| In the Dermersal Fishing period of the Cruise T94/11/05 D-O (15/11/94-23/11/94) an area of 12,520.9 km2 was covered, that is. The Ecuadorean Shelf between the 02°10'0”S - 80°0'0”W and 14 to 115 meters deep throughout th Ecuadorean Continental Shelf of the Guayaquil Gulf area. A total of 78 species was identified as follows: 74 of this 95%, two of crustaceans, one of molluscan and one of holothurid (Sea cucumber). The estimated total biomass of demersal fish was of 78, 384.9 t, from which the 52% was concentrated between the 02°48'9”S and 03°15'8”S. The most abundant species were: Gallineta (Prionotus stephanophrys)(48,776.0 t), Corvina (Cynoscion spp.) (11,241.7 t), Barriga juma (Larimus spp) (4,111.8 t), Cabezudo (Caulolatilus spp) (2,554.2 t) and Torno... |

| Durante el 2009 (excepto mayo, agosto y septiembre), se analizaron un total de 3 772 especímenes de peces conformados por 16 especies, predominando la dica con 1561 individuos (42,3%), las menos capturadas fueron róbalo y chame con un individuo cada una (0,03%). La proporción de sexo macho hembra, talla promedio de captura y media de madurez sexual de las principales especies de peces fue: dama (1: 1,16; 23,7 y 20 cm LT), dica (1: 1,15; 17,3 y 16 cm LT), guanchiche (1: 1,2; 29 y 20 cm LT), ratón (1: 1,25; 23,5 y 19 cm LT) y bocachico (1:1,06; 21,6 y 20 cm LT). En los estadios de madurez sexual, la mayoría de las especies se encontraron en estadio I y II correspondientes a individuos hembras inmaduras; sin embargo, para el guanchiche predominaron las... |
