Microalgae-Larvae Carbon Transfer: A Pathway to Sustainable Aquaculture.
A 33% carbon transfer efficiency from microalgae to shrimp larvae is a measurable, validated starting point. This study on *Litopenaeus vannamei* quantifies a biological pathway that has remained poorly understood. By calculating that global hatchery seed production retains approximately 9.2 tons of carbon annually, the research gives aquaculture a calibrated, empirical tool for carbon footprint assessments. Understanding drives protection. For deeper genomic context on algal symbiosis, see our related coverage of Symbiodiniaceae Minicircles.
CAP Protein Impacts Shrimp Growth, Metabolism, and Gut Microbiota.
A clear dose-response relationship is hard to find in aquaculture nutrition, but this study on *Litopenaeus vannamei* reveals one. When researchers fed the shrimp graded levels of Clostridium autoethanogenum protein as the primary protein source, growth performance followed a distinct biphasic curve. The CAP40 group achieved the highest specific growth rate, while inclusions above 44% significantly suppressed it. Broken-line regression pinpointed 39.44% as optimal. This precision matters.
Microbial Shifts Reveal Ecosystem Health in Shrimp Aquaculture Systems
Microbial communities do not merely reflect conditions in aquaculture; they carry a measurable signal of system health. This study tracked prokaryotic succession across three commercial *Litopenaeus vannamei* systems, pairing 16S rRNA sequencing with functional predictions to connect diversity shifts to cultivation design. The contrasts were sharp: earthen brackish ponds offered stability but hosted rising pathogenic genera, while concrete seawater systems showed higher metabolic potential yet greater turnover. That tension, between resilience and risk, is precisely the kind of empirical trade-off worth heeding.
Shrimp Immunity & Adaptation: Genomic Insights for Aquaculture Resilience
Penaeid shrimp farming is a high-stakes arena where disease and stress test every link in the chain. This study answers with hard data, mapping the hemocyanin gene family across four species to reveal how early duplication events shaped innate immunity. The finding that a truncated Heme oxygenase gene, under positive selection, maintains conserved expression in immune tissues is a concrete anchor. It grounds our understanding of resilience in measurable architecture, not guesswork. For practical breeders, this is the blueprint for targeted genetic improvement.
