Abstract

The Banggai cardinalfish (Pterapohon kauderni, Koumans 1933),often refered to as BCF, is a restricted range coral reef associated fish endemic to shallow waters (0-5m) arround the Banggai Archipelago, Indonesia. Listed as Endangered un the IUCN Red-List. In 2007 a national BCF Action Plan was developed , and a Distrct MPA was established by decree of the Banggai  Kepulauan District Head, consisting of a network of 10 islands. For 2 of these P. Kauderni conservation in the main management target. We reviewed available phylogenic, genetic and biogeographical data, and examined the MPA network from the viepoint of P. Kauderni genetic diversity conservation. With no pelagic phase and high fidelity, the Banggai cardinalfish population exhibits a level of genetic structure unusual in a marine fish. Several genetically distinct sub populations have been identified. It was concluded that management units should be based  on genetically detrmined sub-populations (stocks). Critical knowledge gaps and several research pririties were identified. In particular , we conclude that a researh programme is necesary for the identification and characterisation of these genetically determined units from biological (including genetic), ecological (e.g. habitat/micro-habitat) and socio-economic (including fishing ground) aspects. We propose to provide management support through the use of the spatial analysis tool MARXAN combined with a GIS database to produce science-based zoning options with management units/targets based on genetic population structure.

Abstract

Microalgae as a source of nutrients, can be a good alternative to the use of high-level organisms. The abundant omega 3 content in plankton, especially phytoplankton, needs to be conducted research on the identification of the types of phytoplankton in milkfish with high omega-3 quality. The purpose of the study was to identify the types of plankton containing omega-3 and to determine the levels of omega-3 from plankton found in milkfish ponds. This research was conducted at the Laboratory of the Faculty of Fisheries and Marine Sciences, Brawijaya University, Malang. The highest abundance of phytoplankton is from the Bachillariophyta division and the lowest division euglenophyta. Five types of plankton were determined to be tested for omega-3 fatty acids using the gas chromatography (GCMS) method, namely: Chaetoceros sp, Tetraselmis sp, Nitzchia, Chlorella and Spirulina. GCMS test results from several types of omega-3 fatty acid plankton isolates in Chaetoceros calcitrans were the highest compared to the other 4 plankton types. Conclusion of the composition of plankton in traditional pond waters consists of 4 phytoplankton divisions namely Chlorophyta, Chrysophyta, Cyanophyta, and Euglenophyta. GCMS test results from several types of plankton isolates omega-3 fatty acids in Chaetoceros sp, the highest compared to Tetraselmis sp, Nitzchia, Chlorella and Spirulina. Suggestion of natural feed in the water of milkfish ponds should use Chaetoceros sp because the content of omega 3 is high. Keywords: phytoplankton, omega-3

Abstract

Industrialisasi menimbulkan efek negatif berupa limbah padat maupun cair yang berpengaruh terhadap lingkungan sekitar.  Jika limbah tersebut dilepaskan ke perairan bebas, akan terjadi perubahan nilai dari perairan itu baik kualitas maupun kuantitas sehingga perairan dapat dianggap tercemar.  Salah satu bahan pencemar pada perairan adalah logam berat Timbal (Pb).  Organisme perairan merupakan kelompok organisme yang pertama kali mengalami dampak secara langsung dari pengaruh limbah atau pencemaran logam berat di perairan.  Salah satu organisme perairan yang menerima dampak langsung pencemaran logam berat adalah tanaman mangrove. Penelitian ini bertujuan mengetahui perbandingan akumulasi logam berat timbal (Pb) pada perairan yang dominan Avicennia marina dan perairan yang sedikit terdapat Avicennia marina di perairan muara sungai Kebon Agung, kecamatan Gunung Anyar, kota Surabaya yang tercemar dan pantai Bama, Taman Nasional Baluran, kabupaten Situbondo yang relatif bersih. Akumulasi logam berat Timbal (Pb) pada sedimen tertinggi terdapat di perairan muara sungai Kebon Agung yaitu sebesar 13,157 ppm, sedangkan akumulasi Pb pada jaringan Avicennia marina tertinggi terdapat pada bagian batang dibandingkan akar, daun dan buah, yaitu sebesar 5,890 ppm.  Berdasarkan nilai Bioconcentration Factor (BCF; perbandingan kandungan logam berat dalam akar atau daun dengan sedimen) dan Translocation Factor (TF; perbandingan logam berat dalam daun dan akar) diketahui bahwa daerah yang dominan Avicennia marina mengakumulasi logam berat Timbal (Pb) lebih banyak dibandingkan daerah yang sedikit terdapat Avicennia marina, tertinggi nilai BCF pada daun, sebesar 0,269 dan 0,302 dan nilai TF sebesar 1,613 dan 1,471.

