    Respiration and Swimming Performance of Short-finned Squid (Illex illecebrosus) (1985)
    NAFO
    In:  nafo, 9 . pp. 133-138.
    Details
    Publication Date: 2020-06-18
    Description: Intramantle pressure transducers allowed the monitoring of respiration and swimming performance of cannulated and freeswimming squid (IIlex illecebrosus). Jet pressure and oxygen consumption of individual squid were measured simultaneously in a tunnel respirometer at various swimming speeds. The rate of oxygen consumption increased logarithmically with swimming speed up to critical speeds of 70-90 cm/sec (about two body lengths per second). Oxygen consumption values for a400 g squid at 15° C were the highest that have been recorded for marine poikilotherms at this size and temperature: 313 ml/kg/hr for standard metabolism and 1,047 ml/kg/hr for active metabolism at maximum speed. A 40-cm squid (total length) uses about six times more energy per unit distance than a sockeye salmon of similar length at 15° C. The rate of oxygen consumption increased linearly with average jet pressure generated in the mantle cavity and the relationship was highly correlated for speeds of 0.15 0.80cm/sec. The results from telemetric monitoring of jet pressure generated by a free-swimming squid in a 15-m pool and the oxygen-pressure relationship show great promise for studying the activity and bioenergetics of squid in nature.

    Predation by Atlantic Cod (Gadus morhua) on Short-finned Squid (Illex illecebrosus) off eastern Newfoundland and in the northeastern Gulf of St. Lawrence (1984)
    NAFO
    In:  Serial / Northwest Atlantic Fisheries Organization : N, 905 . pp. 1-16.
    Details
    Publication Date: 2020-06-19
    Description: In years of high abundance, the short-finned squid (Illex illecebrosus) was a common prey of Atlantic cod (Gadus morhua) in summer and autumn in both inshore and offshore waters of eastern Newfoundland and in the eastern and northern Gulf of St. Lawrence.The frequency of occurrence of squid in cod stomachs and the number of squid per stomach increased with cod length. The intensity of predation by cod on squid was low compared with peak predation on capelin (Mallotus villosus) and sand lance (Ammodytes sp.). Nevertheless, the annual immigration of squid in years of high abundance provided an increase in total food availability, especially for large cod.

    Evaluation of Male Reproductive Features as Maturity Indices for Short-finned Squid (IIlex illecebrosus) (1985)
    NAFO
    In:  NAFO Scientific Council Studies, 9 . pp. 107-115.
    Details
    Publication Date: 2020-06-19
    Description: Various aspects of maturation in male IIlex illecebrosus were examined in an attempt to find evidence for a more realistic maturity scale than that currently in use. Simple indices, based on morphology of the hectocotylized arm, failed to provide satisfactory relationships, but the observed variation in hectocotylus measurements may provide useful insights into the population ecology of the species. The earlier maturation of males than females and the observed premature release of spermatophores cast doubt on the usefulness of spermatophore counts as the basis for developing a reliable maturity scale for male I. illecebrosus. Preliminary examination of spermatophores and spermatozoa with lighl and scanning electron microscopes have so far failed to reveal any difference between material from early and late "mature" males.

    Yield Analysis for the Long-finned Squid, Loli•o pealei (LeSueur) (1984)
    NAFO
    In:  Serial / Northwest Atlantic Fisheries Organization : N, 894 . pp. 1-29.
    Details
    Publication Date: 2020-06-19
    Description: A modified version of yield-per-recruit analysis wasused to estimate potential yields in the Loligo pealei fishery off the northe stern USA. The mode1 accepts monthly values of growth and fishing, spawning and natural mortality rates and assumes two cohorts per year class, as associated with pawning peaks. Two patterns of exploitation were examined by simulatting dominance of the international fishery (offshore, winter fishing coupled with the domestic inshore summer fishing) and the domestic fishery alone through varistion of the monthly pattern of fishing mortalita. Parameter estimates were derived from survey catch per tow and commercial catch data.

    Embryonic development of the squid, Illex illecebrosus, and effect of temperature on development rates (1982)
    NAFO
    In:  Journal of Northwest Atlantic Fishery Science, 3 . pp. 41-45.
    Details
    Publication Date: 2020-06-18
    Description: Development stages for artificially fertilized and naturally spawned eggs of Illex illecebrosus were observed and a staging scheme proposed which relates to earlier studies on naturally spawned eggs of Illex coindetii and artificially fertilized eggs of Todarodes pacificus. Photographs and descriptions of stages provide a reference for embryonic development of small ommastrephid eggs and an aid to the identification of egg masses of the species in nature, an essential step in understanding its life cycle. Embryonic development in Illex illecebrosus fails at temperatures below 12.5°C. and the development rate at 21°C is nearly twice that at 12.5°C. This temperature requirement restricts the spatial and temporal distribution of spawning in this squid, and temperature-related development rates allow prediction of the age of egg masses found in nature in water masses of a particular temperature.
