You are right that for basic growth monitoring weight and size are the core measurements and statistical sampling is sufficient. We are actually testing underwater deployment for exactly that use case. Biomass estimation, feeding behavior tracking, population density. Non-contact measurement where the fish stay in the water.

But when you move into broodstock selection the requirements are completely different. It is not just weight and size anymore. Farms care about genotyping, body shape ratios, fin integrity, and overall quality markers that predict how well offspring will perform. You need detailed phenotypic data on individual fish and you want as many individuals as possible to improve selection accuracy. Marine species add another layer of complexity. Deformities are a major problem. Vertebral curvature, operculum malformations, color abnormalities. These are not things you can measure with a camera underwater. Farms are already taking fish out of the water for these inspections and doing it manually. We are not introducing handling where it did not exist. We are helping automate and track what they are already doing by hand.

The goal is to match the approach to the task. Underwater non-contact for biomass and behavior. Controlled environment with handling for broodstock phenotyping and deformity inspection. Different problems require different solutions.
