To describe the growth pattern of bonnethead shark (Sphyrna tiburo) in Gulf Mexico, a von Bertalanffy (VB) model has been automatically fit, which indicated single−phase continuous without oscillations, though this would generate biases if hypothesis is not confirmed. The objective research was to S. tiburo under multimodel approach based on information theory and contrasting models (VB, Gomper...

Parasites of the fathead minnow, Pimephales promelas, were examined in fish collected from Elk Creek (40.88534 degrees N, 96.83366 degrees W) and West Oak Creek (40.90821 degrees N, 96.81432 degrees W), Lancaster County, Nebraska. These 2 streams are part of the Salt Valley watershed and flow together approximately 2 km downstream from the collection sites to form Oak Creek. This study examined...

Wildlife provisioning is popular, economically valuable, and a rapidly growing part of marine tourism, with great potential to benefit conservation. However, it remains controversial due limited understanding its implications on the behavior ecology target species. In this study, we modeled how various abiotic biotic factors influenced hammerhead sharks’ ( Sphyrna mokarran ) use recreational di...

The representatives of the class Monogenea are great importance in fish pathology. Dactylogyrus vastator (Nybelin 1924) (Monogenea: Dactylogyridae) is a common pathogenic monogenean parasite carp (Cyprinus carpio Linnaeus, 1758) from freshwater lakes and cyprinid ponds, worldwide. In our study, total 133 specimens cage culture system on Mladost Reservoir (N. Macedonia) were subjected to parasit...
