Indonesian Journal of Coastal and Marine StudiesIndonesian Journal of Coastal and Marine StudiesSquid is a popular marine fishery commodity, leading to increased demand and substantial domestic production. This study aims to determine the composition, size distribution, and productivity of catches using different attractor colors. Sampling was conducted in the Makassar Strait with 12 repetitions of three attractor treatments. This quantitative research employed a capture experiment method, with data analyzed descriptively based on attractor color. Results showed that the catch composition consisted of 149 fish: 16.11% caught with white attractors, 32.21% with black attractors, and 51.68% with blue attractors. Weight distribution revealed the highest results with blue attractors (15-95 g, 46.62 ± 21.93 g), while length distribution showed the highest results with black attractors (7.5-20 cm, 10.33 ± 2.34 cm). The squid caught were predominantly medium-sized.
The study concluded that the composition of squid catches varied significantly with attractor color, with blue attractors yielding the highest proportion of catches.Weight distribution differed across colors, with blue attractors resulting in the heaviest squid, while black attractors yielded the longest squid.The productivity of squid fishing was highest with blue attractors, indicating their superior effectiveness in attracting squid.
Further research should investigate the optimal placement depth and spacing of attractors to maximize their effectiveness in attracting squid, considering the specific bathymetry and current patterns of the Makassar Strait. Additionally, studies could explore the long-term impact of attractor use on squid population dynamics and the broader marine ecosystem, including potential effects on other species and habitat structure. Finally, research is needed to assess the economic viability of implementing attractor technology on a larger scale, considering the costs of construction, maintenance, and potential benefits to local fishing communities, and to determine the most cost-effective and sustainable materials for attractor construction, balancing durability with environmental impact. These investigations will contribute to a more comprehensive understanding of attractor technology and its potential for sustainable fisheries management in the region.
