“…Most cancrid crabs are found in cold temperate and boreal waters (MacKay, 1943) and provide a huge proportion of crustacean fisheries in those regions (Bennett, 1995;Johnson and Shanks, 2002). Due to their commercial importance population structure and recruitment of cancrid crabs have been the subject of several studies (e. g. Hankin et al, 1997;Eaton et al, 2003;Taggart et al, 2004;Fischer and Thatje, 2008;Fischer et al, 2009).…”

a b s t r a c t a r t i c l e i n f oTemperature changes during ENSO cause mass mortalities of adult Cancer setosus, but the effects on early life stages are unknown. The influence of temperature on survival, development and biochemical composition was studied in larvae of the hairy crab, C. setosus, from a population off the northern Chilean coast. In rearing experiments conducted at four different temperatures (12, 16, 20, 22°C), zoeal development was only completed at 16 and 20°C, after 78 and 36 days, respectively. Instar duration was negatively correlated with temperature. A multiple linear model relating larval body mass (in carbon) to temperature and developmental time suggests that successful larval development is possible within a narrow temperature range only. The biochemical composition, measured as carbon, hydrogen, and nitrogen (C, H, N) content, show in general the typical oscillating changes during the moult cycle of brachyuran crab larvae. However, at high (22°C) and low (16°C) temperatures, CHN values show deviations from the typical pattern, indicating threshold temperatures for larval activity and survival. These findings indicate that the larval development of C. setosus is compromised under conditions of El Niño, with temperatures exceeding the upper thermal temperature tolerance threshold of larvae. Effects of El Niño on early life history stages and recruitment rates should be increasingly taken into account in fisheries management strategies.

“…Most of the 24 extant species of cancrid crabs (Nations, 1975(Nations, , 1979Carvacho, 1989) are found in cold temperate and boreal waters of the Pacific and Atlantic Oceans (MacKay, 1943). Their reproductive cycles follow seasonal changes in temperature and food availability in these regions.…”

Ovigerous females of Cancer setosus are present year-round throughout most of its wide range along the Peruvian/Chilean Pacific coast (2°S-46°S). However, their number of egg-masses produced per year remains speculative and as such has neither been considered in latitudinal comparisons of reproduction, nor for its fisheries management. In order to reveal the effect of temperature on egg-mass production and eggdevelopment, female C. setosus were held in through-flow aquaria under natural seasonal temperature conditions (16-23°C) in Antofagasta (23°S), Northern Chile (05/2005-03/2006; 10 months), and at three constant temperatures (12, 16, 19°C) in Puerto Montt (41°S), Central Southern Chile (09/2006-02/2007; 5 months). Female crabs uniformly produced up to 3 viable egg-masses within 4 1/2 months in Antofagasta and in Puerto Montt (at 19°C). The second egg-mass was observed 62.5 days (± 7.6; N = 7) after the oviposition of the first clutch and a third egg-mass followed 73.5 days (± 12.5; N = 11) later in Antofagasta (at 16-23°C). Comparably, a second oviposition took place 64.4 days (± 9.8, N = 5) after the first clutch and a third, 67.0 days (± 2.8, N = 2), thereafter, at 19°C in Puerto Montt. At the two lower temperatures (16 and 12°C) in Puerto Montt a second egg-mass was extruded after 82.8 days (± 28.9; N = 4) and 137 days (N = 1), respectively. The duration of eggdevelopment from oviposition until larval hatching decreased from 65 days at 12.5°C to 22.7 days at the observed upper temperature threshold of 22°C. Based on the derived relationship between temperature and the duration of egg-development (y = 239.3175e − 0.107x ; N = 21, r 2 = 0.83) and data on monthly percentages of ovigerous females from field studies, the annual number of egg-masses of C. setosus was calculated. This analysis revealed an annual output of about one egg-mass close to the species northern and southern distributional limits in Casma (9°S) and Ancud (43°S), respectively, while at Coquimbo (29°S) about two and in Concepción (36°S) more than 3 egg-masses are produced per year.

“…Cancer species have long been the subject of intense interest from evolutionary biologists, paleontologists, and systematists (Bell, 1835;Weymouth, 1910;Way, 1917;Imaizumi, 1962;Nations, 1975Nations, , 1979Carvacho, 1989), behavioral ecologists (Mackay, 1943;Garth and Abbott, 1980;Orensanz and Galluci, 1988;Creswell and McLay, 1990;Orensanz et al, 1995), and fisheries researchers (e.g., Anderson and Ford, 1976;Haeffner, 1976;Reilly and Saila, 1978;Ingle, 1981;Carroll, 1982;Lawton and Elner, 1985;Hines, 1991), and as a result, there exists a plethora of ecological, behavioral, and biogeographic information on the genus. Despite the ecological, evolutionary, and economic importance of Cancer crabs, phylogenetic hypotheses for the analysis of their evolution and adaptations have yet to be developed and their diversity has yet to be examined in a temporal or comparative context.…”
