“…As expected, higher temperature caused faster development because it had a direct effect on physiological and biochemical processes [35]. This is a reflection of higher metabolic rate [20] and a decrease in the duration of embryonic or larval development, commonly documented for crustaceans [23]. This effect was previously observed in C. quadricarinatus by [34,36] reported approximately 28 days for egg incubation until hatching at 28°C, which is very similar to the present work.…”

“…In crayfish, time needed for egg development varies with temperature, suggesting the possibility of extending or reducing the incubation period [20]. In crustacean eggs, metabolic rate increases with temperature [21], which affects growth [22], survival [23], and yolk absorption rates [24]. However, high temperature could cause high mortality or serious deformities during egg incubation [25].…”

“…However, high temperature could cause high mortality or serious deformities during egg incubation [25]. Studies on fish [26,27], crustaceans [23,25] and molluscs [28] have shown that there are different approaches to studying the effects of temperature on development. One of the criteria is to measure changes in lipid, protein, and carbohydrate biochemical contents during egg development, which reflect utilization rate [29].…”

Results Organogenesis and morphophysiology of eggs Development of M. idella idella eggs incubated at four different AbstractThe development of M. idella idella eggs incubated at four different temperatures (26, 30, 33 and 36°C). An increase in major axis length was evident at 26, 30, 33 and 36°C. However at 36°C, size variation increased with developmental stages, indicating abnormalities until 192 h, after which total mortality was observed. A distinct change in morphometric parameters (major half axis, minor half axis, area and perimeter) was demonstrated at higher temperatures, irrespective of the developmental duration of eggs. Length of hatched embryos increased with increasing incubation temperatures. Therefore a rapid rate of increase of major half axis and early hatching was observed at 33°C. The larva hatched first in 33°C (241 hrs) then followed by 30°C (265 hrs) and 26°C (302 hrs). In 36°C (182 h) there was total mortality during embryonic development so there was no hatching. temperatures is presented in Plate 1. At 0 h, eggs in all the treatments were in similar phase of development (morula stage) and primodial mesodermal and endodermal cells were visible. After 24 h, the blastocyst was visible in all the four-temperature treatments. Embryos were visible after 48 h in all the treatments. However, abnormal embryonic development was evident at 36°C. At 72 h, the primodial compound eye was visible. At 96 h, a considerable increase in the length of the major axis was seen at higher temperatures (30, 33 and 36°C). At 120 h, star shaped and round protoplasmic islands was visible at 33 and 36°C, respectively and heartbeat was discernible at all temperature treatments. The compound eye with a visible optic lobe was visible at higher temperatures (30, 33 and 36°C). At 144 h, star shaped protoplasmic islands appeared at lower temperatures (26 and 30°C). Rudiments of appendages started developing at all acclimation temperatures. At 168 h, paired compound eyes were visible in all treatments. At 192 h, star shaped protoplasmic islands were seen at lower temperatures (26 and 30°C) while at 36°C, protoplasmic islands appeared was degenerated. After 192 h, complete mortality was noticed at 36°C (Plate 1).At lower temperatures, rudiments of appendages were visible. The primodial digestive canal developed in segments as a dotted line in the posterior region, and appeared to originate from primodial hepatopancreas. The primodial brain was visible at the anterior part of primodial hepatopancreas. The major half axis attained maximum length at the time of hatching. Hatching was initiated by a sudden twitching movement in the posterior region (below the compound eye) by means of the rudimentary antennule. At the time of hatching, telson (or tail) and rudiments of uropod (folded below compound eye) unfolded and the embryonic case was removed from anterior portion by straightening of abdominal segments. Embryos hatched out with a jerky movement and all the anterior appendages in the cephalothoracic region (including walki...

“…Within a tolerated range, temperature mostly affects duration of larval stages, and these effects in turn affect dispersal and gene flow interacting with coastal physical processes (Crisp, 1976). Larval survival is thus strongly affected by temperature and salinity (Sandifer, 1973;Paula et al, 2001a), although each species' tolerance will be specific for its degree of adaptation to the environmental gradients of coastal systems.…”

Abstract-The larval stages of the mangrove crab Parasesarma catenata were reared in the laboratory from eggs of females collected in the Mgazana estuary, South Africa. Survival and duration of larval stages were tested for the combined effects of temperature and salinity in a factorial design experiment, using three females each with two replicates of 15 larvae per combination. Combinations were made from five temperature (15, 20, 25, 30 and 35 ºC) and four salinity values (15, 25, 35 and 45 ‰). Results were tested by ANOVA and multiple regression was applied to generate contour models by polynomial equation. It was found that P. catenata larvae develop optimally in near to seawater salinity at a temperature of around 25 ºC. These results support the assumption that newly-hatched larvae of this species are exported from the estuarine environment to the sea for development.

“…Although some species may have a wide tolerance range and present larval retention inside the estuary (e.g. Antonopoulou & Emson, 1989;Paula, 1993;Munro et al, 1994;Numaguchi, 1998;Verween et al, 2007), many species have to avoid the changing estuarine environment at an early stage by exporting the newly hatched larvae to neritic areas, undergoing most development in seawater and returning to the estuary at the less vulnerable megalopal stage (e.g., Nagaraj, 1992Nagaraj, , 1993Paula et al, 2001Paula et al, , 2003.…”

At a time when global climate changes are forcing life to adapt to a warming and salinitychanging environment, it is essential to understand how future changes in ocean chemistry will affect species. This study evaluates the combined effects of temperature and salinity on survival and development of Upogebia pusilla larvae. Combinations were made from three temperatures (18, 23, and 28°C) and three salinities (15, 25, and 35). Survival, larval duration and megalopa size were compared between treatments. U. pusilla larvae developed optimally in the highest salinity (35) and higher temperatures (23-28°C). Low salinities and temperatures did not support larval survival and development, with salinity being the main restricting factor for survival, while temperature affected mainly the duration of the larval stages. Larvae at higher temperatures (23-28°C) presented a higher development rate but no differences were found in megalopa size.
