In the past 14 years, landings of the small pelagic fishes in Magdalena Bay had an average of 52,024 t per year, with an average catch of 42,826 t of Pacific sardine and 755 fishing trips. During 2013, 796 fishing trips were realized and landings of small pelagic fishes were 54,666 t of which 29,274 t were Pacific sardine. Regard the specific composition of small pelagics landed in Magdalena Bay in 2013, Sardinops sagax accounted for 53.6%, Opisthonema 18.9%, E. teres 5.0%, S. japonicus 4.4%, C. mysticetus 7.9% and 10.3% was a mixture of some of these species. 15 vessels landed small pelagics during 2013, but only 9 of them realized the 90% of the total fishing trips. In relation to the size composition of Pacific sardine, 97.3% of catches were above of the minimum legal size (150 mm SL). Most of these sardines (87.7%) had sizes between 170-215 mm SL. The age composition determined for 2013 reflects the above. Age group 1 was the most abundant, but goups 2, 3 and 4 were also significant amounts on landings. In all months of 2013 mature or spawning sardines were presented, but higher reproductive activity was during February and April. Currently Pacific sardine shows a more continuous reproductive activity. During January to July 2014, have been downloaded 44,414 t of small pelagic fishes, of which 37,389 t was Pacific sardine. The importance of the remaining small pelagics was: Opisthonema spp 9.1%, E. teres 4.8%, S. japonicus 1.4%, C. mysticetus 0.3% and 3.0% was a mixture of species.
