Sperm Quality, Milt Biochemistry, and Cellular Ultrastructure in Fresh and Cryopreserved Sperm of Brycon amazonicus

Aquaculture Research, Volume 2025, Issue 1, 2025.
Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.

Long‐term effects of tagging fishes with electronic tracking devices

Fish and Fisheries, Volume 25, Issue 6, Page 1009-1025, November 2024.
Abstract Tagging fishes with internal or external electronic tracking devices (acoustic, radio, satellite, or archival tags) is invaluable to behavioural, ecological, and welfare research, but may have adverse effects on the animals studied. While short‐term responses to tagging (e.g., days to weeks) have often been investigated, less information is ...

slc26a12—A novel member of the slc26 family, is located in tandem with slc26a2 in coelacanths, amphibians, reptiles, and birds

Physiological Reports, Volume 12, Issue 11, June 2024.
Abstract Solute carrier family 26 (Slc26) is a family of anion exchangers with 11 members in mammals (named Slc26a1‐a11). Here, we identified a novel member of the slc26 family, slc26a12, located in tandem with slc26a2 in the genomes of several vertebrate lineages.

A newly developed cloning technique in sturgeons; an important step towards recovering endangered species

Scientific Reports, 2019
Several steps of sturgeon somatic cell nuclear transfer (SCNT) have been recently established, but improvements are needed to make it a feasible tool to preserve the natural populations of this group of endangered species.

Estimation of applicability of protein hydrolysate of black soldier fly (Hermetia illucens) larvae prepared using enzymatic hydrolysis as a fish feed component [PDF]

BIO Web of Conferences
The special advantage of black soldier fly (BSF) (Hermetia illucens) larvae for use as feed is their high protein content and low chitin content, which makes the larvae easier to digest, making them nutritious for fish, farm animals and birds.

Global introductions and environmental impacts of freshwater megafish

Global Change Biology, Volume 30, Issue 4, April 2024.
Of the 134 extant freshwater megafish species, 46% have been introduced outside of their native ranges. Over 50% of the alien megafish species with sufficient data to evaluate the severity of their environmental impacts have caused population declines or even extirpations of native species.

Environmental DNA reveals the ecology and seasonal migration of a rare sturgeon species in the Ural River

Environmental DNA, Volume 6, Issue 2, March–April 2024.
Environmental DNA technology has been used to identify rare sturgeons in the Ural River. The study found sturgeons at all sites in spring and autumn, confirming their semi‐anadromous ecology. This is the first documented eDNA detection of sturgeon specimens in the Ural River.
