Abstract

There are more than 350 species of Chromis fish in the world. Its distribution covers tropical and subtropical water areas. Spesific geographical conditions determine fish development.  This study aims to analyze morphometric meristik, and the differences between chromis fish characters in Indonesia and Korea waters. The research methods were consisted of descriptive methods, Kruskal-Wallis, and Mann Whitney test.The result showed the total length of Abudefduf sexfasciatus found in Palabuhan ratu and Pramuka Island water territories are ranged from 9.9 to 10.2 cm and 7.7 to 13.0 cm.This fish has a dorsal fin, caudal fin which consists of 12-17 weak fingers, and ventral fin consists of 1 hard finger and 4-6 weak fingers. Abudefduf vaigiensis’ found in Palabuhan ratu, Buton Island, Sorong, and Korea water has each ranging total length from 6.0 to 10.6 cm, 10.9 -12.3 cm, 11 cm, and 5.0 to 8.6 cm.The differences are in the caudal and ventral fin. Morphometric characters of Abudefduf sexfasciatus found in Palabuhan ratu and Pramuka Island water territories relatively similar. Morphometric characters of Abudefduf vaigiensis found in Korean waters was not significantly different with Palabuhan ratu, Buton Island, and Sorong water territories. Compared with the other two locations, Abudefduf vaigiensis found the island of Buton water territory has closely related family with the Korean water’s

Abstract

The Red-Blue-Green Light Emitting Diode (RGB-LED) light used in the static lift net can manipulate fish behavior to attract, approach and be concentrated in the lighting area. The purpose of this study is to determine the use of the RGB-LED light intensity with pulse width modulation PWM) value for gathering fish and changing patterns of schooling fish’s movement. Seven treatments with changes in PWM values were the initial conditions, 250, 195, 145, 95 20 and 5 PWM. The methods were by using Hydro-acoustic sonar 360o and ImageJ analysis used to determine the schooling fish’s area in horizontal and vertical by dividing the center zone, main zone, influence zone, and shadow zone. Results of the visualization image of schooling fish as the target fish group visualized by horizontally and vertically. It has the longest duration of 90 ' and 250 PWM has a time duration of 10' shows the difference in the area of schooling fish in four zones. 195, 145 and 95 PWM with each time duration of 10' dominant schooling fish were in the main zone and influence zone, the lowest two light intensities of PWM values were 5 and 20, there are three zones namely center zone, main zone, and shadow zone, schooling fish were increasing with movement pattern by revolving the light source at shadow zone. The approached fish were forming schooling fish because they were attracted to light, with changes in the PWM value that can model the movement patterns of schooling fish.

Abstract

The response of eel fish (Anguilla bicolor) glass eel stadia to different light is fundamental knowledge for developing fishing methods and conserving fish resources. The study aimed to describe how glass eel fish react to different types of light. In the laboratory, glass eels were observed responding to red, blue, and white LED light versus no light as controls. Glass eels ranging in size from 4.0 to 6.1 cm and weighing up to 0.28 g were caught in the Pelabuhanratu estuary of the Cimandiri River. Observations were made for 31 days, beginning five days after the glass eel was captured. The Mann Whitney and Kruskal-Wallis tests were used to describe differences of the glass eel's response to light. Observations showed that glass eels responded more to dark zones with values above 80% when compared to zones given red, blue, and white LED light. The percentage of fish in red LED lights was 23±0.22% higher, with the number of fish on blue LED lights by 10±0.21% and white LED lights 8±0.15% (p<0.05, Kruskal-Wallis). The difference in response to light can be used for glass eel catching applications, especially lamps for eel fish aids and eel conservation to create fishing zones and eels.Keywords: Anguilla bicolor, eel behavior, glass eel, LED light, response to light
