Season- and depth-dependent variability of a demersal fish assemblage in a large fjord estuary (Puget Sound, Washington) [PDF]
, 2011 Fjord estuaries are common along the northeast Pacific coastline, but little information is available on fish assemblage structure and its spatiotemporal variability. Here, we examined changes in diversity metrics, species biomasses, and biomass spectra (

Fisheries Oceanography, EarlyView.ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Response of demersal fish communities to the presence of fish farms [PDF]
Marine Ecology Progress Series, 2005 The hypothesis that the presence of fish farms affects the communities of wild fish at large spatial scales was investigated through experimental trawl surveys. Three regions of the Aegean Sea with aquaculture zones were sampled in May and September (reproductive and recruit- ment periods, respectively for most species in the Aegean Sea).

Length-weight relationships of demersal fishes from the upper continental slope off Colombia [PDF]
, 2000 Parameters of the length–weight relationship of the form W=aLb are presented for 45 demersal fish species caught on the upper continental slope of the Caribbean Sea off Colombia. The b values varied between 2.13 and 4.97, with the mean b = 3.042 (95% CI,

A Comparison between Two Sonic Measuring Systems for Demersal Fish [PDF]
Journal of the Fisheries Research Board of Canada, 1970 Two sonic methods for estimation of abundance of fish stocks, the echo integrator and the digital counter methods, were compared on single and schooling fish in the Lofoten area of Norway during March 1969. Good correlation was obtained between the two systems for both situations, but the slopes of the regressions of integrated values on the digital ...
