EFFECTS OF TEMPERATURE ON THE ECOLOGICAL PATTERNS OF RESOURCES RECRUITMENT OF BASTARD HALIBUT, PARALICHTHYS OLIVACEUS (T. ET S.)

The effects of water temperature on early life history patterns of bastard halibutParalichops olivaceus (T, et S.), in the northern China seas were evaluated using the data setsderived from both experimenta trials and field survey. Although the bastard halibut is distributedover the whole waters of China and Japanese seas, the spawning period shortens and the peak ofreproduchon appears later with increase in geographic lahtude, but all offspring occurs in springseason. In accordance with annual data of gonad somahc index, it can be inseminated as a singlemaximum value corresPonding to warming temperature from 9.62 to 19.89℃. ln laboratoryexperimenall trials, eggs can be hatched under the condihon of temperature ranging from 7.0 to27.0℃ and the relation of hatched time (t:hours) to temperature (℃)can be expressed as a negativeexponential funchon as t = 292.84e-0.0968T(r = - 0.864 5, n = 34, p 0.001). However, the mostpeferabe temperaturelies between 15.30 to 17.70t and theoretical hatch time would be 66.59h to52.79h. In association with changes in salinity and temperature, the hatch rate tends to vary with0bivariabe binomial function if salinity is less than 29. The effect of temperature on themetaInorphosis rate of the fish was Positive and total development hme during early life stanzathey size at the end of metaInorphosis has a negahve relahon. For changes in survival durahon (D:d)and temperature (T:℃), the growth in total length can be conceptualized as TL = - l3.598 6 +l.73l T-0. 173D + 0.030 8TX D + 0.002 8D2. It means that maximum growth rate in 1 .217 9 mm / dcan be observed for temperature 23.42℃
