Gonadal Development and Its Influencing Factors in the Red Swamp Crayfish (Procambarus clarkii): A Review

Biology
The red swamp crayfish (Procambarus clarkii) is a crucial freshwater aquaculture species in China, and the reproductive capacity and farming efficiency are critically dependent on gonadal development. Consequently, the acceleration and synchronization of

Gonadal Maturation and Spawning of Barred Loach (Nemacheilus fasciatus) Induced by Topical Gill Hormone Application

Jurnal Medik Veteriner
Barred loach Nemacheilus fasciatus are unable to reproduce naturally in captivity due to the lack of environmental cues and gonadal maturation occurs slower than in the wild.

Distinctive metabolite profiles in migrating Amur ide (Leuciscus waleckii) reveal changes in osmotic pressure, gonadal development, and energy allocation strategies

Frontiers in Environmental Science, 2022
Amur ide (Leuciscus waleckii) lives in alkali-saline water (pH = 9.6) in the Lake Dali and spawns in freshwater rivers after migration annually. During spawning migrations, Amur ide not only experience osmoregulation modification from alkali-saline water

Nesfatin-1-like peptide suppresses hypothalamo–pituitary–gonadal mRNAs, gonadal steroidogenesis, and oocyte maturation in fish†

Biology of Reproduction, 2020
AbstractNucleobindin (Nucb)-1 and Nucb2 are DNA and Ca2+ binding proteins with multiple functions in vertebrates. Prohormone convertase-mediated processing of Nucb2 results in the production of biologically active nesfatin-1. Nesfatin-1 is involved in the regulation of reproduction in many vertebrates, including fish.
