Neptunes Harvest

What Neptunes Harvest does

Neptune's Harvest is a Gloucester, Massachusetts-based manufacturer of organic fish-based fertilizers, operating as a division of Ocean Crest Seafoods Inc. (founded 1965). The fertilizer division, established in 1986, converts fish processing by-product — historically dumped back into the sea — into premium organic fertilizer using a proprietary cold hydrolysis process developed with the state of Massachusetts and local universities. This enzymatic process preserves heat-sensitive nutrients (vitamins, amino acids, enzymes, growth hormones) and avoids the synthetic inputs and odors associated with heat-processed fish emulsions. The product portfolio spans liquid and dry hydrolyzed fish fertilizers, seaweed and kelp products, crab and lobster shell products, specialty crop formulas (Tomato & Veg, Rose & Flowering, Lawn Starter, Turf Formula), BioNatural microbial soil amendments (Bioplin, NutriTech, NutriFoliar), insect repellents, and application equipment. The company's proprietary cold hydrolysis technology, exclusive supply agreements with Gloucester fishing vessels, OMRI-listed organic certification, and EPA registrations across multiple product lines form the technical and regulatory foundation of the business.

The company serves three core customer segments: home gardeners purchasing direct via e-commerce and phone orders, commercial farmers seeking organic yield improvement, and wholesale distributors and garden center retailers stocked through a nationwide distribution network with dedicated sales support and retail display rack programs. Pricing is transactional unit-based, with concentrated liquid fertilizers ranging from $30.75 per quart to $242 per five-gallon pail (each quart dilutes to 32 gallons), dry fertilizers from $32 to $149.99, and ancillary products spanning $2 merchandise to $253 specialty concentrates. Free continental US shipping and price matching are standard, with international shipping extending to 20+ countries across North America, Europe, Asia Pacific, and the Caribbean. Neptune's Harvest is family-owned across three generations (founder Anthony Parco Sr., five children, and five grandchildren active in the business), has never raised outside capital, and self-identifies as the leading US manufacturer of fish hydrolysate fertilizers. Distribution relies on a mix of D2C e-commerce (neptunesharvest.com), phone orders, wholesale distributors with retail display rack programs, and a retail store locator pointing consumers to local resellers.
