“…Larval development in crabs is temperature related, with an increase in temperature resulting in shorter development times (Nakanishi, 1981;Vinuesa et al, 1985;Anger, 1993;Okamoto, 1993;Anger et al, 2003;Walther et al, 2010). Less time spent in the plankton as vulnerable larvae may also increase survival rates to final instars and eventually adults, thus potentially increasing the size of the population.…”

The effect of temperature on brood duration in three Halicarcinus species (Crustacea: Brachyura: Hymenosomatidae)

et al. 2011

The effect of temperature on brood development was investigated for three intertidal hymenosomatid crabs: Halicarcinus cookii, H. varius and H. innominatus in Kaikoura, New Zealand. The duration of brood incubation decreased as temperature increased, as did the interbrood period. The duration of each stage of brood development also decreased with increased temperature, but the proportion of total incubation time for each stage remained relatively similar at different temperatures. Hymenosomatid crabs have determinate growth, but moult to maturity at different sizes, thereafter devoting most of their energy to reproduction. The number of broods a female could carry in her lifetime was estimated for each species. Halicarcinus cookii was estimated to be able to produce eight complete broods of 1146 eggs per lifetime, H. varius was estimated to be able to produce seven complete broods of 1051 eggs per lifetime and H. innominatus was estimated to be able to produce six complete broods of 1081 eggs per life time. With the predicted global temperature rise of 28C in the next 50 years, the authors estimate that, for all three species, a female could produce one extra brood per lifetime (a 10-15% increase in fecundity depending on species), even more if crabs reach maturity faster, potentially leading to a significant population increase.

The combined effects of predicted ocean acidification and global warming on the larvae of the cold-eurythermal spider crab Hyas araneus L. were investigated in 2 populations: a southernmost around Helgoland (North Sea, 54°N) and a northernmost at Svalbard (North Atlantic, 79°N). Larvae were exposed at temperatures of 3, 9 and 15°C to present day normocapnia (380 ppm CO 2 ) and to CO 2 conditions predicted for the near or medium-term future (710 ppm by the year 2100, 3000 ppm by 2300 and beyond). Larval development time, growth and C/N ratio were studied in the larval stages Zoea I, II, and Megalopa. Permanent differences in instar duration between both populations were detected in all stages, likely as a result of evolutionary temperature adaptation. With the exception of Zoea II at 3°C and under all CO 2 conditions, development in all instars from Svalbard was delayed compared to those from Helgoland. Most prominently, development was much longer and fewer specimens morphosed to the first crab instar in the Megalopa from Svalbard than from Helgoland. Enhanced CO 2 levels (particularly 3000 ppm) extended the duration of larval development and reduced larval growth (measured as dry mass) and fitness (decreasing C/N ratio, a proxy of the lipid content). Such effects were strongest in the zoeal stages of Svalbard larvae, and during the Megalopa instar of Helgoland larvae. The high sensitivity of megalopae from the Svalbard population to warming and of those from Helgoland to enhanced CO 2 levels suggests that this larval instar is a physiologically sensitive bottleneck within the life cycle of H. araneus.

“…Sulkin and McKeen considered the final zoeal stage of Cancer magister to be the most sensitive to temperature stress and P. gigas appears to be similar as mortality was highest at this stage (Sulkin and McKeen, 1989). The incidence of deformity increases at extreme high temperature in most organisms (Battle, 1930) and this appeared to contribute to the low survival of megalopa typical at high temperatures (Okamoto, 1993). Johns (Johns, 1981) noted that larval size of Cancer irroratus was greatest in the mid-range of thermal tolerance, although larval weight more typically declines with increased temperature (Shirley et al, 1987;Sulkin and McKeen, 1994), as was observed with P. gigas.…”

Pseudocarcinus gigas is a deep-water commercial species. To date, only three larvae have been collected, despite extensive sampling. Therefore, to assist the targeting of field sampling of larvae, laboratory-based research was undertaken to identify temperature preferences. Two approaches were taken. The first investigated the behavioural responses of P. gigas larvae to temperature. Experimental columns with discontinuous temperature gradients were used to test the ability of P. gigas larvae to penetrate thermoclines vertically. Each trial also presented the larvae with a choice of two temperature options so results were used to infer preferred temperature ranges. In the second approach, we measured instar duration, somatic growth and survival of larvae reared at 12 temperatures between 10.5 and 21.1 C. Behavioural experiments indicated that zoeas I and II could readily penetrate experimental thermoclines of $2, 5 and 10 C. Upward swimming was induced in water temperatures 12.7 C and downward swimming or passive sinking induced by temperatures !16.2 C. Intermoult duration decreased with increasing temperature, although more rapid development was at the expense of somatic growth. Apparent temperature preferences of larvae from behavioural trials were also optimal for survival and growth. No larvae survived to megalopa in those treatments below the threshold temperature where upward swimming was induced in behaviour trials. Many megalopas died shortly after moulting from zoea V, particularly in treatments with rapid development (>16.8 C) and above those temperatures where downward migration of zoeas was induced. Highest abundance of P. gigas larvae in the field is predicted to be in water of 13-16 C.
