Consumption to biomass (Q/B) ratio and estimates of Q/B-predictor parameters for Caribbean fishes [PDF]

, 2002
Estimates of the Q/B ratio and parameters of equations to 'predict' Q/B values for 116 fish stocks in the Gulf of Salamanca, Colombia are presented. A compilation of these estimates available for Caribbean Sea fishes (264 stocks) is also provided for ...

Monthly eDNA Metabarcoding Data From the Coastal North Sea Area Align With Fish Species‐Specific Life Cycle Events

Environmental DNA, Volume 7, Issue 4, July–August 2025.
In this study, we investigated the temporal and spatial patterns of fish communities within the 12 nautical miles limit of the Belgian part of the North Sea (BPNS) using eDNA 12S metabarcoding. Our findings revealed that while there are no temporal changes at the community level, species‐specific eDNA signals align with the species known biology in the

Field estimates of food consumption of the searobin Prionotus punectatus (Bloch, 1797) on the continental shelf off Ubatuba, southeastern Brazil

Brazilian Journal of Oceanography, 1998
Daily ration and population food consumption of juvenile and adult searobin Prionotus punctatus (54-314 mm total length) were estimated for the southeastern Brazilian shelf off Ubatuba (23°35'S, 45°00'W).

Spatial and Temporal Heterogeneity of Fish Spawning Dynamics on the West Florida Shelf During Fall

Fisheries Oceanography, Volume 34, Issue 4, July 2025.
ABSTRACT Identifying spawning areas for economically and ecologically important fishes is critical for fisheries conservation and ecosystem‐based management. We used genetic barcoding to identify fish eggs collected across the West Florida Shelf (WFS) during September of 2013, 2014, and 2019.

Genetic variability in Trigla lucerna by microsatellite molecular markers isolation

Italian Journal of Animal Science, 2010
Tub gurnard (Trigla lucerna L.) has been investigated as a new potential fish for farming in the last years. In fact, the decrease in prices, occurred after the increase of sea bass and sea bream production, is a source of many problems for several ...

Of Biogeography, Fishes and Kelp: Environmental DNA Metabarcoding the Great African Seaforest

Diversity and Distributions, Volume 31, Issue 6, June 2025.
ABSTRACT Aim The biodiversity associated with kelp forest ecosystems is understudied globally, including in South Africa, where kelp forests have expanded their range under climate change. This study used environmental DNA (eDNA) metabarcoding to assess fish biodiversity across an expansive range (~1000 km) of South Africa's kelp forests, contributing ...

Using High‐Resolution Fisheries Data to Identify Spatial Patterns in Retained Catch Compositions for Mixed Fisheries

Fish and Fisheries, Volume 26, Issue 2, Page 316-330, March 2025.
ABSTRACT Mixed fisheries exploit fish stocks that are heterogeneously distributed in space using gears that are not species selective. This poses a challenge for management as catch limits for less productive stocks constrain catches of more productive stocks leading to losses in yield and economic value. Decoupling catches of stocks caught together in

Design and Validation of an Open–Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep‐Sea Fish Assemblages

Ecology and Evolution, Volume 15, Issue 2, February 2025.
The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

Length-weight relationship of marine fish species off Sao Sebastiao system, Sao Paulo, Southeastern Brazil [PDF]

, 2000
The parameters a and b of the length-weight relationship of the form W = a . L super(b) were estimated for 57 fish species sampled in Sao Sebastiao Channel and shelf system in 1997, Sao Paulo, Brazil. The b values ranged from 2.746 to 3.617.
