Molecular Characterisation and Reporter Gene Assay ofthe Three GnRH Isoforms and Two GnRH Receptors of a Clupeiform Fish, Japanese Sardine, Sardinops sagax melanostictus (Temminck & Schlegel, 1846)

open access: yesAsian Fisheries Science, 2022
The gonadotropin-releasing hormone (GnRH) is an important gene involved in fish reproduction and its action is mediated by GnRH receptor (GnRHR).

Distribution and abundance of ichthyoplankton in Florida Bay [PDF]

open access: yes, 2002
Ichthyoplankton was sampled at 14 stations with 60 cm bongo nets fitted with 0.333 mm mesh in basins throughout Florida Bay in 1994-1995. In addition, I compared collections made using an epibenthic sled to those made with standard ichthyoplankton bongo

A haplotype-resolved draft genome of the European sardine (Sardina pilchardus) [PDF]

open access: yes, 2019
The European sardine (Sardina pilchardus Walbaum, 1792) is culturally and economically important throughout its distribution. Monitoring studies of sardine populations report an alarming decrease in stocks due to overfishing and environmental change ...

Primer Length in Reverse Transcription Determines Biodiversity Recovery and Reproducibility in eRNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Primer length for reverse transcription significantly affects eRNA‐based biodiversity recovery and community structure. Shorter primers, particularly N4 and N5, in random priming and medium‐length primers, particularly T20, in oligo(dT) priming demonstrate superior performance, especially in detecting the rare biosphere.

Reproduction of Brevoortia aurea (Spix & Agassiz, 1829) (Actinopterygii: Clupeidae) in the Mar Chiquita Coastal Lagoon, Buenos Aires, Argentina

open access: yesNeotropical Ichthyology
Reproductive biology of the Brazilian menhaden, Brevoortia aurea (Clupeiformes), was studied in Mar Chiquita Coastal Lagoon. Its abundance was analysed in relation to environmental variables, and the main biological-reproductive parameters were estimated:

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

open access: yes, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

The oldest acanthomorph fossil (Actinopterygii, Teleostei) from the Early Cretaceous of Gondwana (Morro do Chaves Formation, Sergipe–Alagoas Basin, NE Brazil)

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract This paper presents the discovery of †Gondwanacanthus decollatus, a new genus and species of Early Cretaceous deep‐bodied fish from the late Barremian or early Aptian Morro do Chaves Formation in the Sergipe–Alagoas Basin, northeastern Brazil. It represents the first record of Acanthomorpha in Early Cretaceous Gondwana.
