E. ingens was found on about 1% of banana prawns, P. merguiensis, from the south-eastem corner of the Gulf of Carpentaria, but was absent from prawns taken north of the Staaten River. Prawns evidently became infected when they were juveniles in the estuaries, as there was a strong correlation between parasite length and host length and no immature parasites were found on adult prawns. The bopyrid is apparently long-lived and thus makes a convenient biological marker for prawns coming from the south-eastem estuaries. Extensive migrations of adolescent banana prawns appeared unlikely as nursery rivers contributed prawns to adjacent offshore grounds.

Parasites in banana prawns, P. merguiensis, from the Gulf of Carpentaria were surveyed. Only the lecanicephalid cestode Polypocephalus sp. seemed useful as a biological marker for banana prawns. Loads of Polypocephalus sp. were low and constant at salinities from 14 to 34. At higher salinities (38), both intensity and prevalence of infection rose markedly from 0.5 Polypocephalus sp. per prawn and 27% to 6.25 and 95%, respectively. The frequency distribution of Polypocephalus sp. was adequately described by a non-truncated form of the negative binomial distribution (n = 943, p = 35.4, k = 0.43) suggesting there were no parasite-induced mortalities. Loads of Polypocephalus sp. in prawns in the commercial catch from Albatross Bay were most similar to loads in prawns from the Mission River, which empties into Albatross Bay. Polypocephalus sp. loads in Penaeus merguiensis formed two other natural groupings, one in the south-east corner of the Gulf and one in the Cape Keerweer-Mitchell River area. There was no parasitological evidence for extensive migrations of adolescent P. merguiensis away from their nursery estuaries.

Penaeus Merguiensis

Recruitment patterns of postlarvae immigrating into mangrove nursery areas of five major estuaries around the south-eastern Gulf of Carpentaria, as well as juveniles emigrating offshore into coastal waters, were compared for the banana prawn, Penaeus merguiensis, from September 1978 to March 1979.. Although considerable variability was observed among rivers, some basic recruitment patterns were discernible. Recruitment of postlarvae tended to follow a 28-day cycle with increased immigration on alternate spring tides. Variability between rivers in the number of resident juvenile prawns at any one sampling time resulted mainly from differences in the relative magnitude of postlarval settlement from these monthly cohorts. After the first heavy rainfall of the monsoon season, the lower reaches of rivers with !xger catchment areas a!! ran fresh, setthg up a physica! barrier to further past larval immigration. In contrast, post larval immigration continued throughout the study period in the river with the smallest catchment. There was a trend for more successful immigration earlier in the more northern rivers. Offshore emigration was influenced by rainfall, tide height and number of resident juvenile prawns at the time of emigration. The relative importance of these three factors differed among rivers, depending on the timing of rainfall in relation to the timing of juvenile population changes and the degree of flooding. These local differences in the timing of emigration of juveniles could be detected in the abundance and size of adolescent prawns in the offshore coastal area of the south-eastern Gulf which in turn influenced the size composition of prawns available to the commercial fishery.
