Abstract

Narrow-barred Spanish mackerel (Scomberomorus commerson) is an exportable fish captured by gillnet fishing fleets from Bintan Regency. The fleets are operated in the Riau Archipelago waters but information on their activities is limited. Such information is important to the institution the Agency for Marine and Fisheries Affairs of Archipelagic Riau Province for ensuring the sustainability of the fisheries from both economic and biological perspectives. This study aims to determine the spatial-temporal distributions of the mackerel fishing grounds along the year with reference to the capture data, sea surface temperatures, chlorophyll-a concentrations, and salinities in the last 4 months of 2022. This study analyzed data from a fish export company, the PSDKP office at Tanjungpinang, Bintan, interviews of fishers affiliated with 44 fishing boat samples, and satellite-based marine data. Analysis on the monthly fishing productivity and optimum marine conditions for the mackerels were carried out to determine prospects of five recognized fishing grounds. Besides Lingga Islands, the fishing grounds are highly prospective from August to November. The longest fishing seasons are expected around Bangka Island (11 months). The spatial and temporal patterns show that the north-south-north shifts in fishing grounds that are associated with regional climates, i.e., monsoon winds.

Abstract

Narrow-barred Spanish mackerel (Scomberomorus commerson) is one of the high-value commercial fish species exported from the Riau Archipelago. To meet export standards, this species must fulfill specific quality criteria to be considered suitable for export. This study aims to analyze the fishing season pattern and size structure of catchable Spanish mackerel (Scomberomorus commerson) in the waters of the Riau Archipelago. Data were collected through field surveys, direct observation of catches, and analysis of gillnet vessel logbook records from 2018 to 2022. Fishing productivity was calculated using catch per unit effort (CPUE), and the seasonal pattern was identified using the Simple Moving Average (SMA) method and monthly fishing season index (Mt,b). The results showed that the fishing season for Spanish mackerel occurs from January to May, with the peak season in February. The size structure analysis revealed that 87.6% of the sampled fish were larger than 61 cm, indicating that they had reached first maturity (catchable size). Nevertheless, a portion of smaller fish was still caught, highlighting the need for improved management of fishing gear and fishing grounds to support resource sustainability. These findings, once implemented, are expected to significantly improve the sustainability of Spanish mackerel populations, offering hope for the future of this species. These findings are expected to contribute to the implementation of precision fisheries management in Fisheries Management Area (FMA) 711. Key words: catchable size, catch per uni effort, fishing season pattern, precision fisheries, Spanish mackerel

Abstract

The management of laboratory assets at the Faculty of Marine and Fisheries Science (FIKP) is still carried out manually using physical documents and Microsoft Excel, which is prone to recording errors, data duplication, and reporting delays. This study aims to develop an integrated web-based laboratory equipment inventory and rental information system. The development method uses the Agile Development approach with stages including requirements, design, development, testing, deployment, and review, with testing conducted using Blackbox Testing. The system was built using PHP with the Laravel framework and MySQL database. Testing results on 19 test scenarios across six main modules (login, equipment management, borrowing, returning, reporting, and user management) showed a 100% success rate with all functions operating as expected. This system integrates inventory, borrowing, rental, payment, and reporting features into a single digital platform, thereby improving efficiency, transparency, and accountability in laboratory asset management
