Bivalve aquaculture has notably low environmental footprint compared to other animal production systems, with positive ecosystem effects including water filtration that benefit broader aquatic animal welfare.
Bivalve aquaculture environmental welfare analysis reveals positive spillover effects that benefit broader aquatic animal welfare. Improved water clarity from filter feeding enhances habitat quality for fish and other invertebrates that depend on visual orientation and healthy phytoplankton dynamics. Aquaculture structures function as artificial reefs providing shelter and habitat complexity. These ecosystem benefits are not incidental but represent a genuine contribution to broader aquatic welfare through improved environmental conditions. The low-input nature of bivalve production means its environmental welfare benefits come without the pollution and disease transmission concerns associated with fed aquaculture.
