“…Both of these studies support Forsythe's hypothesis (1993) and show that squid hatching in warmer periods do 'out grow' their cooler-hatched counterparts. Forsythe et al (2001) furthermore unequivocally demonstrated this same temperature effect on growth using temperature-controlled grow-outs of known age squid hatched and grown in captivity. Grist & des Clers (1998) extended the Forsythe hypothesis and developed a model that explains how differing seasonal growth rates could affect the size distribution in populations of L. gahi.…”

“…Research continues to reveal that squid growth can be greatly modified by temperature or season of hatching (Rodhouse & Hatfield 1990b, Jackson & Choat 1992, Forsythe 1993, Brodziak & Macy 1996, Dawe & Beck 1997, Jackson et al 1997, Hatfield 2000, Forsythe et al 2001 as well as food supply (Jackson & Moltschaniwskyj 2001). However, our understanding of the causes of plasticity in squid growth is still far from complete.…”

Seasonal growth rates and size-and age-at-maturity were analysed for the small nearshore tropical loliginid squid Loliolus noctiluca off North Queensland, Australia, over a period of 2 yr. Age of individuals was determined using daily statolith increments. The life cycle of L. noctiluca off North Queensland was just over 4 mo. Analysis of growth found that growth was non-asymptotic, and the form of the curve; exponential, linear or log-linear, depended on sex and season that individuals were caught. Winter-caught individuals were the fastest growing and achieved the largest size compared with summer or autumn-caught individuals. Furthermore, females grew faster than males during the winter. The patterns of growth of L. noctiluca were compared between tropical North Queensland and temperate New South Wales. The temperate individuals lived longer and had slower growth rates. There was also a marked seasonal influence on the onset of sexual maturity among the North Queensland population, with the fastest growing winter-caught individuals maturing later than the autumn or summer individuals. L. noctiluca has a large latitudinal range from New Guinea to Tasmania, this study, and published work, suggests a trend towards increased lifespan and decreased growth rate with increasing latitude.

“…Some general trends were readily interpretable from known responses of squid to temperature (e.g. Forsythe et al 2001, Jackson & O'Dor 2001. This is demonstrated by the fact that all squid cohorts hatching out in warmer summer/autumn conditions (at each location) had higher growth rates than cooler winter/spring-hatched squid (Table 3).…”

Age, growth and maturity parameters were examined for the southern Australian ommastrephid squid Nototodarus gouldi. Squid were obtained from the fishing ports of: Ulladulla, New South Wales; Port Lincoln, South Australia; Lakes Entrance, Victoria; and Hobart, Tasmania. Squid were collected during 2 seasonal periods: summer/autumn-caught (warm-season squid) and spring-caught (cool-season squid) over 2 consecutive years (2000, 2001). N. gouldi is a sexually dimorphic species, with females generally reaching larger sizes than males. Initial genetic analysis has found only a single species in Australian waters. Statolith ageing revealed that squid completed their life cycle in <1 yr, and appear to hatch throughout the year. Trends in size, growth and maturity varied considerably between sites, seasons and years. Squids hatched in summer/autumn grew consistently faster than squid that hatched in winter/spring, presumably due to the influence of temperature on growth. Squid in 1999/2000 also grew faster than squid in 2000/2001. Growth of female squid in winter correlated with sea surface colour (SSC) during peak hatch periods, but the SSC relationship did not exist for males. Ulladulla squid were generally smaller, younger, had smaller gonads than most other squid and were possibly a smaller morph of the species. Tasmania and Lakes Entrance tended to have larger older individuals with larger gonads, while Port Lincoln was variable and intermediate. However, during spring 2001 both Tasmania and Port Lincoln had individuals that were much smaller than those of the other seasons for these sites, and were more like those from Ulladulla. Trends in age of mature individuals showed considerable variability (over 100 d from youngest to oldest) and there appeared to be a cline across all sites and seasons. Arrow squid appear to reveal marked plasticity in age, growth and maturity parameters, but currently the extent to which the environment or genetics control plasticity is unclear.

“…While many studies, both laboratory and field based, have provided examples of the dramatic effect of temperature on cephalopod growth (e.g. Forsythe et al, 2001;Hatfield, 2000;Segawa and Nomoto, 2002;Villanueva, 2000), including O. pallidus (Leporati et al, 2007), this effect has always been linked to the juvenile growth phase. It is likely that the second phase of growth is far less temperature dependent (Forsythe and Van Heukelem, 1987).…”

“…Cephalopod growth processes are responsive to a variety of abiotic factors, with temperature being the main factor influencing growth rate and growth variability if food is not limiting (Forsythe and Van Heukelem, 1987;Forsythe et al, 2001;Leporati et al, 2007;Villanueva, 2000). The juvenile growth phase is considered to be particularly sensitive to temperature (Semmens et al, 2004).…”

SUMMARYMany aspects of octopus growth dynamics are poorly understood, particularly in relation to sub-adult or adult growth, muscle fibre dynamics and repro-somatic investment. The growth of 5month old Octopus pallidus cultured in the laboratory was investigated under three temperature regimes over a 12week period: seasonally increasing temperatures (14-18°C); seasonally decreasing temperatures (18-14°C); and a constant temperature mid-way between seasonal peaks (16°C). Differences in somatic growth at the whole-animal level, muscle tissue structure and rate of gonad development were investigated. Continuous exponential growth was observed, both at a group and at an individual level, and there was no detectable effect of temperature on whole-animal growth rate. Juvenile growth rate (from 1 to 156days) was also monitored prior to the controlled experiment; exponential growth was observed, but at a significantly faster rate than in the older experimental animals, suggesting that O. pallidus exhibit a double-exponential two-phase growth pattern. There was considerable variability in size-at-age even between individuals growing under identical thermal regimes. Animals exposed to seasonally decreasing temperatures exhibited a higher rate of gonad development compared with animals exposed to increasing temperatures; however, this did not coincide with a detectable decline in somatic growth rate or mantle condition. The ongoing production of new mitochondria-poor and mitochondria-rich muscle fibres (hyperplasia) was observed, indicated by a decreased or stable mean muscle fibre diameter concurrent with an increase in whole-body size. Animals from both seasonal temperature regimes demonstrated higher rates of new mitochondria-rich fibre generation relative to those from the constant temperature regime, but this difference was not reflected in a difference in growth rate at the whole-body level. This is the first study to record ongoing hyperplasia in the muscle tissue of an octopus species, and provides further insight into the complex growth dynamics of octopus.
