Pengaruh Perbedaan Suhu terhadap Laju Pertumbuhan Ikan Tambra (Tor Tambra)

Abstract

Effect of temperature on growth rate differences tambra (Tor tambra) has been performed. Tambra (Tor tambra) is one of the fish that have high economic value because of the taste of the meat is tasty and savory. The purpose of this study was to determine the optimal temperature for growth, length and weight relationship of tambra (Tor tambra) at each different temperature. This study used an experimental method with a Completely Randomized Design (CRD) consisting of 4 treatments and 10 replications, treatment A (temperature 23°C), B (temperature 25°C), C (temperature 27°C) and D (temperature 29°C). Results showed that growth at 23°C temperatures better than other temperature treatments. This is because water quality, environmental conditions and feed quality a major impact on the survival of fish. Analysis of a length-weight relationship and condition factor of fish is intended to determine the level of functional correlation between the length of the weight and growth pattern. The analysis showed a correlation between the length of the weight on each observation is very significant (p > 0,05). Growth of tambra in general negative allometric , in other words gain weight more slowly than its length.
