We are usually interacting with anesthetized fish and farms are already doing manual tasks with this. We are also integrating camera's into existing workflow that do not handle the fish to improve a farms insight into their own farms.

There are many tasks within farms that are extremely manual that are a bottleneck, this is especially prevalent in offshore farms and marine species.

You should aim to improve or replace this parts, not mimic it.

Ask yourself: why are they sampling those fishes? Most probably just to take two measures: Weight and size. Age is known and fixed so if you know the three values, you can use conversion grow tables to know if the fish is growing well or not. Measure and weight an object without touching it directly is yet a solved problem. Clove oil lasts only for a while so being faster than a human should be also an objective. Reducing the human exposure to cold with automated work is also a desired goal.

But sampling all the fishes or 60% of them shouldn't be necessarily your main objective, because statistical benefits and cons are unbalanced with a biggest sample. You just would skyrocket the risk for having a few decimals extra of precision. Small sample here is a feature, not a bug.

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.
