“…An exponential increase in development time with a corresponding decrease in temperature is well supported in the literature. The calanoid copepod, Pseudocalanus newmani, was reported to experience a doubling of development time from 20.9 to 42.3 days when temperatures decreased from 15 to 6°C (Lee et al, 2003). This trend was also observed in A. clausi, where development time increased from 35.4 to 74.8 days when temperatures decrease from 10 to 5°C.…”

Four experiments were conducted on the calanoid copepod, Pseudodiaptomus pelagicus, to determine the effects of temperature (24, 26, 28, 30, 32, and 34°C) on survival, development time, reproductive output, and population growth in order to define the optimal temperature for culture. The first experiment stocked early stage nauplii into 1 L beakers and cultured them using standard procedures until five days after the first mature adults were observed; from this survival, sex ratio, time to maturation, and fecundity were measured. The second and third experiments evaluated the effects of temperature on nauplii production by stocking individual pairs and 25 pairs of adults, respectively; in both experiments nauplii production was determined daily for 10 days. The fourth experiment determined the effects of temperature on population growth and composition of the population produced by stocking 10 adult pairs and culturing them for 10 days at six temperatures. Results indicate survival from early nauplii to adult was significantly affected by temperature and those cultured from 24-30°C had the highest mean survival. Time to first maturation and maturation of the entire population was significantly influenced by temperature and took from 6.8 to 12.8 days. Temperature significantly affected nauplii production in both individual and groups of paired adults. Temperature affected the mean daily nauplii production by decreasing the brood interval but did not affect the mean brood size. The number of nauplii produced by 25 adult pairs was significantly influenced by temperature; the optimal temperature was 27.5°C at which 1861 nauplii were produced. The distribution of developmental stages in the population was also affected by temperature; at lower temperatures the population consisted of a greater proportion of nauplii while at 32°C the population was comprised of more advanced staged individuals. When developing production objectives, aquaculturists must consider temperature because it has multiple effects on the culture of P. pelagicus. The optimal temperature range to achieve high survival and the greatest nauplii production is 26-30°C. To maintain long-term stock cultures the best temperature may be 24°C to slow maturation and growth while 28-32°C may be used to maximize nauplii production by decreasing time to maturation and decreasing brood intervals.

“…Because of the increase of phytoplankton availability as food, the survival rates of each stage in copepods would have increased (VanderLugt 2005, Almeda et al 2010, Santhanam & Perumal 2012. The generation time of these copepods is generally from 15 to 25 days in water temperatures between 15°C and 20°C (Jacobs 1961, Vuorinen 1982, Landry 1983, Uye 1988, Huntley & Lopez 1992, Calbet & Alcaraz 1997, Lee et al 2003. Therefore, the high Chl a concentrations during the upwelling periods in the present study might have potential for promoting increases of copepod abundance.…”

Copepods were collected using a Norpac net (0.315 mm mesh aperture, 0.45 m mouth diameter) in the summers from 1992 to 2010 at Stn A (700 m depth) in Tosa Bay, western Japan. Among the summer samples collected in July and August, there were 19 net samples during periods of upwelling and 27 net samples during periods of nonupwelling, judged by criteria of water temperature. Total abundance of adult copepods in the upwelling samples was not significantly different from the abundance in the non-upwelling samples, while the number of species and species diversity in the upwelling samples was lower than in the non-upwelling samples. Adults of four species (Calanus sinicus, Clausocalanus parapergens, Paracalanus parvus s.l. and Corycaeus affinis) in the upwelling samples were significantly more abundant than those in the non-upwelling samples. The changes of the copepod community structure during periods of upwelling may be produced because of increases of species preferring low water temperatures and decreases of species preferring warm water temperatures.

“…and Neocalanus spp. ), results from Sabatini & Kiør-boe (1994) for Oithona spp., and equal stage durations (isochronality) for Pseudocalanus spp., which approxi mates the results of Lee et al (2003). A number of studies published Belěhrádek functions rather than raw development-time data (Table 1), and in these cases, we simply use the fit as if it were data, across the particular temperature range where it was defined.…”

A new synthesis of laboratory measurements of food-saturated development and growth across diverse copepod taxa was conducted in a theoretical framework that distinguishes general allometric constraints on copepod physiology from contingent strategies that correlate with size for other reasons. After temperature correction, the allometry of growth rate is inconsistent between the ontogeny of Calanus spp., where it follows the classic −0.3 power-law scaling, and a broader spectrum of adult size W a (0.3 to 2000 μg C, Oithona spp. to Neocalanus spp.), across which the classic scaling appears to represent only an upper limit. Over the full size spectrum, after temperature correction, a growth rate g 0 relative to the −0.3 power law correlates with adult size better than does relative (temperature-corrected) development rate u 0 ; in contrast, at a finer scale of diversity (among Calanus spp., or among large (> 50 μg C) calanoids in general), u 0 is the better correlate with adult size and the effect of g 0 is insignificant. Across all these scales, the ratio of relative growth and development rates g 0 /u 0 is a better predictor of adult size than g 0 or u 0 alone, consistent with a simple model of individual growth.
