional Quality of the Five Commercial Fish Species From the Persian Gulf From Human Health Perspective. [PDF]

Food Sci Nutr
Based on the findings of this study, the best protein quality related to N. japonicus with an EAA index of 75.92. P. indicus has the best lipid quality due to the high ratio of ω‐3/ω‐6 (1.68) and PI (7.02). The abundant trace elements in all five fish species, K, Ca, Fe, and Zn, as well as these fish species, have good nutritional quality based on Na/K
