Protective Role of Egg Yolks From Different Avian Species on the Post‐Thaw Quality and Fertility of Cryopreserved Nile tilapia (Oreochromis niloticus) Sperm

Aquaculture Research, Volume 2026, Issue 1, 2026.
Egg yolks derived from various avian species have been widely applied as cryoprotective additives in mammalian sperm preservation; however, their efficacy in fish sperm cryopreservation remains poorly understood. Therefore, this study evaluated the cryoprotective effects of quail (Coturnix coturnix), chicken (Gallus gallus domesticus), and turkey ...

Anthropogenic Factors Drive the Depletion of Fish Functional Β Diversity Within and Outside Two National Reserves in the Peruvian Amazon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...

Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences.
