Paramount Fish Co in downtown San Diego operates a small-scale commercial fishing business from the North Harbor Drive waterfront, selling sushi-grade catch directly to the public from the same dock where the company's vessel FV Rebecca Jean unloads. The operation specializes in locally caught bluefin tuna, yellowtail, yellowfin, dorado, white seabass, halibut, and skipjack — seasonal species that also supply the Saturday stalls at Tuna Harbor Dockside Market on Harbor Lane. As a member of the Community Supported Fisheries network, Paramount commits to hook-and-line and other low-bycatch methods that minimize seafloor contact and reduce environmental impact. The market accepts cryptocurrency alongside standard credit and debit payments, a retail flexibility uncommon among San Diego's dockside fish vendors. Local restaurants and home cooks who source whole fish from Paramount's counter feed the same waterfront culinary ecosystem anchored by Harbor Breakfast on India Street. Whole bluefin-tuna breakdowns — loins, collars, belly cuts, and saku blocks graded for raw consumption — represent the most complex processing the operation handles at its Harbor Drive facility.
