Abstract

There is fishing pressure on two species, Lutjanus peru and Lutjanus guttatus in the Gulf of Montijo, in Veraguas Pacific. Between November 2013 and September 2018, two species of commercial interest were registered weekly. The volume of Lutjanus peru and Lutjanus guttatus, sizes and weight were determined and analyzed, and the sizes were correlated with the weights, obtaining the determination coefficients (R2) and the correlation coefficients (r). In L. peru the sizes ranged between 12 and 84 cm with an average of 40.7 cm; the weight between 0.22 kg and 6.35 kg with an average of 1.33 kg; the total volume was 169,132 kg, R2 = 0.5705, r = 0.76. The size of L. guttatus was between 20 and 79 cm, with an average of 38.5 cm and the weight between 0.22 kg and 2.04 kg with the average 0.6 kg; the reported volume was 174,002 kg, R2= 0.5338, r = 0.73. L. peru represented 49.29% of the catches; on the other hand, L. guttatus corresponded to 50.71%. The length-weight relationship for both species was significant.
