Abstract:
... Seahorses (family Syngnathidae) are ovoviviparous fish whose embryos can obtain paternal immunoprotection through the male's brood pouch, which is a specialized organ for pregnancy. Previous studies have revealed that seahorses have a unique immune system and alpha-2 macroglobulin (α2M) may be involved in male pregnancy. To ascertain the significance of α2M in the immune system of the brood pouch, ...

Abstract:
... Nile tilapia can achieve sexual maturity before reaching market size, which can be a great problem for production farms. To circumvent this problem the standard solution is to use androgen treatment to produce only male fish. However, the use of hormones has undesirable environmental issues due to residues in the water. One alternative would be by producing sterile triploid fish, which is conceptu ...

Abstract:
... Enriched rearing has been demonstrated to shape the phenotype of hatchery-reared salmonids and improve their post-release survival in the wild, thus having an important applied value in conservation. However, it is unclear if rearing conditions or survival selection during the early life stages induce long-term fitness effects on adult phenotypes. Using a paired full-sib set-up, we investigated th ...

Abstract:
... Nile tilapia is a GSD + TE (genotypic sex determination plus temperature effect) fish species. However, the role of 17β-estradiol (E2) during high-temperature-induced masculinization is unknown in fish species exhibiting GSD + TE. Because letrozole can specifically downregulate E2, the differences of the E2 level and sex ratio between the high-temperature-treated groups and various doses of letroz ...
