The aim of the study was to identify vibrio disease in Eucheuma cottonii samples which had the characteristics of ice-ice disease, namely the thallus was whitish and broken. The research was conducted at two locations in Lombok, namely in Ekas Bay and in the waters of Buwun Mas Village. The samples were identified as vibrio bacteria at the Sekotong Marine Aquaculture Center using biochemical methods. The results showed that vibrio bacteria were associated with ice-ice disease in the observed seaweeds. The types of vibrio bacteria that cause ice-ice disease in samples in Ekas Bay and Buwun Mas are Vibrio parahaemolyticus, Vibrio alginolyticus, and Vibrio damsela.

Floating marine debris and litter act as a vector transporting various species across long distances. The present study reports possible transoceanic rafting of a small colony of barnacles on an unopened plastic bottle of Chinese origin found washed ashore on the Ninety Mile Beach in Victoria, Australia. The crustaceans attached were identified to be the goose barnacle Lepas pectinata. Based on the number and size of the colony the marine pollutant was estimated to adrift for several months. We hypothesised the origin of the flotsam, especially the barnacles and how it made its way from the Pacific to be washed ashore in Australia. Furthermore, we identified two types of microbes, Vibrio alginolyticus and Vibrio parahaemolyticus, associated with the Lepas pectinata growing on the bottle. This study appears to be the first report of possible transoceanic rafting on unused plastic pollutants and highlights the potential environmental threats caused by plastic.

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>

Pathogenic Vibrios

Pathogenic vibrios are important etiologic agents in tropical regions and have been frequently recovered from seafoods and aquacultured foods. In this study, commercially frozen seafoods including peeled shrimps and fish and shrimp dumplings were examined. Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio cholerae and Vibria fluvialis were recovered at 36.0%, 15.8%, 14.9% and 13.2%, respectively. A number of psychrotrophic vibrios were selected and their survival in tryptic soy broth (TSB) supplemented with 1% sodium chloride (NaCl) (TSBS medium) and shrimp homogenate at 4°C and −30°C were studied. Two psychrotrophic non-O1 V. cholerae (laboratory stocks no 128 and 129) survived well at these low temperatures. Counts decreased by about 1 log/ml in TSBS medium at 4°C for 6 days and 3 log/ml at −30°C for 3 days. Shrimp homogenate provided better protection than TSBS medium for psychrotrophic V. cholerae at −30°C. Survival of V. cholerae at low temperatures was further increased by the addition of 0.5% of heated pyrophosphate and metaphosphate, probably by decreasing the lethality of the cold injury to the cells. Measures should be taken to minimize the risk from pathogenic vibrios in frozen seafoods, especially if phosphates are used and psychrotrophic strains are present.

Vibrio alginolyticuswas originally classified as biotype 2 ofVibrio parahaemolyticus. Most clinical isolates are recovered from superficial wounds or the external ear infections.V. alginolyticusis acknowledged to be nearly nonpathogenic in humans. The reason for presence ofV. alginolyticus’s virulence is uncertain. We describe a chronic myringitis case in a 47-year-old female due toV. alginolyticus. According to her anamnesis, it was detected that she had sea bathing history in Mugla Coast in Turkey. Pure isolation ofV. alginolyticuswas obtained from external auditory canal’s culture. Investigation and antimicrobial susceptibility of the isolate were performed by the automatized BD Phoenix system and Kirby-Bauer disk diffusion method, respectively. The bacteria were sensitive to all antibiotics. This case was presented to pay attention toVibrio alginolyticusinfections.

Analyze Data

Baguala Bay is a high potential area with a rich fishery resources. Marine aquaculture field area should be determined by considering the ecological, technical, hygienic, socio-economic conditions simultaneously to the laws and regulation. The research is done in order to analyze chemical and biophysical indicators in the waters of Baguala Bay and to determine seaweed (Eucheuma cottonii) cultivation area considering the determination of seaweed cultivation zone. The result is done in February to March 2020 continues by laboratory analysis and data tabulation based on the time schedule. Interpolation Inverse Distance Weighted (IDW) is used to analyze data. The result shows the suitability cultivation area in Baguala Bay is 1048.296 ha or 78.7% is in high suitable rate and 282.483 ha or 21.2% is in suitable rate. Among all of the criteria of suitable cultivation area in Baguala Bay, nitrate is the criteria with the high suitability parameter overall.   ABSTRAK: Teluk Baguala merupakan kawasan yang memiliki potensi sumberdaya perikanan yang cukup melimpah.
