Pinfish

Lagodon is a monospecific genus of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. The only species in the genus is Lagodon rhomboides, the pinfish, red porgy, bream, pin perch, sand perch, butterfish or sailor's choice. This fish is found in the Western Atlantic Ocean and Gulf of Mexico.

Distribution

Lagodon is found in Bermuda and along the United States coast from Massachusetts to Texas, and down along the Mexican Gulf Coast. It is also found along the northern Yucatán coast and near some northern Caribbean islands, but it is less common in the tropical portions of its range. The adult pinfish prefers waters between 30 and 50 feet deep, while the juvenile is more common where there is some cover, such as seagrass beds, rocky bottoms, jetties, pilings, and mangroves. It prefers higher-salinity water. It rarely schools, but it associates with other individuals, especially where food items such as barnacles are abundant.

Behaviour

Lagodon undergoes ontogenetic changes in the morphology of their dentition and gut tracts which affect diet throughout their life history. Juvenile pinfish are carnivorous and primarily eat shrimp, fish eggs, insect larvae, polychaete worms, and amphipods. As pinfish become older and larger they become increasingly more herbivorous, with plant matter comprising >90% of the diet for pinfish greater than 100mm.
