“…Despite the release of bopyrid larvae by adult parasites, the absence of newly infected shrimp during the experimental period can be explained by the use of artificial seawater that lacked calanoid copepods, which act as intermediate hosts (Dale & Anderson 1982).…”

“…The life history of bopyrid isopods can be briefly described by the existence of a free swimming epicaridean larva that attaches itself to a calanoid copepod, which acts as an intermediate host. The larva metamorphoses into a microniscus (Dale & Anderson 1982), which remains on the host copepod until metamorphosing into a free swimming cryptoniscus larva. The cryptoniscus eventually leaves the copepod, becoming the infective stage of the definitive host.…”

“…After B1-2 weeks, the parasite emerges into the host branchial chamber (Anderson 1990), attaches to the shrimp's branchiostegite as an ectoparasite, and then becomes an adult female (Anderson 1975;Overstreet 1978;Dale & Anderson 1982;O'Brien & Van Wyk 1985). Subsequent cryptoniscus larvae that enter the branchial chamber of already infected hosts will attach to the female parasites, never becoming endoparasites (Anderson 1990), and will become males (Anderson Parasitism in amphidromous shrimps 347 1975;Overstreet 1978;Dale & Anderson 1982;O'Brien & Van Wyk 1985) within 24 h after contact with the females (Anderson 1990). A male may remain with the same female, and thus host, throughout its lifetime (Cash & Bauer 1993).…”

Infection of adult migratory river shrimps, Macrobrachium ohione, by the branchial bopyrid isopod Probopyrus pandalicola

Abstract. Macrobrachium ohione is a migratory (amphidromous) river shrimp (Decapoda, Caridea) that may be parasitized by the branchial parasite Probopyrus pandalicola (Isopoda, Bopyridae). The parasite disrupts gonadal maturation and spawning in female shrimps, resulting in the total loss of reproduction. Shrimps are usually infected by bopyrid parasites during the late zoeal or early postlarval stages; in this study, we investigated the apparent parasite infection of adult shrimps. We analyzed the relationships between parasite body size (total length) and host shrimp body size (carapace length) to test the hypothesis that parasite infection of adult shrimps occurs during the shrimps' reproductive migrations. The results presented here indicate that infection of adult shrimps is common in M. ohione in the Atchafalaya and Mississippi Rivers, Louisiana, USA. In the two upriver sites sampled, Butte La Rose (BLR) and River Bend (RB), parasite size was not associated with host body size. In these locations, many parasitized adult M. ohione were infected with immature P. pandalicola (40.3% in BLR and 51.2% in RB), indicating that the shrimps were adults at the time of infection. A possible explanation is that when female shrimps enter the estuary to hatch larvae, they molt and spawn another brood. The smaller male shrimps that accompany the females downstream are also assumed to molt and continue growth. The intermediate host of the parasite is an estuarine copepod, and thus the parasite cryptoniscus larva that infects the host shrimp is primarily estuarine as well. Newly molted shrimps have soft cuticles, which may facilitate their infection by parasite cryptonisci. Our conclusion is that most infections of adult shrimps occur during their migration into estuarine waters, the primary habitat of infective parasite larvae, and that host vulnerability is probably increased following host ecdysis.
