Description
Jeremie Bauer, Jorge Olmos, and Enric Gisbert present a 2025 review of feeding farmed sea urchins to fatten and colour their roe, the part people eat. Wild urchins from bare rock zones are thin; short feeding can make them marketable while clearing barrens that smother kelp. The review weighs feeds across many studies.
Seaweed feeds grow and colour roe best, but cost and supply bite. Soy protein is cheaper, yet anti nutrient factors cap how much can be used. Fat share in the feed proves critical. The authors map gaps: big scale economics, new additives, and mixed species farming that pairs urchins with their own waste eaters.
