Fishman Chemical

Fishman Chemical is a small U.S.-based supplier of pharmaceuticals and chemicals used in aquaculture, ornamental fish, koi, and aquarium health. The business appears to operate primarily as a commercial distributor and seller of fish medications rather than as a human biopharma developer with a clinical pipeline. Publicly available materials associate the company with products such as chloroquine phosphate, metronidazole, nitrofurazone, oxolinic acid, tetracycline, sulfadiazine, and sulfamethazine for fish-health applications. Its commercial presence is linked to the fishchemical.com email domain and to the National Fish Pharmaceuticals website, which provides fish disease reference content and ordering contact details. The company has also been referenced in an FDA animal-veterinary warning letter concerning marketing of an unapproved chloroquine phosphate product for fish.
