Fish die. Whether it is through disease or adverse weather, or even bad luck.
Either way, it is very important to have the right tools/technology to dispose of the unusable stock appropriately. In the best circumstances this waste can then be used or recycled to become aquaculture feed and sold on.
Zero waste – aquaculture animal by-products
The Scottish Government website talks about the disposal of dead fish and aquatic animal by-products (ABPs), describing them as covered by the Animal By-products (Enforcement) (Scotland) Regulations 2013. “Any business generating material of aquatic origin which is not intended for human consumption needs to be aware of how these regulations apply to their business” they explain.
They reference three categories of aquatic ABP; Category 1 (few aquatic animals would fall into this category) “Aquatic animals containing certain prohibited substances above specified levels or unacceptable levels of environmental contaminants (for example fish contaminated with fuel from an oil spill or fed contaminated feed)”.
Category 2 (mortalities would fall into this category) “Fish or aquatic animals which die from a notifiable disease - such as infectious salmon anaemia (ISA), Aquatic animal products containing unacceptable levels of residues of veterinary drugs and higher than specified minimum levels of certain contaminants, fish or parts of fish that die, other than being slaughtered for human consumption, including fish killed for disease control purposes. This includes all mortalities occurring during the production cycle in aquaculture, including fish that die from disease, third country imports that fail to comply with veterinary requirements for their importation into the community” and
Category 3 (processing waste would fall into this category) “Carcases (heads, frames) and parts of slaughtered fish, which are fit for human consumption but are not intended for human consumption for commercial reasons, carcases and parts of slaughtered fish, which are unfit for human consumption, but derive from carcasses that are fit for human consumption i.e. viscera; internal organs containing parasites, carcases and parts of carcases of slaughtered fish, which are rejected as unfit for human consumption, but which do not show signs of disease communicable to humans or animals, fish or other sea animals, except sea mammals, caught in open sea for the purposes of fishmeal production or bait, by-products from fish plants manufacturing fish products for human consumption and shells from shellfish that contain soft tissue or flesh.”
