<em>Eustrongylides</em> spp. is considered a freshwater fish zoonotic nematode. In the present study, the prevalence of <em>Eustrongylides</em> spp. in six edible fish (European perch - <em>Perca fluviatilis</em>, goldfish - <em>Carassius auratus</em>, largemouth black bass - <em>Micropterus salmoides</em>, tench- <em>Tinca tinca</em>, carp - <em>Cyprinus carpio</em> and sand smelt - Atherina boyeri) of Trasimeno lake was surveyed. The investigations were conducted from October 2014 to September 2015 and 384 specimens per species for each season were caught in Trasimeno lake and examined for the presence of larvae in the abdominal cavity and muscle. The presence of nematodes in the abdominal cavity and musculature was revealed in three fish species. The prevalence of Eustrongylides spp. infection was 6.84, 1.89 and 0.13% in perch, largemouth black bass and sand smelt, respectively. The number of parasites per fish was only one in largemouth black bass and sand smelt and ranged from one up to three in perch. This study states that the European perch, largemouth black bass and sand smelt of Trasimeno lake are infected with zoonotic parasites; therefore, food business operators have to take appropriate measures to guarantee the health of consumers.

Aquaculture Facilities

The black bass, Micropterus salmoides, was introduced to Brazil from North America in 1922. Since then the species has been reared in aquaculture facilities intended to stock reservoirs as additions to native stocks available for angling. At present no scientific information on the biology of black bass in Brazilian waters is available. Since black bass dispersion may cause severe impacts on native Brazilian fish fauna, information on the basic biological parameters of this species is necessary. The objective of the present study is to provide information on the growth, age structure, and mortality of the species in a small reservoir in southern Brazil, where the species reproduces regularly. Based on scale readings, the von Bertalanffy growth curve was calculated and compared to the length-frequency distribution of the population. Both methods showed similar results. Maximum length was about 44 cm. The mean length at the end of the first year was 23.1 cm (s.d. = 13.88); at that of the second, 37.3 cm (s.d. = 12.52); and 41.4 cm (s.d. = 9.92) at the third. Oldest fish were three years old. The growth performance index ø' was 3.28 cm year-1. Mortality increased from 0.16 year-1 between the first and the second cohort, to 0.8 year-1 between the second and third. The results show that black bass in Brazil grows faster than in its area of origin, but longevity is shorter and body shape, stouter. The cause of high mortality at a relatively early age may be connected with the loss of genetic diversity due to inbreeding of the Brazilian stocks, which originated from few introduced individuals a long time ago. The fact that black bass reproduces in reservoirs and grows rapidly may be considered a threat to conserving fish diversity in Brazilian ecosystems.

1. The scale method of age determination in largemouth black bass, Micropterus salmoides, is valid at least up to and probably including the third year of the fish's life. A more careful study of older fish might reveal that it was valid beyond that point. 2. The annulus in a largemouth black bass is formed by a brief but gradual slowing down of growth and then its quick resumption. The annulus appears as a wide band on the anterior edge of the scale, and as a dark line (circulus) cutting across some inner dark lines (also circuli) on the lateral edges. 3. The scale is mesodermal in origin, and lies in a pocket surrounded by dermal tissue, which in turn is covered externally by a thin layer of epidermis. 4. The bony layer is formed by osteoblastic cells on its outer surface in a manner similar to the formation of dermal bone. Excess bony material is accumulated in ridges or circuli. 5. The fibrillary plate is formed by the fibroblastic cells on its inner surface.

<em>Abstract</em>.—In Lake Martin (16,000 ha), Alabama, black bass <em>Micropterus </em>spp. tournaments occur nearly every weekend at a single site (Wind Creek State Park [WCSP]), which could cause fish to accumulate at this release site and potentially cause negative impacts to the population. Over a 7-month period, nearly 6,600 tour-nament-caught largemouth bass <em>M. salmoides </em>and spotted bass <em>M. punctulatus </em>were injected with a coded wire tag at different body locations before release at WCSP. After release, black bass were collected with electrofishing up to 1.5 years following release at 0–10 km from the release site and scanned for a tag. Although variable, a substantial proportion (10–70%) of tournament-caught black bass comprised the black bass population within 3 km of WCSP up to 3 months after release. After 3 months, proportions of tagged black bass within 10 km of WCSP decreased dramatically and by an order of magnitude after 1 year, which strongly suggested that these fish dispersed from WCSP. Over a 2- to 70-d period after release from a tournament, relative weights of tournament-released black bass were typically less than fish not released in tournaments. In addition, we collected and aged black bass throughout Lake Martin; relative weights of both black bass species were less and spotted bass growth was lower within 10 km of WCSP compared to other regions of Lake Martin. Even though black bass dispersed from the WCSP release site, these negative population effects were attributed to the constant translocation and accumulation of tournament-caught fish in this region of Lake Martin. In water bodies such as Lake Martin where mass translocation of black bass occurs annually at a single site, the use of live-release boats to transport tournament-caught black bass and the promotion and use of alternative release sites should be encouraged to reduce possible localized negative population effects.
