Genotype and Environment (Water Temperature) Interactions on the Growth and Feed Efficiency of the Spotted Babylon Babylonia areolata

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Babylonia areolata is an emerging aquaculture species in China. Feed costs represent 40%–60% of its total production expenses, making feed efficiency a key target for genetic improvement. Water temperature is a major environmental factor in the cultivation of B. areolata, as it varies considerably across seasons, geographic regions and culture

Biosecurity Measures and Practices Relevant to Infectious Disease Management at Fish Farms in Northern Nigeria

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Aquaculture helps to bridge Nigeria's fish supply deficit and thus contributes to national food security. Southwest Nigeria dominates national aquaculture output, but fish farming in northern Nigeria is expanding. Understanding the infectious disease situation in this burgeoning segment of the sector, including how farmers act to prevent and ...

Market Systems Integration in Zambia's Aquaculture Sector: A Scoping Review of Value Chains, Supply Chains and Sustainability Challenges

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Aquaculture is increasingly important to food security, nutrition, livelihoods and economic development in Zambia, yet sectoral growth depends on more than production capacity. This scoping review synthesised evidence on Zambia's aquaculture market systems, focusing on value chains, supply chains and persistent evidence gaps.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, Volume 309, Issue 10, Page 2897-2912, October 2026.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 8, Page 887-893, October 2026.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...
