| Abstract: | Basic biological investigations on the intertidal amphipod Parhyale basrensis are made. The incubation period is 1–2 weeks. The generation time is 5–6 weeks. Females produce at least 4 broods before they die. The number of eggs carried by the female is a linear function of size of the female. Egg numbers varies from 4–37. Maturity occurs at a size of 4 mm for the female and 4·5 mm for the male. The breeding season is extending from late February to late November or December. Recruitment starts at the beginning of May. Successive broods may have different life spans. The maximum life span of the population is 13–15 months and the minimum life span is 6–7 months. |
