Effect of salinity on the oxygen consumption of larvae of the silversides Odontesthes hatcheri and O. bonariensis (Osteichthyes, Atherinopsidae) [PDF]

Brazilian Archives of Biology and Technology, 2008
Starved larvae of the silversides O. hatcheri (2- and 5-days-old) and Odontesthes bonariensis (5-days-old) were used to compare the oxygen consumption rates at 0, 5, 10, 20 and 30 ppt salinity. Oxygen consumption of O. hatcheri and O.

Coexistence of genotypic and temperature-dependent sex determination in pejerrey Odontesthes bonariensis. [PDF]

PLoS ONE, 2014
In this study, we examined whether a homolog of the master sex-determining gene amhy of Odontesthes hatcheri is present and plays any role in testis determination of pejerrey O.

Sex Determination in Sponges. [PDF]

Mol Reprod Dev
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change. [PDF]

J Fish Dis
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Identification of a candidate sex determination gene in Culaea inconstans suggests convergent recruitment of an Amh duplicate in two lineages of stickleback. [PDF]

J Evol Biol, 2022
Sex chromosomes vary greatly in their age and levels of differentiation across the tree of life, largely due to the rates of sex chromosome turnover in different lineages. Here, we identify a novel, and likely young, turnover in stickleback fishes. Using whole‐genome sequencing we identify AmhY, a male specific duplication of the autosomal gene Amh, as

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

Reviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from
