Fisheries discard as an alternative for agricultural feed in the state of Campeche, Mexico

Resumen

Objective: To determine the incidence of non-target fishing species, in riparian
fishing, as a dietary alternative for the agricultural sector in the state of Campeche,
Mexico.
Design / methodology / approach: The ports surveyed in the state of Campeche:
Champotón, Seybaplaya and Campeche. A total of 89 questionnaires were applied
at random and at the free will to participate to coastal fishermen. The obtained data
were analyzed with the R vr 3.4.4 statistical software.
Results: The results showed that the coastal fishing catch is 760.1 kg on
average/week, and fishing discards of 30.42 kg/week. Of the bycatch, 68.8% is
discarded and the rest sold at a low price (US $ 0.2). Among the waste products,2
34 species stand out, but seven represent the 58.7% of maximum incidence,
mainly Bosh Ariopsis felis, Chac-chi Haemulon plumierii, Cojinuda Caranx crysos,
Ixpil Upeneus sp., Macabi Elops saurus, Postà Bairdiella chrysoura and Sardina
Herengula jaguana.
Delimitations / implications: There is a wide variety of species of which their
potential as a protein source is unknown, which can be used as input in feed.
Findings / conclusions: Registered fishing discards are made up of more than 30
non-target species and according to their incidence can be considered as inputs in
feed manufacturing for the agricultural sector.
