“…10,19,20 Pollution, overfishing and wetland conversion may potentially threaten to this species. 21 Numerous studies on A. testudineus have been dedicated to describe, for example: food and feeding habits, [22][23][24] reproductive biology, 8,25 boldness, 26 growth performance and survival rate, 27,28 length-weight relationship and condition factor, 29,30 morphometric and meristic variation, 31 water quality assessment, 20 phototactic responses, 32,33 conservation and aquaculture, 34 and fishing activity, [35][36][37] as well as overview of business prospect for this species. 38,39 It is generally accepted that the length-weight relationship is the most common scientific approach that used for analyzing growth pattern of an individual fish species 40 and advanced techniques for morphometric analysis was recently presented .…”

This study provides scientific evidence on the length-weight relationship, condition factor and growth patterns of the Climbing perch (Anabas testudineus) from Sungai Batang River, Indonesia. The fish were obtained from local fishermen. A total of 156 individuals of A. testudineus consisted of 77 males and 79 females (55-125mm total length and 3-47g weight) were analyzed using SPSS-16 software. There were no statistically significance differences in the total length (TL), body depth (BD), and body weight (W) between male and female, as well as the W/TL and BD/TL ratio values of the fish (P>0.05). Most of total catch falls within the range of 80 and 89mm total length and more than 40% of total catch weighed between 10 and 19g. The W/TL ratio value of A. testudineus in the present study was more or less identical to that of A. testudineus from other different geographical areas. The fish samples were in good condition and grew negatively allometric (b=2.7766-2.8791). Outcomes of this study could be useful for fisheries management and conservation measures in this river.

“…This result decreased by 5.67% compared to 2017 and increased by 0.18% compared to 2020. Catches in Indonesian waters are very diverse, with types of fishing gear in the form of using fish aggregating devices (FADs) and lights [5], [28]- [32]. The use of lights as fishing aids is used to lure fish to congregate.…”

<span lang="EN-US">The utilization of fishing gear has been growing until now. One of these tools is an underwater fishing light that has been used by fishermen. However, until now this device still works conventionally and only provides one color. Based on these problems and the rapid development of the internet of things (IoT), an underwater fishing light was created and designed that can work with the IoT system and provide various colors of light according to the needs of fishermen. The design of this tool uses several tools and materials, such as generators, power adapters, controller modules, generators, and the Magic Home Pro application. This tool operates at 12 V DC and consumes 144 W of electric power. Utilization of this tool can also indirectly reduce the consumption of electrical and fuel energy on board and support the blue economy. The results of testing the device show that the IoT system can work well, provide light colors according to orders, is waterproof, and provides a fairly good light intensity with an average of 6.89 Lux (0-8 Lux).</span>

Phototaxis in climbing perch (Anabas testudineus) was investigated by subjecting fish to LED light traps (blue, green, yellow, orange, red, white) and control (total 13 traps). The trap was constructed of polyamide (PA) nylon monofilament (31.75 mm mesh size), fastened around two wire ring frames (∅ 490 mm) with a net height of 270 mm. A lamp was placed on the bottom of the trap. 96 individuals, consisting of 34 males and 62 females, were analysed. Both continuous and blinking light traps were considerably higher in the number of catch compared to the control. The body size of catch ranged from 76-135 mm TL and 8.00-55.00 g W. The mean YPUEs (yield per unit effort) for male and female were 4.00 ± 2.25 and 7.00 ± 4.50 g trap−1 trial-1, respectively. The CPUEs (catch per unit effort) for continuous, blinking light traps and the control ranged from 0.43 to 0.93, 0.21 to 0.86, and 0.21 fish trap−1night−1, respectively. The mean condition factor (K) values of 2.10 ± 0.40 for males and 2.13 ± 0.34 for females indicate fish with better condition. Positive group responses of fish were more pronounced in the middle size classes between 90 and 109 mm TL. Negative allometric growth pattern (b) (1.7271-1.8828) was observed, indicating that the culture system should be refined. A. testudineus showed positive phototaxis to the “colors of light”. In addition, efforts to collect climbing perch from the wild for breeding and commercial purposes may benefit from this study.
