Short-beaked common dolphin

The Short-beaked common dolphin (Delphinus delphis) is a species of the Delphinidae family within the Cetacea order. In the context of specialized marine agriculture, these marine mammals are often identified as entities that affect the integrity of aquaculture infrastructure.

The cultures affected by their activity are primarily found in mariculture, such as shellfish farms and seaweed plantations. While dolphins do not consume these plants, their physical presence and interaction with submerged structures lead to significant damage to production facilities.

Their biology is defined by rapid movement and complex social foraging strategies. These mammals use high-frequency sonar to navigate, often leading them into conflict with man-made aquaculture grids and submerged equipment used for monitoring marine crops.

The damage caused is primarily mechanical and disruptive. Dolphins can damage nets, tear cables, and displace equipment, which disrupts the growth environment for marine organisms. This loss of infrastructure leads to crop vulnerability and significant financial risks for marine farmers.

Effective management requires non-lethal deterrents to protect aquaculture assets. Strategies include the deployment of high-frequency acoustic devices, installation of tensioned physical barriers, and spatial planning to avoid dolphin migratory paths, ensuring a balance between agriculture and marine biodiversity.
