Oryzias woworae is one of Muna Island's endemic fish, Sulawesi, which needs to be developed in cultivation and can be used as ornamental fish with high economic value. However, information on fish farming is not yet well available, especially at egg incubation temperatures. This study aims to determine the optimal temperature of the incubation water medium for the hatching performance of O. woworae eggs. The study used experimental methods with the treatment of differences in egg incubation temperatures at 24-26°C (temperature fluctuations in the laboratory), 24°C, 28°C and 32°C. The research parameters were analyzed descriptively, namely embryogenesis, hatching time, and hatching rates. The results showed that differences in incubation temperature affected the embryogenesis of O. woworae eggs. The obtained fastest time for hatching eggs O. woworae at a temperature of 32°C with six days 5 hours 49 minutes and 100% hatching. The egg incubation temperature 24-26°C is the lowest hatching time and hatching rate, nine days 11 hours 38 minutes and 53.33%. The use of 32°C in the incubation medium is the optimal temperature to accelerate embryogenesis and the hatching rate of O. woworae eggs.

Groupers were known as a high economically marine commodity and in order to support groupers production, the seed availability was the most important. Eggs are still as limited factor in hatchery production, for this reason the success of eggs transportation is one as base of successful production of seed. Planning on hatching time of eggs through different incubation temperature was an option to solve that problem. This experiment was aimed to find out the optimum temperature for groupers eggs and the minimum temperature to arrange incubation time and to plan the hatching time. Fertilized eggs were incubated into three beaker glasses of 1 liter in volume with the density of ± 250 eggs/liter. The incubation was done under laboratory condition at controlled temperature, i.e. (A) 21-22 ºC, (B) 24-25 ºC, (C) 27-28 ºC and (D) 30-31 ºC. The eggs that used were including orange spotted grouper (Epinephelus coiodes), brown marbled grouper (E. microdon), tiger grouper (E. fuscoguttatus) and humpback grouper (Cromileptes altivelis). Investigated variables were embryonic development pattern, incubation time and hatching rate. The result showed that the eggs incubated in temperature range of 24-31°C had the normal sequence of embryonic development pattern, but in temperature of 21-22°C performed irregular sequence and the embryonic development stopped at blastula or gastrula stage or even the eggs could still develop but the body of hatched larvae were abnormal. In lower temperature incubation, the incubation time was longer and the hatching rate of eggs was lower than those in higher temperature. Therefore the optimum temperature for incubation of orange spotted grouper, marbled grouper, tiger grouper and humpback grouper eggs ranged between 24-31 ºC, while the lowest possible temperature was 24 ºC.Keywords: incubation temperature, embryonic development pattern, grouper eggs, hatching rate

Snapping turtles (Chelydra serpentina) demonstrate temperature-dependent sex determination (TSD): intermediate egg incubation temperatures (23-27 degreesC) produce males, while extreme temperatures produce females. Snapping turtles are also sexually dimorphic: adult males are typically larger than females. Previous researchers hypothesized that male-producing egg temperatures enhanced the growth rate of juvenile turtles, resulting in the adult dimorphism and potentially providing an adaptive benefit for TSD. In reptiles, the choice of ambient temperature can also influence growth. I measured the effect of egg incubation temperature on juvenile growth rate and water temperature choice of C. serpentina. Eggs were incubated in the laboratory at 21.5, 24.5, 27.5 or 30.5 degreesC to produce both sexes, all males, both sexes or all females, respectively. Egg temperature was linearly and negatively correlated with growth rate of both male and female juveniles. Thus, growth was enhanced, but not maximized, by male-producing egg temperatures. Egg temperature was also negatively correlated with juvenile temperature choice such that, on average, turtles from 21.5 degreesC eggs selected 28 degreesC water, while turtles from 30.5 degreesC eggs chose 24.5 degreesC water. Additionally, these temperature choices were highly repeatable, even following a 6 month hibernation period at 7 degreesC. Thus, while male egg temperatures do not directly maximize growth, multiple effects of embryonic temperature may combine to create long-lasting differences in the behavioral physiology of male and female C. serpentina. Such differences could be important to the ecology and evolution of TSD.

SummaryTemperature is an environmental factor that influences the development of fish, and when changed abruptly can lead to high mortality. Some species of fish are influenced by this factor, exhibiting a longer time for embryonic development and time to first feeding. This study aims to evaluate the effect of water temperature on embryonic and larval development up to first feeding, to describe the time in hours post fertilization (hpf) of the emergence of different structures and to determine the best hatching rate and survival of animals under different treatments. Five different egg incubation temperatures were used (24, 26, 28, 30 or 32°C, respectively). The eggs were observed at regular intervals of 30 min up to 24 h, every 2 h until 48 h and every 4 h until the display of first feeding in all treatments. Embryonic development was longer for eggs incubated at 24°C and the best results for hatching rate and survival of spawning efficiency were at 28°C. We recommend that incubation of Trichogaster leeri eggs is carried out at 28°C up to the first feeding of larvae.

In seed production, the success of spawning and egg production is very important to mantain the cultivating sustainability. The quantity and quality of the blacksaddled coral grouper eggs should be properly manipulated to produce the higher values. The purpose of this study was to determine the effect of different temperatures on the results of hatch success (embryo development, incubation time, hatching rate and larvae abnormality). The eggs used were obtained from natural spawning and collected with egg collector. The fertilized eggs were incubated in four pieces of container and were treated with different temperatures of 26°C, 28°C, 30°C, and 32°C which each treatment was repeated 3 times. The incubation equipment with automatic temperature control was used in this treatment. The results showed that the eggs which were incubated at 32°C produced a faster of embryonic development and hatch within 14 hours while the temperature of 26°C took 18 hours to hatch. However, the temperature of 32°C resulted in low egg hatchability, with 60.29%, as well as the abnormalities of 8.42%. The best temperature of each treatment was obtained at the incubation temperature of 30°C, whereas the phase of the hatch was achieved within 15 hours, with egg hatchability of 92.25% and the abnormality of 6.29%. From these results, it can be concluded that the optimum incubation temperature for Blacksaddled coral grouper was 30°C.

With data assembled from the literature, relations are examined between incubation temperature and rate of development from fertilization to hatching for chinook salmon (Oncorhynchus tshawytscha) eggs. Ten forms of three empirical relations are used, based on the thermal sums hypothesis, Bělehrádek's equation, and a form of the logistic curve. In each case comparisons are made using constant, ambient, and combined (constant + ambient) incubation temperatures. In most cases the rules of minimum variance curve fitting are somewhat violated, although results using the log-inverse form of Bělehrádek's equation are superior to those from the other models. Early imposition of low, constant incubation temperatures (below 6–7 °C) appears to slow egg development below those rates occurring at ambient temperatures having the same mean values. Time–temperature relations based on the unmodified thermal sums hypothesis and its associated "degree-days" are compared with predicted values obtained using the log-inverse Bělehrádek model as a standard. The former model tends to underestimate the length of the incubation period by an average of about 5 days at incubation temperatures above 4 °C; below 4 °C the former model increasingly overestimates the incubation period. Based on the log-inverse Bělehrádek model, a table is provided of predicted daily rates of development in relation to temperature. The table may be used to predict hatching time in a manner similar to that employing degree-days. In general, the enquiry points to a lack of data on development time at temperatures below 5 °C; to be meaningful, further analyses will require such data. Key words: prediction, modeling, development rates, hatching time
