Abstract

Salinity is one of the environmental factors that influence the body's physiological processes primarily in the osmoregulation process and impacts on growth. The purpose of this study is to see the impact of salinity on osmoregulation and growth and determine the optimum traffic for the maintenance of Panulirus longipes. This research was conducted in September 2019-January 2020, at the Balai Udang Mata Seed City, Kendari City, Southeast Sulawesi, Indonesia. The salinity tested in this study was 28, 31, and 34o/oo.  The results showed that high salinity had an impact on the level of osmotic action obtained, which was higher, but a decrease in the diameter of granulocytes and hyalinocytes was getting smaller. Male lobsters have better adaptability to salinity than females, where the salinity range of 28-34o/oo can still be tolerated by not affecting growth. Conversely, females are strongly affected by salinity and the optimal support for growth is 31o/oo.

Abstract

Aeromonas hydrophila is bacteria that often infect freshwater fish and causes Motile Aeromonas Septicemia (MAS) disease. One alternative antibacterial that can be used is squid ink (Loligo sp.) which contains antibacterial substances. The purpose of this study was to determine the effect of squid ink (Loligo sp.) on antibody titers and bacterial density in tilapia infected with A. hydrophila.This study used a Completely Randomized Design (CRD) with the treatment of squid ink powder in feed at a dose of 52.5 ppm (A), 62.5 ppm (B) and 72.5 ppm (C), positive control (K+) using oxytetracycline ( 20 ppm) on feed and negative control (K-) without giving treatment to feed. The main parameters observed were bacterial density in blood of tilapia (O. niloticus) and antibody titer. In addition to the main parameters, supporting parameters observed in this study included survival rate (SR), and measurements of water quality (temperature, DO and pH).      The best dose in giving squid ink (Loligo sp.) powder in feed was 62.5 ppm (treatment B) because it supresing bacterial density in the blood of tilapia (O. niloticus) until 166.33 X 103 cfu/mL, decreasing antibody titer from 26.67±09.24 % to 13.00±04.62 % and highest survival rate of 90.47%.

Abstract

Tilapia is a superior freshwater commodity in Indonesia. The problem with tilapia farmers is the high price of commercial feed because raw materials are still imported. Alternative materials are needed to reduce the cost of feed. One of the treatments is by substituting local raw materials that can stimulate the growth of tilapia, namely by substituting a combination of earrings spinach flour and bean sprouts in the artificial feed that is useful to spur the growth of cultivated tilapia. This study aims to determine the best dose substitution and effect of earrings spinach flour and waste sprouts flour on artificial feed to the efficiency of feed utilization and growth of tilapia fish (Oreochromis niloticus). The method used is an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 3 repetitions. Test fish used was tilapia with an average weight of 3.37 ± 0.16 grams which were kept in a bucket of 15 L. water. The combination of earrings amaranth flour and bean sprouts flour used was in the ratio of 0%: 0% (A), 100 %: 0% (B), 50%: 50% (C) and 0%: 100% (D). Observation variables included the efficiency of feed utilization, growth, life pass, and water quality. The best results of this study were 50%: 50% (C) with, RGR, EPP, FCR, PER, TKP and Survival, respectively, 76.60 ± 3.07% / day, 76.60 ± 3 , 07%, 1.31 ± 0.05, 2.25 ± 0.04% 91.37 ± 1.45 grams and 86.67 ± 6.67a%. Water quality results in maintenance in the optimal range.
