Fish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

COMPARATIVE GEOGRAPHIC VARIATION IN MENIDIA [PDF]
Evolution, 1974 Increasing evidence indicates an important influence of the physical environment on allozyme variation (Johnson et al., 1969; Koehn, 1969; Johnson, 1971; Koehn and Mitton, 1972; Kojima et al., 1972; Merritt, 1972; Koehn et al., 1973). One possible test of the importance of the external environment is a comparison of patterns of geographic variation in ...

Comparing Aquatic Environmental DNA Collection Methods Across a Diel Cycle in a Lotic System
Environmental DNA, Volume 8, Issue 2, March/April 2026.Water samples were collected over 25 h from the Tangipahoa River, Louisiana, using active and passive environmental DNA methods to detect fish assemblages. Active sampling involved collecting water samples at hourly intervals for 25 h, whereas passive sampling deployed a stationary filter for 25 h.
