Abstract

As an euryhaline fish, milkfish was able to adapt to a wide range of environmental salinity. However, to improve the survival and health of the stressed milkfish, the roles of HSPs are needed to prevent some damages caused by salinity effects. Therefore, maintenance of osmotic homeostasis is very important for milkfish. The present study investigated the HSPs expression induced by hypotonic stress in gills, kidney (osmoregulatory organ) and liver (metabolic organ) of euryhaline milkfish. Since heat shock response is a predominant cellular stress response, two of its major components, heat shock protein 70 (HSP70) and 90 (HSP90) were examined in this study. Two major hsp genes were first identified by cloned from the transcriptome database. In addition, the protein expression were examined through seawater (SW; 35‰) and freshwater (FW) acclimation experiments (> 2 weeks). At the osmoregulatory organ (gill and kidney), the expression of gill HSP90 and 70 revealed upregulation in the FW group. While, kidney HSP90 and 70 was showed no significant different between FW and SW. On the other hand, the expression of HSP90 and 70 based on relative intensities of immunoreactive bands at liver organ was similar between the FW and SW. These findings demonstrated that compared to SW environment, the FW was more stressful to milkfish osmoregulation and effected significantly to osmoregulatory organ.

Abstract

The red tilapia were cultivated in kolong (above 30 years age of lake of post-tin mining) for four month; on the rate of lead (Pb) biomagnification in the organs (liver, kidney and muscle), given positif correlation from planktons in instestine composition, and its effects to the growth rate has been investigated. Results revealed that in the third month, accumulation of lead in the organs of both species were increased, especially in their livers, above the safe level to be consumed (62.14 mg/kg, 8.41 mg/kg and 15.39 mg/kg, 55.23 mg/kg, respectively), but then were decreased in the fourth month. Biomagnification of lead affects the growth rate of both species significantly

Abstract

Teritip (Anomia ephippium) was well known by local people of Bangka Belitung Island as raw material for traditional fermented product called kecalo teritip. The aims of the study were to identify the content of amino acids and fermenting bacterias of the fermented product as a potential functional food. The steps of production process of the fermented product were the collecting of teritip sample from its substrate on the rocks along the beach, separating the whole edible part from the shells of teritip, and then the flesh were washed and salt-fermented. The amino acids of the fermented product were aspartic acid 2,59%, glutamic acid 3,24%, serine 0,55%, histidine 0,43%, glisine 1,69%, threonine 1,36%, arginine 0,96%, alanine 2,1%, tyrosine 0,37%, methionine 0,83%, valine 1,75%, phenilalanine 1,26%, isoleusine 2,15% dan lysine 1,59%. The identification of bacterias showed that there were five main bacterias in the product e.g Serratia marcescens, Acinetobacter baumannii, Actinobacillus sp., Bacillus cereus, dan Pseudomonas putida. High content of amino acids in the fermented product were suitable to be a functional food.

Abstract

Macroalgae or seaweeds is one of the economical nature resources and widespread in coastal waters of Indonesia, especially in coastal waters of Pantai Pasar Lama and Pantai Cukuh, Kaur Regency, Province of Bengkulu. Biodiversities of macroalgae were observed by direct observations and the species of macroalgae that have been found were identified in the observed location. There were three stations of observation, each of them had three lines transect and each line had four quadrat transects. The result showed that in the location of observations, there were 23 species of macroalgae, 10 species of Chlorophyta, 8 species of Rhodophyta and 5 species of Phaeophyta. Station 3 is the highest abundance (3,501.33 g.m-2), followed by station 2 (5,837.33 g.m-2) and the lowest abundance is station 1 (3,501.33 g.m-2). The difference on abundance of the three stations might be caused by the difference of condition of each station.

Abstract

Fish pathogens cause disease in many species of freshwater and marine fish; however, relatively few fish pathogens were known to be zoonotic or causing disease in humans. Zoonotic disease transmission from animals primarily through direct contact, direct contact with vectors and contaminated media, oral ingestion or inhalation of aerosols. Several bacterial pathogens among the potential zoonotic can be found in association with aquatic animals. Aquatic animals live in a wide range of conditions, thereby in fuencing the particular bacterial species that are associated with certain species. Aeromonas spp.; for example, is more commonly associated with freshwater species, whereas Vibrio spp. is generally associated with marine species of aquatic organisms. The most important of the helminths acquired by human from fish were herring worms (Anisakis species) or cod worms (Pseudoterranova decipiens), Diphyllobothrium latum, Paragonimus westermani, liver fluke (Clonorchis sinensis and Opistorchis viverrini), intestinal worms (family Heterophyidae and family Echinostomatidae), Angiostrongylus cantonensis, Spirometra erinacei-europaei (tapeworm) and Gnathostoma spp. (nematodes). All of the parasites mentioned above were associated with social-cultural and behavioural factors, in particular the consumption of raw or undercooked seafood, while the risk to human of contracting infection from fish pathogens was generally low. There were some cases of zoonoses that cause fatal consequences, such as paralysis or even death. Awareness against potential risks is important for fishery managers, anglers, and commercial fishermen.

