Effect of Poor Handling on the Nutritional Composition of Some Imported Frozen Fishes in Nigeria

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2015
This study aimed to determine and compare proximate composition of three commonly commercial imported frozen fish species in Nigeria (Scromber scrombrus, Trachurus  trachurus and Sardinella aurita) with reference to poor handling and size. Major nutrient

Connecting sea to market: Using network analysis to understand social–ecological dynamics in seafood value chains in Pisco, Southern Peru

open access: yesPeople and Nature, Volume 7, Issue 10, Page 2465-2485, October 2025.
Abstract Small‐scale fisheries represent complex human‐nature interactions, targeting different species in different locations throughout the year. On land, fishers are at the core of diverse seafood value chains that serve local and distant markets.

Genetic analysis provides insights into species distribution and population structure in East Atlantic horse mackerel (Trachurus trachurus and T. capensis)

open access: yesJournal of Fish Biology, 2020
Two sister species of horse mackerel (Trachurus trachurus and T. capensis) are described that are intensively harvested in East Atlantic waters. To address long‐standing uncertainties as to their respective geographical ranges, overlap and intraspecific ...

Results of the jack mackerel subpopulation discrimination feasibility study [PDF]

open access: yes, 1976
A report is made on the feasibility of discriminating subpopulations of jack mackerel, Trachurus symmetricus, off of the southern California and Baja California coast. Histochemical, morphometric, and meristic characters are compared from four samples of

Observation Bias in Metabarcoding

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT DNA metabarcoding is subject to observation bias associated with PCR and sequencing, which can result in observed read proportions differing from actual species proportions in the DNA extract. Here, we amplify and sequence a mock community of known composition containing marine fishes and cetaceans using four different primer sets and a ...

Lessons in cognition: A review of maze designs and procedures used to measure spatial learning in fish

open access: yesJournal of Fish Biology, Volume 107, Issue 4, Page 1093-1105, October 2025.
Abstract The use of different mazes to assess spatial learning has become more common in fish behavior studies in recent decades. This increase in fish cognition research has opened the door to numerous possibilities for exciting and diverse questions, such as identifying ecological drivers of spatial cognition and understanding the role individual ...
