The early development of the Patagonian squid Loligo gahi D’Orbigny, 1835 in Peruvian Waters (Cephalopoda: Loliginidae)

The early development of the Patagonian squid Loligo gahi D’Orbigny, 1835 in Peruvian Waters (Cephalopoda: Loliginidae)

The early development of the Patagonian squid, Loligo gahi D’Orbigny,1835, was studied in the field and in the laboratory. Egg strands, spawned off San Lorenzo Island, Peru, were collected, carried to the laboratory, and incubated in a closed sea water system. Egg capsules ranged from 88 to169 mm in length, and each capsule contained between 56 and 114 fertilized eggs. Individual eggs ranged from 1,7 to 2,1 mm in length, and the mantle length of hatchlings varied from 1,9 to 2,8 mm. Development took about 20 days at a mean temperature of 19 ºC. The pattern of embryonic development is similar to that previously observed in other species of Loligo. Following hatching, paralarvaes survived for 45 days with a diet of zooplankton (copepods, mysids and polychaete larvaes).

El desarrollo temprano del calamar patagónico, Loligo gahi D’Orbigny, 1835 fue estudiado en el campo y en el laboratorio. Las puestas colectadas en la Isla San Lorenzo, Perú, fueron transferidas al laboratorio, e incubadas en un sistema cerrado de agua marina. Las cápsulas midieron de 88 a 169 mm de longitud y cada cápsula contenía entre 56 y 114 huevos fertilizados. Los huevos midieron de 1,7 a 2,1 mm de longitud y la longitud del manto de los individuos eclosionados varió de 1,9 a 2,8 mm. El desarrollo de las paralarvas se logró a los 20 días, a una temperatura promedio de 19 ºC. El patrón de desarrollo embrionario es similar al observado en otras especies de Loligo. Las paralarvas sobrevivieron 45 días con una dieta de zooplancton (copepódos, micidáceos y larvas de poliquetos).
