Temporal and spatial distribution of glochidial larval stages of European unionid mussels (Mollusca: Unionidae) on host fishes.
Glochidia are the larval stage of freshwater unionid mussels that parasitize the fins and gill apparatus of fish. A total of 22 fish species were examined for the presence of glochidia whose distribution on individual hosts was studied on three common fish species, the roach Rutilus rutilus (L.), perch Percafluviatilis L. and bitterling Rhodeus sericeus (Pallas). Between 1997 and 1999, the fish...
متن کاملOn the attraction of larval fishes to reef sounds
Several recent studies have shown that some larval fishes will approach underwater speakers that broadcast reef noise, leading to the hypothesis that larval fishes use acoustic cues to locate reefs for settlement. The purpose of the present study was to examine existing hearing data of fishes in relation to ambient sound levels around reefs to estimate the distance over which reef fish might de...
متن کاملMetabolic rates scale isometrically in larval fishes
We estimated the rate of oxygen consumption of larval Atlantic mackerel Scomber scombrus at 3 temperatures (13, 16, 19 "C) while controlling rigorously for methodological biases. Routine metabolic rates (p1 O2 h-' ind.-l) increase with body weight (W, in mg) and temperature (T, in "C) as: RMR = 2.168 -W1 OoO e0.058 (rZ = 0.96). Thus metabolic rates scale isometrically with respect to body weigh...
متن کاملHistopathology of Some Diseased Fishes
A study on the histopathology of some diseased fishes was carried out during the period from July 2005 to June 2006 in the Institute of Biological Sciences, University of Rajshahi, Rajshahi. Symptoms of diseases of different fish species showed variation among the species and its distribution. The parasites were first found to settled on the body surface and tip of the gills of fishes and attac...
متن کاملPhysiological study of larval fishes: challenges and opportunities
Physiological studies of larval fishes have lagged far behind those of adults, yet offer tremendous opportunities for expanding our knowledge of the basic biology of both marine and freshwater fishes. Physiological studies of larval fishes can also improve research and management in areas of applied science, such as aquaculture, fisheries, and environmental assessment. Additionally, larval fish...
