Wash. 66(2), 1999 pp. 101-110 Seasonal Dynamics and Community Structure of Helminths of Spotted Sunfish, Lepomis miniatus (Osteichthyes: Centrarchidae) from an Oligohaline Estuary in Southeastern Louisiana, U.S.A. RlCCARDO A. FlORILLO1 AND WILLIAM F. FONT Department of Biological Sciences, Southeastern Louisiana University, Hammond, Louisiana 70402 U.S.A. (email: raf3@ra.msstate.edu and wffont@selu.edu). ABSTRACT: The seasonal dynamics of the helminth community of the spotted sunfish Lepomis miniatus Warren, 1992, from an oligohaline estuary were investigated over a 1-yr period. From 26 May 1991 to 25 May 1992, 7 helminth species (3 Trematoda, 2 Nematoda, 2 Acanthocephala) were recovered from the gastrointestinal tracts of 200 specimens of L. miniatus. The parasite community of this host was dominated by the trematodes Barbulostomum cupuloris and Genarchella sp. Both helminths were recruited and matured in this host throughout the year, but their times of peak abundance differed. Barbulostomum cupuloris was most abundant in February- May, whereas Genarchella sp. abundance peaked in November-February. Camallanus oxycephalus and Leptorhynchoides thecatus showed a similar pattern of seasonal abundance, which was highest in May-August for both species. The remaining 3 helminths, Crepidostomutn cornutum, Neoechinorhyncus cylindratus, and Spinitectus carolini, were too rare to detect annual patterns of abundance. Infra- and component community diversity and richness did not vary seasonally, but infracommunity predictability was greatest in February-May. KEY WORDS: parasite, helminth, seasonal dynamics, Centrarchidae, Lepomis miniatus, estuary, infracommunity, component community, community, Louisiana, USA. Seasonal fluctuations in prevalence and abundance are common in many helminths of freshwater fishes (Eure, 1976; Chubb, 1979), but the mechanisms influencing seasonality are sometimes difficult to identify. Chubb (1979) concluded that, in general, seasonal patterns of occurrence of helminths are often species-specific and dependent upon: 1) how the helminth invades its host, 2) helminth growth and maturation, 3) accumulation of eggs, and 4) loss of gravid worms. Abiotic factors such as temperature may also affect the seasonal cycles of many helminths (Chappell, 1969; Anderson, 1974, 1976; Eure, 1976; Granath and Esch, 1983a-c). Seasonal patterns of abundance of the helminths of centrarchid fishes in freshwater environments have been previously examined (McDaniel and Bailey, 1974; Cloutman, 1975; Eure, 1976), but studies addressing temporal variability of helminths in nongame centrarchids are lacking. More importantly, the helminth fauna of centrarchid fishes inhabiting estuarine environments has received little attention. Fiorillo and Font (1996) characterized the helminth communities of 4 species of Lepomis from a lowsalinity estuary and showed that the compound 1 Present address of corresponding author: Department of Biological Sciences, Drawer GY, Mississippi State University, Mississippi State, Mississippi 39762. community of centrarchid fishes in brackish water habitats differed from that of centrarchids in freshwater environments. In this study, we examined the seasonal pattern of abundance of all helminths that utilize Lepomis miniatus Warren, 1992, as a definitive host in an oligohaline estuary. In addition, we used community measures to investigate seasonal fluctuations in the infracommunity and component community structure of L. miniatus. Materials and Methods From 26 May 1991 to 25 May 1992, 200 specimens of L. miniatus were collected from a 1.1-km section of a canal along Interstate Highway 55 located between the south bank of Pass Manchac and Ruddock, Louisiana, in St. John the Baptist Parish. This man-made canal is part of the oligohaline Lake Pontchartrain- Lake Maurepas estuary located in southeastern Louisiana. The salinity of this large estuary ranges from 0 ppt at the western shore of Lake Maurepas to 15 ppt at the eastern shore of Lake Pontchartrain, but at our study site, salinity never exceeded 3 ppt. Temporal variation in water temperature was determined using a Datasonde 3® water quality data logger (Hydrolab Corporation, Austin, Texas) located near our study site at the Turtle Cove Research Station on Pass Manchac, Louisiana. Our 1-yr collection period was divided into 4 periods of equal duration. Forty-five specimens were collected during the May-August period (May 26-August 26), 53 during August-November (August 27-November 26), and 51 each during the November—February 101 Copyright © 2011, The Helminthological Society of Washington
