Preliminary Test of Fish Respiratory and Locomotive Signal Using Multispecies Freshwater Bio indicator (MFB)

摘要: Fish produces many types of behavior as response to stress that cause by pollution. Respiration and locomotion are two main responses normally produced. As such, study on these is important especially for pollution monitoring. Study fish respiratory locomotive behaviors was undertaken using multispecies freshwater bio indicator (MFB). Signal produced determines the specific frequency range activities. This aims produce unstressed signals (ventilation locomotion) a respond TSS contamination. Three common species namely guppy (Poecilia reticulata), fighthing (Trichopsis vitatus) Malaysian masher (Tor tambroides) were used test conducted 24-hour period. Result indicates ventilation activities clearly separated different wavelength all but each similar activity. A paired t-test confirmed activity from not differ significantly (p > 0.05, α = 0.05). Only significant load percentage signal increase concentration increase. Similar observed species. demonstrates contamination can be detected at early stage maximum into river system could estimated.
