Abstract

The fisheries sector provided a significant contribution to the Indonesian economy by increasing export activities in every year. The exported fisheries product are categorized of live fish, frozen fish, preservation products from various types of fish, crustaceans, and molluscs. The contamination of pathogenic bacteria Vibrio parahaemolyticus and Escherichia coli causing healthy problems originating from the fishery sector (sea-food borne disease). These two bacteria contaminated fisheries product is due to mishandling and storaging in the processing, which causes acute diarrhea, gastrointestinal infections and fever. The multiplex polymerase chain reaction (mPCR) method was developed to increase the efficiency of time, effort and accuracy of the bacterial contamination testing process. The mPCR method begins with the optimization of the two bacterial gene targets, sensitivity test, specificity test and then applied to samples of fishery products. The mPCR method is carried out in two mechanisms, namely “one-run” conducted from bacterial colonies isolated on agar media and “one-tube” which is applied directly from fishery products. The results of the development of the mPCR method on V. parahaemolyticus and E. coli resulted in sensitivity at concentrations of DNA 5.6 pg/ml and DNA 5.5 pg/ml, respectively. One-tube mPCR application obtained 7 positive colonies of V. parahaemolyticus and 38 positive colonies of E. coli. Meanwhile, one-tube mPCR which was applied directly from shrimp samples could identify the two bacteria.

Abstract

Indonesia become a maritime country with large of ocean area and beach line with marine species diversity reaches 37% of the world’s fish. This makes Indonesia have aquaculture potential that supported by an appropriate climate. However, the challenge of viral diseases caused by Infectious Spleen and Kidney Necrosis Virus (ISKNV) and Viral Nervous Necrosis (VNN) would hamper marine aquaculture and causing huge economic losses. Therefore, it is necessary to carry out early detection methods that are efficient, fast, precise and accurate to identifying these viral disease. Here we developed a multiplex-PCR (mPCR) a method that can detect simultaneously of the ISKNV and VNN. The results of this method showed high sensitivity and specificity by using MCP and CP gene target primers to detect ISKNV and VNN, respectively. From a total of 353 samples of seawater fish examined by mPCR, positive results following of single infection of ISKNV and VNN were 14 and 2, respectively. We also found that 18 grouper fish was co-infection with these viruses. From these results, it shows that the mPCR method developed has efficiency, faster and high accuracy. This founding was possible to be applied in laboratory testing or early detection system in the field for ISKNV and VNN.

Abstract

Karang lunak mempunyai tekstur kerangka yang lunak berupa duri-duri kecil dari kalsium karbonat yang ada dalam jaringan tubuhnya. Pada umumnya karang lunak melekat pada substrat yang keras di dasar perairan. Penelitian ini bertujuan untuk mengetahui tingkat kelangsungan hidup, laju pertumbuhan relatif dan mutlak, dan perbandingan laju pertumbuhan karang lunak pada salinitas yang berbeda. Salinitas merupakan kadar garam terlarut pada air laut. Salinitas berperan penting untuk mendukung kehidupan biota laut termasuk karang lunak. Penelitian dilakukan di Laboratorium Ilmu Kelautan dari tgl 27 Januari 2019 sampai 09 Mei 2019 dengan cara mengukur panjang dan lebar fragmen karang hasil transplantasi yang di tempelkan di setiap akuarium dengan salinitas yang berbeda. Tingkat kelangsungan hidup yang didapatkan pada akuarium dengan salinitas 28, 31, dan 34 yaitu 100 % sedangkan untuk akuarium dengn salinitas 36 yaitu 40% karang lunak dapat hidup sampai akhir penelitian. Laju pertumbuhan karang lunak relatif bervariasi karena pengaruh lingkungan dan kualitas air. Sedangkan laju pertumbuhan mutlak panjang selama 3 bulan mendapatkan nilai yaitu Akuarium Salinitas 28 sebesar 3,221 cm/minggu dan 1,382 cm/minggu; Akuarium salinitas 31 sebesar 3,285 cm/minggu dan 1,433 cm/minggu; Akuarium salinitas 34 sebesar 1,753 cm/minggu dan 0,713 cm/minggu; dan Akuarium salinitas 36 sebesar 0,359 cm/minggu dan 0,224 cm/minggu. Ada perbedaan yang nyata pada laju pertumbuhan karang lunak Cladiella sp. pada salinitas yang berbeda..  Kata Kunci: Karang Lunak, Cladiella sp., Salinitas, Laju Pertumbuhan, Pertumbuhan

Abstract

AbstractIn fish catching activity, the fishermen in Banyuanyar district use mini tools for catching fish (purse seine) and use light assist tools for an operation in the night day. The light, that is used, is kerosene pressure lantern and mercury lights or lamp that is used on water surface (surface lamp). This kind of light is used to collect "pelagic” fish that has positive phototaxis characteristic. Puffer fish's response towards different sourse of light, that's kerosene pressure lantern and mercury light is needed to be known. Therefore, we can know the source of light that is more effective in order to collect the fish. It is hoped that the productivity of puffer fish will be developed for the fishermen. During the research with ten times repeating, the total account of puffer fish's haul that is resulted with two different treatment  by using kerosene pressure lantern and mercury light is that 810 kg and 1.460 kg. The data of puffer fish's haul that is gotten after using MannWhitney test shows that the kerosene pressure lantern and mercury light not to really different, especially in the haul of puffer fish in significant standart (0,05) is 2,262, while in Mann-Whitney test account is 0,171. That means the fishermans in Banyuanyar can use kerosene pressure lantern and mercury light for catching fish as the light assist tools for an operation in the night day.

Abstract

HighlightsCoral cover, rugosity, and reef fish abundance was determinedThe relationship between coral cover and rugosity and fish abundance was analyzed.Coral cover in East Java were categorized as medium – good.The rugosity index and the fish abundance were highest in Bangsring Waters.There are no relationships between coral cover and fish abundance, but there is relationship between rugosity and fish abundance.AbstractA coral reef is one of the most complex and specific ecosystems in a tropical area. It is identified by its high productivity and biodiversity. This research aims to discover the percentage of coral reef cover and rugosity, as well as the fish abundance in several locations in East Java, Indonesia. In addition, this research aims to investigate the correlation of coral reef cover and rugosity with the density of coral reef fish. This research was conducted in three locations, i.e., Bangsring Waters of Wongsorejo District, Banyuwangi Regency; Gili Noko Bawean Island, Gresik Regency; and Kramat Island, Gili Genting District, Sumenep Regency. This research employed the Line Intercept Transect (LIT) method to calculate the percentage of coral reef cover, the Chain Intercept Transect (CIT) method to determine the coral reef rugosity, and the Belt Transect method to estimate the fish abundance. From this research, it was revealed that the highest coral reef cover was in Bawean waters, while the highest rugosity was in Bangring waters. In addition, the highest coral reef fish density was in Bangsring waters. Meanwhile, the coral reef fish density did not correlate with the percentage of coral reef cover. In contrast, it correlated with the coral reef rugosity.
