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.

Dynamic Biofouling: DNA Analysis Reveals Patterns Across Ocean Conditions
Season explained the largest share of variation in biofouling communities, but substrate and depth still left their mark. That is the takeaway from a new study that deployed two synthetic materials at three depths across summer and winter, analyzing 432 samples with DNA metabarcoding. Winter assemblages, dense and persistent, were dominated by Hydrozoa; summer communities, rapid but removable, favored Oligohymenophorea and Malacostraca. This kind of empirical, replicated work sharpens our understanding of fouling pressure.
