AbstractThe application of biosecurity in seaweed aquaculture plays an important role in reducing the impact of disease and pest outbreaks. The continuous occurrence of seaweed pests including the macroalgal epiphytes, epi-endophytic filamentous algae and biofilms on Kappaphycus farms may also potentially induce further incidences of the ice-ice syndrome. In this study, on-farm biosecurity management measures were tested on the commercially grown seaweeds Kappaphycus malesianus and Kappaphycus alvarezii during peak ice-ice season at Gallam-Gallam Village, Sabah, Malaysia. The investigation was focused on preventative control measures including the early detection of the ice-ice syndrome and pests through propagule health checks, regular cleaning of the crop thallus and associated long-line ropes and monitoring of the environment. Farm procedures and practices were also assessed in terms of their biosecurity ‘risk’ using the hazard analysis and critical control point (HCCAP) approach. Observations were replicated in two different farm management systems; one system adopted routine biosecurity measures and the other had no biosecurity measures. The results showed that the ice-ice syndrome and pest outbreak was significantly decreased by 60–75% for K. malesianus and 29–71% for K. alvarezii at the farm which adopted the routine biosecurity measures compared with the no biosecurity treatment. The biosecurity measures also significantly improved growth rate and seaweed quality. The infection levels of the epi-endophyte Melanothamnus sp. contributed to the ice-ice syndrome in K. malesianus, whilst the epiphyte coverage was correlated to the ice-ice incidence in K. alvarezii. This study provides the first evidence of biosecurity management measures significantly decreasing the incidence of the ice-ice syndrome and pests on a commercial seaweed farm.

<p>Kebijakan pembangunan kemandirian dalam budidaya perikanan dan membangun kemandirian pulau-pulau kecil merupakan kebijakan program Kementerian Kelautan dan Perikanan dalam mendukung poros maritim nasional. Pulau Sebatik di Kabupaten Nunukan memiliki potensi sumberdaya pesisir dan laut cukup besar untuk dikembangkan diantaranya potensi pengembangan budidaya laut, terutama budidaya rumput laut. Penelitian ini bertujuan untuk mengevaluasi kondisi dan langkah-langkah strategis pengembangan budidaya rumput laut di Pulau Sebatik, Kabupaten Nunukan Provinsi Kalimantan Utara. Data dan informasi dikumpulkan melalui media diskusi (Focus Group Discussion/FGD), kunjungan ke lokasi pengembangan budidaya rumput laut, dan data sekunder. Data dianalisis secara deskriptif dengan memberikan opsi-opsi kebijakan pengembangan budidaya rumput laut. Pengembangan budidaya rumput laut di Kabupaten Nunukan cukup berkembang dengan pusat kawasan pengembangannya di Kecamatan Nunukan Selatan. Kappaphycus alvarezii (cottonii) merupakan jenis yang umumnya dibudidayakan dengan metode longline. Dalam tulisan ini, potensi, permasalahan, dan strategi pengembangan budidaya rumput laut yang teridentifikasi di lokasi penelitian dibahas secara komprehensif.</p><p>Policy on aquaculture development in the small and the most outer islands is a strategic program from Ministry of Marine Affair and Fisheries to support national maritime shaft. Sebatik Island in Nunukan Regency has a large potential of coastal and marine resources to be developed include the development of marine aquaculture, especially seaweed culture. This study aimed to evaluate condition and strategic steps in the development of seaweed aquaculture in Sebatik Island, Nunukan Regency North Kalimantan Province. Data and information collected through Focus Group Discussion (FGD), field visit to seaweed aquaculture areas, and secondary data. Data were analyzed descriptively by presenting policy options for seaweed aquaculture development. Marine aquaculture especillay seaweed culture was well developed in Nunukan Regency, which was mainly concentrated in South Nunukan. Kappaphycus alvarezii (cottonii) is the main species cultivated in this region by using long line method. In this paper, the potential, problems and development strategy of seaweed cultivation were identified and discussed comprehensively.</p>
