    Description: During a plankton survey along the edge of the continental shelf south of New Jersey in February 1969. Illex sp. larvae were caught in the vicinity of the Florida Current between Cape Hatteras and central Florida (28°30'N 80° 00'W). The larva from the latter area represents the most southwesterly capture that has been reported to date. Illex sp. larvae were also caught during surveys in February-March of 1981 and 1982 south of Newfoundland in the northern partof the Gulf Stream, the most easterly capture being at 40°09'N 53°00'W and northerly capture at 41°00'N 56°00'W. The larvae taken off Florida were 1.1-6.2 mm mantle length (ML) and those from the region south of Newfoundland were 2.4-6.6 mm. From the observed distribution and sizes of larvae in relation to water masses associated with the Gulf Stream System and in the light of recent observations on Illex illecebrosus spawning in captivity and temperatures required for embryonic development, it is considered that spawning probably occurs pelagically a in the winter months within the Gulf Stream or in the Gulf Stream-Slope Water frontal zone south of Cape Hatteras.

    An update of the fishery for short-finned squid (Illex illecebrosus) in the Newfoundland Area during 2000 with descriptions of some biological characteristics (2001)

    Description: Subarea 3 landings totalled only 310 t in 2000, representing a slight increase from 19 t in 1999 and representing the third consecutive year of very low abundance, with landings of less than 1000 t. Landings in 2000 were exclusively from the inshore Newfoundland jig fishery in Div. 3KL and primarily during September-October. Samples acquired from the commercial fishery at two inshore localities indicated that mean mantle lengths for both sexes were much smaller than in 1998 and were generally comparable with the smallest observed since 1976, for comparable time periods. Coincident with such small size, male sexual maturation was less advanced than in previous years. Small mean length at Newfoudland in 2000 was consistent with small mean weights observed in 2000 from surveys during July on the Scotian Shelf and during autumn on the northeast USA Shelf. Such small size is believed to reflect a low proportion of squid from late spawning.

    Population structure, growth, and sexual maturation of short-finned squid (Illex illecebrosus) at Newfoundland (1997)

    Description: We describe size at age, growth, and population structure of short-finned squid (Illex illecebrosus) from Newfoundland waters during 1990. Ages were estimated from statolith increment counts and used to back-calculate hatching dates. Hatching ranged between December and June with the hatching months of March to May predominating. Constant interchange of individuals in the inshore population was evident in that the modal month of hatching progressed from March within the earliest (July) sample to May within the latest (November) sample. Within the mantle length range available, growth was adequately expressed by a linear model. Females grew faster than males, and during the March to May months of hatching, length at age and growth rate increased with hatching month. This positive effect of late time of hatching was also seen in growth in mass and in gonad development and sexual maturation.
