Shellfish Farming
Description
The shellfish farming industry consists of businesses that cultivate aquatic animals for harvest, distinct from those that simply gather wild catch. These establishments actively manage controlled environments to nurture specific species such as oysters, clams, crabs, and shrimp under optimized conditions. Operations typically involve water quality management, habitat construction, daily feeding regimens, and disease monitoring to ensure healthy growth cycles. Growers meticulously track biological development stages to coordinate harvest timing with market demand, often utilizing specialized equipment for underwater feeding and extraction. The sector comprises a diverse mix of independent sole proprietors, small family-owned farms, and larger industrial aquaculture corporations. Scale varies significantly, ranging from small coastal plots producing hundreds of tons annually to massive integrated facilities operating across multiple jurisdictions. Many operations are located near nutrient-rich coastal waters where water currents facilitate natural filtration and temperature regulation. Some businesses integrate multiple species to reduce risk and maximize profitability, while others focus exclusively on high-value export markets. This sector plays a vital role in regional economies by providing local food sources and generating significant economic activity through tourism and supply chain logistics. The industry continues to evolve as technology advances, enabling more precise environmental controls and sustainable production methods that protect fragile marine ecosystems.
Hierarchy
| Code | Title | Description |
|---|---|---|
| 11 | Agriculture, Forestry, Fishing and Hunting 2-digit sector | The Sector as a Whole The Agriculture, Forestry, Fishing and Hunting sector comprises establishments primarily engaged in growing crops, raising animals, harvesting timber, and harvesting fish and other animals from a farm, ranch, or their natural habitats. The establishments in this sector are often described as farms, ranches, dairies, greenhouses, nurseries, orchards, or hatcheries. A farm may consist of a single tract of land or a number of separate tracts which may be held under different tenures. For example, one tract may be owned by the farm operator and another rented. It may be operated by the operator alone or with the assistance of members of the household or hired employees, or it may be operated by a partnership, corporation, or other type of organization. When a landowner has one or more tenants, renters, croppers, or managers, the land operated by each is considered a farm. The sector distinguishes two basic activities: agricultural production and agricultural support activities. Agricultural production includes establishments performing the complete farm or ranch operation, such as farm owner-operators and tenant farm operators. Agricultural support activities include establishments that perform one or more activities associated with farm operation, such as soil preparation, planting, harvesting, and management, on a contract or fee basis. Excluded from the Agriculture, Forestry, Fishing and Hunting sector are establishments primarily engaged in agricultural research (e.g., experimental farms) and government establishments primarily engaged in administering programs for regulating and conserving land, mineral, wildlife, and forest use. These establishments are classified in Industry 54171, Research and Development in the Physical, Engineering, and Life Sciences; and Industry 92412, Administration of Conservation Programs, respectively. |
| 112 | Animal Production and Aquaculture 3-digit subsector | Industries in the Animal Production and Aquaculture subsector raise or fatten animals for the sale of animals or animal products and/or raise aquatic plants and animals in controlled or selected aquatic environments for the sale of aquatic plants, animals, or their products. The subsector includes establishments, such as ranches, farms, and feedlots, primarily engaged in keeping, grazing, breeding, or feeding animals. These animals are kept for the products they produce or for eventual sale. The animals are generally raised in various environments, from total confinement or captivity to feeding on an open range pasture. The industries in this subsector are grouped by important factors, such as suitable grazing or pasture land, specialized buildings, type of equipment, and the amount and types of labor required. Establishments are classified in the Animal Production and Aquaculture subsector when animal production (i.e., value of animals for market) accounts for one-half or more of the establishment's total agricultural production. Establishments with one-half or more animal production with no one animal product or family of animal products of an industry accounting for one-half of the establishment's agricultural production are treated as combination animal farming classified in Industry 11299, All Other Animal Production. |

| 11251 | Aquaculture 5-digit NAICS industry | This industry comprises establishments primarily engaged in the farm raising and production of aquatic animals or plants in controlled or selected aquatic environments. These establishments use some form of intervention in the rearing process to enhance production, such as holding in captivity, regular stocking, feeding, and protecting from predators, pests, and disease. |
