Journal Title: International Journal of Aquaculture and Fishery Sciences - Year 2018, Vol 4, Issue 2
Abstract
Koto Panjang Reservoir is the largest reservoir in Riau Province, there are many efforts of floating net cage (KJA) by using feed (pellet) continuously. As a result of many feeds that settle in the bottom of the waters because it is not consumed by the fish. The purpose of this research is to know the pattern of growth circle otolith of kapiek fish that live around KJA and in waters that there is no KJA (natural). The study was conducted from March to September 2016. This study used survey method, with 5 stations, where St1 and St 2 were in waters without KJA, while St3, St4 and St5 were in the waters around KJA. Taking, grinding and observing the growth circle pattern on otolith cucumber fish were conducted based on the Windarti method (2007). The result of the research shows that there is a difference of growth circle pattern on otolith of kapiek fish between the two public waters. Kapiek fish that live freely around KJA does not have dark circles on its otolith, while kapiek fish in waters without KJA have dark circles on its otolith. Thus the presence of food waste from KJA may affect the growth pattern of kapiek fish in Koto Panjang Reservoir shown in the growth circle pattern in its otolith.
