Studies of the kinematics of the pectoral fins in fishes have focused on fins as devices for propulsion or maneuvering. Studying pectoral fin function in benthic fishes is an opportunity to understand how the fins are used in a broader range of fin-based behaviors, especially those involving substrate contact. Morphological specializations of the pectoral fins, hypothesized adaptations for subs...

In case of automobile the fuel saving is the prime important with minimum emission and best performance. The phenomenon by which heat transfer takes place through engine fins must frequently be improved for these reasons. Air-cooling used to reduced weight and simple in construction of engine cylinder block. So,air-cooled engine build heat, the cooling fins permit the wind and air to move the h...

The infection rates of trematode metacercariae were studied in fish from a polishing pond of a wastewater treatment factory and from Bang Yai Canal, Mueang District, Phuket Province, Thailand. The investigation was carried out from April 2001 to April 2002. Nile tilapia (Tilapia nilotica) were collected from the polishing pond, while mullet (Valamugil cunnesius) were collected from Bang Yai Can...

The fish yields of most Nigeria inland waters are generally on the decline for causes that may range from inadequate management of the fisheries to degradation of the water bodies. Sustainable exploitation requires knowledge of the ichthyofaunal composition in the water bodies. We did a survey of fish species in Anambra river basin for 22 months. Fish samples were collected using four different...

Mechanosensation is fundamental to many tetrapod limb functions, yet it remains largely uninvestigated in the paired fins of fishes, limb homologues. Here we examine whether membranous fins may function as passive structures for touch sensation. We investigate the pectoral fins of the pictus catfish (Pimelodus pictus), a species that lives in close association with the benthic substrate and who...

In present study, a 2D rectangular enclosure was considered as latent thermal energy storage (LTES) system. Lauric acid used PCM material. The aim of this study to use fins enhance melting process PCM. Position and shape double were investigating parameters. At first stage three different positions for shape. Results indicated that amongst aforementioned cases, best results achieved when locate...

Pectoral fins are known to play important roles in swimming for many adult fish; however, their functions in fish larvae are unclear. We examined routine pectoral fin movement during rhythmic forward swimming and used genetic ablation to test hypotheses of fin function in larval zebrafish. Fins were active throughout bouts of slow swimming. Initiation was characterized by asymmetric fin abducti...
