ABSTRACT We developed and evaluated a fishery‐dependent catch‐per‐unit‐effort (CPUE)‐based proxy index for juvenile Japanese anchovy (Engraulis japonicus) recruitment‐related variability in the southeastern coastal waters of Korea. The proxy was constructed from bimonthly CPUE of the smallest juvenile size class (20–40 mm) in the anchovy drag‐net ...

Variants of GLM-standardised lobster CPUE for Tristan da Cunha for the 1997-2009 period [PDF]
Powerboat CPUE data for Tristan island are more limited (in terms of the associated data collected that might provide co-variates for a GLM-standardisation exercise) than the longline CPUE data for the outer three islands.

Abstract Estuary dependence to the survival of Chinook salmon was investigated at the Campbell River estuary, British Columbia, Canada. Replicate batches of marked smolts were transferred from a hatchery and released in 1983, 1984 and 1985 at four ecosystems, two that ensured estuarine experience (river, estuary) and two seawards of the estuary ...

ABSTRACT Assessing fish diversity and abundance is crucial for effective marine conservation and management strategies, particularly in ecologically sensitive areas such as the North Sea. Bottom trawling, one of the most commonly used fishing methods, is facing growing criticism, even for scientific purposes, and has already been banned in ecologically

GLMM- and GLM-standardised lobster CPUE from the Tristan da Cunha group of islands for the 1997-2007 period [PDF]
The longline CPUE series for the three outer islands are GLMM standardised. Year, month, area, trap-type, soak time, depth and year-area interactions are treated as fixed effects, and year-month interactions treated as a random effect.

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

GLMM- and GLM-standardised lobster CPUE from the Tristan da Cunha group of islands for the 1997-2010 period [PDF]
The longline CPUE series for the three outer islands are GLMM standardised through to 2010. Year, month, area, trap-type, soak time, depth and year-area interactions are treated as fixed effects, and year-month interactions treated as a random effect ...

Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions

Comparing eDNA metabarcoding and gillnet surveys in a Neotropical reservoir, this study finds that eDNA detects greater species richness yet reveals distinct assemblage structures. The results underscore the value of integrating both methods to achieve comprehensive biodiversity monitoring in hydropower‐impacted ecosystems.

Disentangling the Components Shaping Aquatic Richness Over Spatial Scales in Extreme Climatic Events
ABSTRACT Species richness in a region can be partitioned into three components: (1) spatial aggregation of individuals, (2) variation in total individual density and (3) species abundance distribution (SAD). However, it remains unclear how the influence of these components on richness changes under extreme climatic events.
