Diel feeding of searobin Prionotus punctatus (Telestei: Triglidae) from coastal system off Ubatuba, Brazil

open access: yes, 1994
The feeding habits and the diel feeding periodicity of the searobin Prionotus punctatus were investigated at Ubatuba region (22º30'S) in the western South Atlantic. The samples were collected during consecutive 3 h periods over 24 h in January, 1987 and July and December, 1988. The diel feeding activity analysis indicated that Prionotus punctatus was a

Optimizing a metabarcoding marker portfolio for species detection from complex mixtures of globally diverse fishes

open access: yesEnvironmental DNA, Volume 5, Issue 6, Page 1589-1607, November 2023., 2023
We assessed the performance of 22 DNA metabarcoding primer sets for detecting 103 species of marine and freshwater bony fishes, elasmobranchs, cephalopods, and crustaceans. We find that a portfolio of four markers targeting 12S, 16S, and multiple regions of COI identifies all reference taxa to family and nearly 60% to species.

The comparative morphology of the musculature controlling the pectoral free rays in scorpaenoid fishes

open access: yesJournal of Morphology, Volume 284, Issue 7, July 2023., 2023
Free rays are a key adaptation in several benthic fish groups. Our comparative analysis of the pectoral free rays in three families of scorpaenoid fishes provides revised hypotheses regarding the identity and function of the specialized musculature and osteology associated with free rays. Abstract Free rays are ventral pectoral fin rays (lepidotrichia)

Forage Fish Species Prefer Habitat within Designated Offshore Wind Energy Areas in the U.S. Northeast Shelf Ecosystem

open access: yesMarine and Coastal Fisheries, Volume 15, Issue 2, April 2023., 2023
Abstract As the world develops sources of renewable energy, there is an intensifying interest in offshore wind energy production. The Northeast U.S. Continental Shelf (NES) ecosystem has favorable wind dynamics, with active development of wind energy.

Trends in Area of Occurrence and Biomass of Fish and Macroinvertebrates on the Northeast U.S. Shelf Ecosystem

open access: yesMarine and Coastal Fisheries, Volume 15, Issue 2, April 2023., 2023
Abstract Climate change can affect the habitat of marine species and hence their persistence and adaptation. Trends in area of occurrence and population biomass were examined for 177 fish and macroinvertebrates resident to the Northeast U.S. Continental Shelf ecosystem. Samples of these organisms were taken during a time series of research bottom trawl

Length‐Weight Relationships and Relative Condition Factor of 53 Species of Shallow‐Water Fish in the Colombian Caribbean Sea

open access: yesJournal of Applied Ichthyology, Volume 2023, Issue 1, 2023., 2023
Length‐weight relationships (LWR) were described for 53 species of shallow‐water fish caught with bottom trawls in a depth range between 7.3 and 108.1 m during September 2013 in the Colombian Caribbean Sea (fishing area 31 of the FAO). A linear regression was performed using the logarithmically transformed data to calculate a and b coefficients and ...

Ingestion of plastic debris by commercially important marine fish in southeast-south Brazil.

open access: yesEnvironmental Pollution, 2020
Rising concentrations of plastics in the oceans are leading to increasing negative interactions with marine biota, including ingestion by endangered and/or economically important seafood species such as fish.

The Protective Effect of Taurine on Oxidized Fish-Oil-Induced Liver Oxidative Stress and Intestinal Barrier-Function Impairment in Juvenile Ictalurus punctatus

open access: yesAntioxidants, 2021
Dietary lipids provide energy for growth and development and provide fatty acids necessary for normal structure and biological function. However, oxidized lipids cause oxidative stress and intestinal damage.
