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

Antibacterial Resistance in African Catfish Aquaculture: a Review

Notulae Scientia Biologicae, 2016
Antibacterial resistance (AR) is currently one of the greatest threats to mankind as it constitutes health crisis. Extensive use of antibacterial agents in human and veterinary medicine, and farm crops have resulted in emergence of antibacterial-resistant organisms in different environmental settings including aquaculture.

Commercially Exploited Seaweed Species in Africa: Occurrences, Chemical Composition, Current Value Chain and Opportunities for Value Addition

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Commercially exploited seaweed species in Africa, their biochemical composition, current uses, and value chain are reviewed. Potential value‐addition of seaweed is suggested regionally in Africa amongst countries producing similar seaweed species. ABSTRACT Africa has a wide range of coastal environments that support a diverse array of seaweed species ...

Nutritional Value of Biofloc Meal for White Cachama (Piaractus orinoquensis): Effects of Inclusion Level on Digestibility, Growth Performance, and Protein Retention

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Biofloc technology (BFT) offers a sustainable aquaculture strategy; however, the value of its byproduct, biofloc meal (BFM), as a feed ingredient requires validation for key species. This study evaluated the use of BFM from a tilapia–molasses system as a feed ingredient for white cachama (Piaractus orinoquensis) juveniles.

Long‐Term Effects of a Dietary Humic Substance–Butyrate Blend, and Yeast Cell Wall on Growth Performance, Immune Status and Gut Microbiota of Juvenile Channel Catfish Ictalurus punctatus

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This study evaluated the long‐term effects of a dietary humic substance and butyrate blend (HSB) alone or with yeast cell wall (Beta‐MOS) in channel catfish. Around 1440 fish (31.31 ± 0.24 g) were distributed among 12 outdoor tanks in a pond‐supplied flow‐through design. Four dietary treatments were evaluated in triplicate: Diets containing no

Effects of Commercial and Locally Formulated Diets on Growth Performance of Juvenile Oreochromis andersonii in a Hatchery System

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT In Namibia, the aquaculture sector faces significant challenges, mainly due to the high cost of imported commercial feed, which limits small‐scale farmers' productivity and food security. To address this, locally formulated feeds must be evaluated as sustainable alternatives.
