Abstract

Tiger grouper is a type of fish whose habitat is in waters, especially rocky waters with a water depth of about 0.5-3 cm (young) and 7-40 cm (adults) from the surface. Tiger grouper is caught with bottom line and net. The purpose of this study was to determine growth parameters regarding growth patterns and condition factors, and to determine reproductive biology parameters regarding gonads, eggs and ficundity of tiger grouper. This study used a dependent descriptive survey method which was carried out in Labangka waters, Sumbawa Regency. Data analysis used simple regression analysis. The results of data processing showed a positive LWR (length weight relationship) pattern (ln W = -a + b ln L) and a hyper-allometric growth pattern (b>3) with a value of b = 3.6. While the value of the condition factor is K average = 1.41 where the K value obtained indicates that the body of the grouper fish in Labangka is less flat and fleshy and is still in its infancy. The results of fecundity data processing produced 675,073.34 eggs/gonads with a gonad weight of 30 g, a gonad length of 8.8 cm and a parent fish weight of 489 g and a length of 29.8 cm

Abstract

Intention of this research that is to know influence of different temperature to continuity of carp fish life of majalaya (Cyprinus sp) and to know best temperature to continuity of carp fish life of majalaya. Method which is used in this research is method " eksperiment" that is an research method by performing a some unit activity of attempt to see an result of which is gone domicile and affirm relation I come from among variable perceived or investigated. Result of research of gone of is continuity of highest life that is obtained at treatment of B2 (temperature 28oC) mean equal to 88%, followed by treatment of A1 (temperature 26oC) equal to 85%, treatment of C3 (temperature 30oC) equal to 83,33%, and continuity of mean life of down at treatment of D4 (temperature 32oC) that is equal to 81%

Abstract

Koi fish (Cyprinus carpio) is one of the most popular ornamental fish with high economic value and can compete in local and international markets. One of the obstacles in koi fish farming is growth and survival caused by changes in temperature. One of the factors that affect temperature changes is water level. This study aims to determine the effect of water level on the growth and survival of koi fish seeds. This study used an experimental method with a completely randomized design (CRD). There were 4 (four) treatments tested, namely P1 (15 cm) as control, P2 (20 cm), P3 (25 cm), and P4 (30 cm). Each treatment was repeated 3 times, resulting in 12 experimental units. The variables taken were fish length and weight, and water quality (temperature, pH, DO, ammonia). The results showed that. The ideal container water level and can provide the best results to support the growth of koi fish fry is 25 cm. At a water level of 25 cm, weight growth of 0.034 grams/day, length growth of 0.018 cm/day, specific growth rate of 0.021%/day, and survival rate reached 100%. Meanwhile, water quality parameters during the study were in the optimal range, namely temperature 19 - 23 °C, pH 7, dissolved oxygen 5 - 8 mg/L, and ammonia 00.1 - 0.06 mg/L.
