摘要: Juveniles of artificially bred Tachypleus tridentatus were reared in the laboratory for 15.5 mo. Fast growth (at least 3 times faster than previous studies) and low mortality observed, with juveniles reaching 9th instar stage having a cumulative 61.3% at end rearing period. Such enhanced can potentially be attributed to high seawater temperature, sufficient living space constant water flow. Isometric prosomal width other parameters including opisthosoma width, eye distance length was found. Two distinct phases detected length, zero from 1st 2nd but isometric stage. Growth telson pos- itively allometric 3rd The increase wet weight throughout 9 developmental stages. Based on patterns, reach adult size within 4 yr. results may serve as basis large-scale culture this species purposes restocking restoration natural populations.
