Essential and Non-Essential Elemental Composition and Health Risks in Pacific Sardine in the Northwest Pacific Ocean

Journal of Marine Science and Engineering
Pacific sardine (Sardinops sagax) in the northwest Pacific Ocean (NPO) not only preserve the equilibrium of the NPO food chain, but also serve as a source of nutrition for humans. In order to evaluate the levels of various elements in S.

Bayes theorem applied to the yield estimate of the Pacific sardine (Sardinops sagax coeruleus Girard) from Bahia Magdalena, Baja California Sur, Mexico

Ciencias Marinas, 2002
 The yield of the Pacific sardine Sardinops sagax caeruleus from Bahía Magdalena, B.C.S., was analyzed using a stockrecruitment model. The model was stochastic, and it used the hypotheses of process error (H1) in the model, and observation error (H2) in

Validation of periodicity of growth band formation in Pacific Sardine (Sardinops sagax) from a captive growth experiment

Marine Biology
Pacific Sardine (Sardinops sagax) in the Northeast Pacific Ocean are aged for stock assessments assuming the formation of two otolith growth bands (one opaque and one translucent) a year, but the periodicity of band formation has not been fully validated.

Tuning the tools: Validating empirical and modelled correction factors for diet estimation in pelagic teleosts

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2218-2233, July 2026.
Abstract As quantitative diet estimates from biochemical markers grow in popularity, the necessity for robust species‐ and tissue‐specific correction factors, including trophic discrimination factors (TDFs) for stable isotopes and calibration coefficients (CCs) for fatty acids, becomes increasingly urgent.

Characterization of Incremental Markings in the Sagittal Otolith of the Pacific Sardine (Sardinops sagax) Using Different Imaging Modalities

Minerals
Teleost fish possess calcium carbonate otoliths located in separate chambers (utriculus, sacculus, and lagena) of their membranous labyrinth. This study analyzed the surface topography of the sagittal otolith of the Pacific sardine (Sardinops sagax) and ...

Advancing Ecological Understanding and Sustainable Management of Small Pelagic Fish

Fish and Fisheries, Volume 27, Issue 4, Page 850-864, July 2026.
ABSTRACT Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing ...

Temporal and spatial variability in 'Tetracotyle' type and metacercariae infection in the South African sardine, Sardinops sagax [PDF]

, 2013
Spatial and temporal variation of "tetracotyle" type metacercariae infection in the eyes of the South African sardine, Sardinops sagax, was examined to elucidate the potential use of this parasite as a biological tag, and to test the hypothesis that the ...

Using the Diet Composition of Adult Chinook Salmon to Understand the Regional Structure of Salish Sea Forage Communities

Fisheries Oceanography, Volume 35, Issue 4, Page 565-579, July 2026.
ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...
