Active Versus Passive eDNA Sampling Across Depths at a Tropical Fish‐Aggregating Device (FAD)

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Sampling at a fish aggregating device over three consecutive days using active and passive samplers detected a total of 39 fish operational taxonomic units (OTUs). Of these, 25 OTUs were shared between the two sampling approaches. The composition of detected OTUs varied among days and between sampler types.

A new species of sardine, Sardinella pacifica from the Philippines (Teleostei, Clupeiformes, Clupeidae) [PDF]

open access: yesZooKeys, 2019
A new sardine, Sardinellapacificasp. n., is described on the basis of 21 specimens collected from the Philippines. The new species closely resembles Sardinellafimbriata (Valenciennes, 1847), both species having lateral scales with centrally discontinuous striae, a dark spot on the dorsal-fin origin, more than 70 lower gill rakers on the first gill arch,

Assessing the Progress of Stock Rebuilding in the Northeast Atlantic Against Levels That Can Produce Maximum Sustainable Yield

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 519-536, May 2026.
ABSTRACT Rebuilding fish stocks to levels above which they produce Maximum Sustainable Yield (MSY) is a management aim for all European commercially exploited stocks. Progress is typically monitored against the fishing mortality that produces MSY in the long term (FMSY), however, the corresponding biomass target (BMSY) is rarely evaluated nor reported.
