“…Four species of Loligo were evaluated for their potential to be cultured in captivity for use in biomedical research. Work began with L. opalescens (Yang et al 1983a(Yang et al , 1983b, then Loligo vulgaris (Turk et al 1986), L. pealeii (Hanlon et al 1987) and finally Loligo forbesi (Forsythe and Hanlon 1989;Hanlon et al 1989). Even though these studies were not motivated by fisheries/life-history investigations, the results were invaluable.…”

The impact of temperature on cephalopod growth has become a productive area of study. Current knowledge of squid growth owes much to earlier laboratory studies on octopuses and cuttlefishes that revealed rapid temperature-sensitive growth. Advances in laboratory culture of squids eventually revealed the dramatic extent to which rising water temperature accelerates growth rates. This led to proposal and testing of a working hypothesis, the Forsythe Hypothesis, that during periods of gradually warming temperature, monthly cohorts of squids experience warmer conditions and grow faster, and perhaps larger, than older, earlier-hatched cohorts. The advent of statolith increment analysis for determining age in field-caught squids has provided a powerful tool in ground-truthing this hypothesis in nature. This hypothesis, now termed here the Forsythe Effect, has been laboratoryand field-tested over the past 10 years and been strongly supported. Food availability and inherent species-specific physiological limits must also be accounted for in predicting growth. Gaps still exist in our precise understanding of the temperature-induced changes in form and duration of squid growth. Acute and chronic ocean-scale seawatertemperature change events will compel us to look to squids as 'bioindicators' of environmental condition and to statoliths as the 'archives' of this information.

“…Paralarvae typically hatch at night and perform a diel migration to the upper 15 m at night and down to approximately 50 m during the day (Zeidberg and Hamner, 2002). Newly-hatched paralarvae are susceptible to oceanographic conditions as they are unable to hold their position against a weak current until the late paralarval stage [>30 days old (Yang et al, 1983(Yang et al, , 1986].…”

The influence of the El Niño Southern Oscillation on paralarval market squid (Doryteuthis opalescens)

California market squid (Doryteuthis opalescens) support one of the largest and most valuable fisheries in California. However, market squid abundance varies greatly from year to year, ostensibly as a result of the El Niño Southern Oscillation (ENSO) phenomenon, although the underlying mechanism is not known. Classic hypotheses suggest that the early larval stage may be the key to uncovering this mechanism. Here, we perform a time series analysis, length‐distribution analysis, and growth analysis to investigate the effects of ENSO on paralarval D. opalescens. In contrast to classic hypotheses, we find that ENSO does not drive early paralarval survival or growth. Instead, we find that the ENSO operates primarily on the late paralarval stage, with El Niño conditions associated with lower survival of late‐stage paralarvae. We also find that time series models which use ENSO conditions during the previous juvenile and adult stage outperform models that use ENSO conditions during the paralarval stage. Our results suggest that the population bottleneck for D. opalescens does not occur in the early paralarval stage, but instead lies later in the squid's life.

“…The challenges have been the very small hatching size of most species, recruitments for live zooplankton as food, constant swimming and susceptibility to skin damage resulting from impact with tank walls (Hanlon 1990; Hanlon, Turk & Lee 1991). Between 1979 and 1983, the Marine Biomedical Institute successfully reared Loligo opalescens (Hanlon, Hixon, Hulet & Yang 1979; Yang, Hanlon, Krejci, Hixon & Hulet 1980; Yang, Hanlon, Krejci, Hixon & Hulet 1983a), L. forbesi (Hanlon, Yang, Turk, Lee & Hixon 1989) and L. vulgaris (Turk, Hanlon, Bradford & Yang 1986) from hatching to adult size in the search for an ideal squid species culture for biomedical and aquaculture studies. Yang, Hixon, Turk, Krejci, Hanlon and Hulet (1983b) successesfully cultured L. opalescens from field‐collected eggs to the first laboratory‐spawned generation.…”

Loligo vulgaris is a commercially important squid throughout the Mediterranean region and is a candidate species in biomedical and aquaculture research. Some loligo species (L. opalescens, L. forbesi, Sepiteuthis lessoniana) have now been cultured through some successive generations in closed, recirculating seawater systems. The e¡ects of salinity on hatching European Squid (L. vulgaris Lamarck,1798) eggs were investigated during November 2004. The egg capsules were incubated directly in salinity of 32, 34, 36, 38, 40, 42 and 37 g L À1 (control group) at 19.8 1C (SD 1.2 1C), and a photoperiodicity of 12 h light:12 h dark for 16^23 days before hatching. In all treatments, the eggs were developed and hatched normally after 16^22 days at 32 g L À1 , 17^22 days at 34, 18^21 days at 42 g L À1 ,18^22 days at 36 and 40 g L À 1 ,19^22 days at 37 g L À1 and 19^23 h at 38 g L À1 . In the experiments, the highest hatching rate and hatching success (HS) of the eggs were obtained at 38 g L À1 (hatching rate: 100% (SD 0%) and HS: 96.7% (SD 3.5%)) and the lowest hatching rate at 42 g L À1 (hatching rate: 3% (SD 6%) and HS: 0%). Dorsal mantle lengths (DML) of new hatchlings ranged from 2.08 to 2.80 mm. The present study showed that salinity a¡ects the hatching rate and HS of eggs and ¢rst hatching time and DML of paralarvae in L. vulgaris. The squid eggs at stage 11 (I) can tolerate 5 g L À1 reduction and 3 g L À1 increase in salinity.
