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

open access: yes, 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.

Observations on some Tasmanian fishes: Part XXXI- Review of Gnathanacanthidae [PDF]

open access: yes, 1986
GNATHANACANTHIDAE. The sole representative of this family, Gnathanacanthus goetzeei Bleeker, 1855, specified in the last century as the type of three different genera by Dutch, English and Australian ichthyologists, with type locality Tasmania (twice ...

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

open access: yesEcology 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 ...

Fish assemblages found in tidal-creek and seagrass habitats in the Suwannee River estuary [PDF]

open access: yes, 2006
Fish assemblages were investigated in tidal-creek and seagrass habitats in the Suwannee River estuary, Florida. A total of 91,571 fish representing 43 families were collected in monthly seine samples from January 1997 to December 1999.

Bottom Trawling and Multi‐Marker eDNA Metabarcoding Surveys Reveal Highly Diverse Vertebrate and Crustacean Communities: A Case Study in an Urbanized Subtropical Estuary

open access: yesEnvironmental DNA, Volume 6, Issue 6, November–December 2024.
We demonstrated the effectiveness of eDNA metabarcoding as a valuable addition to bottom trawling for monitoring the species composition and spatial distribution of fish and crustacean communities in urban estuaries. We also showed that a multiplexed‐marker approach enhances species detection, especially in some taxa, for example, cartilaginous fish ...

Larval and settlement periods of the northern searobin (Prionotus carolinus) and the striped searobin (P. evolans) [PDF]

open access: yes, 2002
This study reports new information about searobin (Prionotus spp.) early life history from samples collected with a Tucker trawl (for planktonic stages) and a beam trawl (for newly settled fish) from the coastal waters of New Jersey.

Hyperostosis in Fishes: An Update With New Species Records

open access: yesJournal of Morphology, Volume 285, Issue 11, November 2024.
Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

Re‐evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2

open access: yesEFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.

Using otolith shape for intraspecific discrimination: the case of gurnards (Scorpaeniformes, Triglidae)

open access: yesFrontiers in Marine Science, 2015
The sagittal otoliths are sound transducers and play an important role in fish hearing. Triglidae (Teleostei, Scorpaeniformes) are known for sound producing ability in agonistic contexts related to territorial defence, reproduction and competitive feeding (Amorim et al., 2004). Chelidonichthys cuculus and C.

Environmental DNA for monitoring the impact of offshore wind farms on fish and invertebrate community structures

open access: yesEnvironmental DNA, Volume 6, Issue 4, July–August 2024.
Offshore windfarms are marine areas that are difficult to access, and innovative monitoring techniques are needed to study their impact on marine biodiversity. Water sampling and trawl catches conducted in parallel in 30 sites in the Belgian part of the North Sea showed that 12S eDNA metabarcoding retrieved 85.7% of the fish species caught in the beam ...
