Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

open access: yes, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

open access: yesFisheries Oceanography, Volume 35, Issue 3, Page 397-412, May 2026.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Status of the spawning biomass of the Pacific sardine, 1978-79 [PDF]

open access: yes, 1979
State law requires that the population of Pacific sardines, Sardinops sagax caeruleus, must reach a minimum spawning biomass of 20,O0O short tons before initiation of a fishery.

Anchovies Engraulidae Ice Cream

open access: yesInternational Journal For Multidisciplinary Research
Anchovies have many vitamins and minerals that provide significant health benefits. They are best known as a source of omega-3 fatty acids, which promote brain and heart health. On the other hand, ice cream is a highly popular, palatable, nutritious, and commercially important dairy product, usually made from dairy products, such as milk and cream, and

Juvenile European anchovy otolith microstructure

open access: yesScientia Marina, 2006
Juvenile European anchovy (Engraulis encrasicolus) has a complex incremental growth pattern that was studied using scanning electron microscope (SEM) and optical microscope observations. Daily increments were identified and related to rhythmic growth patterns while double-band structures were identified as one increment.

Otolith elemental composition reveals separate spawning areas of anchoveta, Engraulis ringens, off central Chile and northern Patagonia

open access: yesScientia Marina, 2019
The anchoveta (Engraulis ringens) is widely distributed throughout the Humboldt Current (4°30′-44°S). In recent years, its eggs and larvae have also been found inside fjords and channels of northern Patagonia, close to the southern limit of the central ...

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]

open access: yes, 1987
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Modeling Environmental DNA Transport in the Coastal Ocean Using Lagrangian Particle Tracking

open access: yesFrontiers in Marine Science, 2019
A number of studies have illustrated the utility of environmental DNA (eDNA) for detecting marine vertebrates. However, little is known about the fate and transport of eDNA in the ocean, thus limiting the ability to interpret eDNA measurements.
