内容記述 |
Responses of eggs of the threeline grunt, Paraplistipoma trilineatum, to a series of temperature-salinity combinations were measured for percent of total hatching and rate of development in a temperature range of 12 - 32℃ and a salinity range of 29.0 - 36.2 ‰. Hatching occurred at temperatures ranging from 18 to 28 ℃ combined with salinities ranging from 31.0 to 36.2 ‰. Response surface analysis suggests that the maximum hatching percent ( i.e.,optimum) may be found at 22.4 ℃ and 34.2 ‰, and that the isopleth of 90 % hatching is bounded on temperatures of 19.5 and 25.4 ℃ and on salinities of 32.1and 36.3 ‰. The threeline grunt eggs are considered to be stenothermal and stenohaline. The surface also indicates the possible existence of a low / low - high / high interaction between the two variables. Time required to 50 % hatching varied between 15.0 and 46.8 hrs (about 17 and 49 hrs after fertilization) for the combinations within which the range of hatching occurred. The time was inversely and exponentially related to temperature. The regression line for plots log time against temperatures consisted of the two straight components, intersecting in the vicinity of temperature at the time of spawning The values of temperature characteristics such as Q10 and µ were higher at the lower temperatures. The effects of salinity on the time to hatching were small in comparition with those of temperature, though both the increasing and decreasing from 32.6 ‰ have a tendency to produce a progressive retardation of the development. Little interaction effect was seen between the two variable. Of the time neccessary for the attainment of various developmental stages, each regression line in the relationship between time and temperature was essentially parallel to that of the time to 50 % hatching. The rate of differentiation up to hatching seems to be governed by one process throughout. |
