While the proximity of Haiti to the Windward Passage and the north-flowing currents off the Venezuelan coast place it in the path of major fish migrations, including tuna, marlin, bonito, and sardines, the commercial fishing industry is not developed. Reef fish, including giant grouper and rock lobster, are important food sources because deep-sea fishing is limited. Fisheries have been successfully developed in the small ponds and in the irrigation and drainage ditches of the Artibonite Plain. Carp and tertar, a native fish, are abundant, but lack of transport and other facilities limits this important food source to local consumption. The catch was estimated at 5,000 tons in 2000, including 200 tons of Caribbean spiny lobster and 380 tons of conch.
