Transcriptomic evidences of local thermal adaptation for the native fish Colossoma macropomum (Cuvier, 1818) [PDF]
Genetics and Molecular Biology, 2020 Brazil has five climatically distinct regions, with an annual average temperature difference up to 14 ºC between the northern and southern extremes. Environmental variation of this magnitude can lead to new genetic patterns among farmed fish populations.

Oocyte quality of tambaqui (Colossoma macropomum) during the reproductive season [PDF]
Brazilian Journal of Biology, 2015 The study aimed to analyze the Colossoma macropomum reproductive behavior and quality of the female gametes throughout the reproductive season. The experiment was carried out in Pimenta Bueno - Rondônia State (Northern Brazil) during the reproductive season (2010-2011) using 36 females. Each sampling was performed on a 15 ± 5 days interval.

Weaning of Colossoma macropomum larvae of different ages using different feeding strategies [PDF]
Ciência Rural: The present study evaluated the weaning of Colossoma macropomum. 6,720 larvae were distributed in 28 tanks (28 L) in a recirculating aquaculture system. Artemia nauplii were offered to the larvae in increasing quantities.

Medicinal and Aromatic Plant Oils in Aquafeeds: Mechanistic Perspectives on Growth Promotion, Immunomodulation, and Stress Resilience. [PDF]
Aquac NutrThe aquaculture industry is increasingly transitioning toward sustainable aquafeeds, driven by the economic and environmental necessity to replace marine‐derived fishmeal and fish oil with plant‐ and insect‐based alternatives. This nutritional shift introduces physiological challenges, accelerating the search for natural, sustainable functional ...

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends
Reviews in Aquaculture, Volume 18, Issue 4, September 2026.Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate
