Abstract

ABSTRAK

Salah satu faktor abiotik yang berpengaruh terhadap pertumbuhan dan kelangsungan hidup kepiting bakau adalah suhu. Media suhu yang optimum memberikan dampak pertumbuhan yang maksimum pada kepiting bakau Scylla serrata karena berkaitan dengan proses metabolisme. Penelitian ini bertujuan untuk menguji pengaruh suhu terhadap kelangsungan hidup (SR) dan laju pertumbuhan bobot harian (SGR) kepiting bakau melalui reaksi kondisi fisiologisnya. Penelitian ini terdiri dari perlakuan media bersuhu 25 °C (A), media bersuhu 27 °C (B), media bersuhu 29 °C (C), dan media bersuhu 31 °C (D). Berdasarkan hasil penelitian yang diperoleh suhu 29 °C merupakan suhu terbaik untuk pemeliharaan kepiting bakau dengan sistem resirkulasi, hal ini dapat dilihat dari hasil rasio konversi pakan, pertumbuhan spesifik dan kelangsungan hidup kepiting bakau yang memiliki nilai terbaik dibandingkan perlakuan lainnya. 

 

ABSTRACT

One of the abiotic factors that affects the growth and the survival of mud crabs is temperature. The optimum temperature media will result in increasing of growth rate and survival rate on mud crabs Scylla serrata because it is related to the metabolism process. This study aimed to examine the effect of  temperature on the survival rate (SR) and spesific growth rate (SGR) of mud crab through the reaction of physiological condition. This study consisted of the treatments with the temperature of 25 °C (A), the temperature of 27 °C (B), the temperature of 29 °C (C), dan the temperature of 31 °C (D). Based on the research result obtained 29 °C is the best temperature for the maintenance of mud crab with recirculation system, this can be seen from the result of feed conversion ratio, specific growth and survival of mud crab that have the best than other treatments.