Abstract

Kegiatan penambangan timah yang illegal dan marak di wilayah Bangka Belitung hingga ke area hutan mangrove dapat mengancam kelestarian dan keanekaragaman hayati, khususnya biota perairan payau (estuarine). Masalah ini perlu mendapat perhatian serius karena area hutan mangrove adalah hunian dan tempat bergantung bagi kehidupan berbagai biota, khususnya biota perairan. Ekosistem mangrove yang sehat menjadi tempat pengasuhan dan penyediaan sumber energi bagi pertumbuhan dan perkembangan biota tersebut. Kerusakan ekosistem mangrove akan berdampak langsung pada penurunan daya dukungnya dalam menopang kehidupan makhluk hidup di dalamnya. Metode pengukuran dari dinamika perubahan daya dukung suatu ekosistem membutuhkan alat berupa indicator. Salah satu indicator penting yang dapat digunakan adalah indicator biologi atau bioindikator. Salah satu kriteria penting untuk menjadi bioindikator adalah makhluk hidup tersebut harus mampu bertahan hidup di dalam rentang perubahan lingkungan yang luas, serta tidak berpindah tempat. Bioindikator digunakan karena hampir seluruh parameter fisika dan kimia perairan di dalam ekosistem mangrove mengalami fluktuasi secara harian. Temilok (Bactronophorus thoracites) adalah kekerangan dari family Teredinidae yang menjadikan batang mangrove (baik yang sudah mati ataupun masih hidup) sebagai bahan makanan pokok sekaligus rumahnya. Jenis kerang pengebor kayu ini sangat layak dijadikan sebagai bioindikator karena selain sebagian besar masa hidupnya dihabiskan hanya di satu tempat, kerang dengan mantel panjang tak terlindung cangkang ini pun mampu bertahan hidup di lingkungan perairan estuarine yang relative tinggi fluktuasi salinitas dan suhunya. Indeks kemontokan atau index of plumpness (K) merupakan indicator bagi kesehatan suatu populasi ikan. Penurunan nilai K dapat menandakan adanya penurunan pada sediaan makanan atau mutu makanan yang merupakan penyokong pertumbuhan jaringan daging atau gonadnya. Sediaan dan mutu makanan temilok berkaitan erat dengan status mutu ekosistem mangrove dalam rentang waktu tertentu. Berdasarkan hal ini maka nilai indeks kemontokan temilok dapat dijadikan ukuran untuk mengetahui perubahan status mutu ekosistem mangrove atau dengan kata lain perubahan daya dukung lingkungan perairan di kawasan hutang mangrove tersebut. Penurunan daya dukung ekosistem mangrove dapat diukur dengan menggunakan bioindikator. Pembuatan database daya dukung ekosistem mangrove dengan pendekatan dinamika indeks kemontokan temilok diharapkan dapat memantau perubahan mutu lingkungan khususnya di ekosistem mangrove. State of the art bagi pengembangan ilmu pengetahuan, khususnya manajemen sumberdaya perairan terletak pada pemanfaatan biota decomposer yang tidak popular sebagai bahan pangan sehingga konflik dalam pemanfaatannya dapat dihindari. Selain itu, dengan keberadaannya di dalam kayu membuat temilok terhindar dari ancaman predasi sehingga meskipun sediaannya tidak banyak namun temilok relatif masih mudah ditemukan

Abstract

The study in predicting quality of water in ex-tin mining lakes in Bangka Island aims to identify the condition of the waters through the measurement of various parameters of waters, formulating models of a possible relationship between various parameters of water at the pit measured and formulate the relationship parameters of pH with other water quality parameters. Sampling conducted research sites in each district / city in Bangka Island with cluster sampling. Measurement of water quality parameters include measurements of pH, dissolved oxygen (DO), temperature, turbidity, and the heavy metals polluted level. The relationship of all the results mathematically analyzed using multiple linear regression as a model of post-tin mining water quality. In the old lakes, obtained fairly linear relationship between temperature parameters pH, DO, and brightness with a correlation coefficient of R = 0.81 and coefficient of determination R2 = 65%. In both types of lakes, relationship model between pH with other parameters is not significant in linearity. Based on test results of heavy metals, some metals were detected in water samples was Pb, Cd and Fe.

Abstract

Wood borer shellfish temilok (Bactronophorus thoracites) is a species of clams from family Teredinidae which used the wood as the main source of their food. The gill of temilok is inhabited by bacterias whom able to use the cellulose rich-fiber of the wood. The finding of bacterias which able to produce a cellulose-degrading enzymes was very usefull to improve the saccharification efficiency and effectivity of cellulose-rich material that comes from crops or papers from offices disposal. The aim of the research was to isolate the bacteria from the gill of temilok, and to know the saccharification kinetics of fiber of pineapple leafs by the secreted cellulase from the bacteria in the form of soluted glucose. Isolated bacterias was growth in a sterilized sea water (salinity of 20o/oo) at 16-20 oC without the addition of nitrogen sources to get the direct atmospheric dinitrogen-using bacteria. The interaction effects of incubation periods (24, 48, and 72 hours), and substrate concentrations (0,2%, 0,4%, and 0,6%) were investigated by measuring and calculating the concentrations of soluted glucose in the media using phenol-sulfate (phesul) method. Experimental design using factorial completed split plot, and data processing using Microsoft Excell. Variance analyses of soluted glucose concentrations showed that the interactions give no significant effects on soluted glucose consentrations in the media. The highest concentration was 88,1722 ppm (incubation period 72 h, substrate concentration 0,2%), and the lowest was 28,8340 ppm (incubation period 48 h, substrate concentration 0,2%).