Abstract

Fitoplankton mempunyai peran sangat penting dalam suatu perairan, selain berada pada dasar rantai makanan sedangkan zooplankton merupakan herbivor pemangsanya. Penelitian mengenai kelimpahan dan keanekaragaman plankton di perairan Selat Bali dilakukan pada musim peralihan II (Nopember 2012) dan musim barat (Pebruari 2013). Penelitian bertujuan untuk mengamati perbedaan kelimpahan dan keanekaragaman plankton pada dua musim angin muson. Sampel air diambil dengan menggunakan water sampler sedangkan sampel plankton diambil secara horisontal dan vertikal  pada kedalaman 1 m dan 20 m dengan jaring plankton Kitahara bermata jaring 20 µm. Hasil pengukuran nutrien pada musim peralihan II memiliki kadar fosfat, nitrat, bahan organik, silikat dan klorofil-a lebih tinggi dibandingkan pada musim barat. Informasi tersebut memperkuat indikasi adanya perpindahan massa air dari lapisan yang lebih dalam ke lapisan yang lebih dangkal. Nutrien fosfat dan nitrat diperlukan untuk mempertahankan fungsi membran sel dan silikia dibutuhkan untuk pembentukan dinding sel terutama pada diatom. Hasil penelitian juga menunjukkan bahwa kelas diatom (Bacillariophyceae) mencapai 95,9 % dari total jenis dan kelimpahan fitoplankton seluruh stasiun penelitian, sisanya berasal dari genus Dinophyceae. Kelimpahan fitoplankton tertinggi terjadi pada musim peralihan II dengan Rhizosolenia stolterfothii sebesar 51.405 sel.L-1 (80,1%), sedangkan pada musim barat copepoda ditemukan melimpah sebesar 8.178 ind.L-1 (88,3 %). Hasil ini mengindikasikan bahwa dengan kelimpahan plankton yang ditemukan perairan Selat Bali dinilai cukup potensial untuk mendukung kehidupan biota laut pelagis. Kata kunci: plankton, selat Bali, rhizosolenia stolterfothii, muson  Abstract Phytoplankton has important role as primary producer in the sea and act as base of food chain while zooplankton act as herbivore prey on them. Research on abundance and diversity of plankton at Bali Strait was performed during transitional season in November 2012 and the west season in February 2013. This research was done to observe the differences in the abundance and diversity of plankton in the two monsoon seasons. Water sample and plankton sample were collected simultaneously at the same location. Water samples were taken using a water sampler, while plankton were taken by using a planktonnet with mesh size 20 μm. Samples were taken vertically and horizontally at a depth of 1 m and 20 m below the surface. The result of nutrient measurement at Bali Strait during transitional II season showed that the concentration of phosphate, nitrate, organic matter, sillica and chlorofill-a are higher than during west season. This result indicates that there is probably movement of water mass from deeper water column to shallower area. Phosphate and nitrate are required by phytoplankton to maintain their cell membrane and sillica are used to form cell wall, especially for diatom. The reasearch also revealed that diatom (Bacillariophyceae) are 95,9 % of total species and abundance of phytoplankton, and the rest are Dinophyceae. It was found that highest abundance occur during transitional season was Rhizosolenia stolterfothii of 51.405 sel.L-1 (80,1 %). While during the west monsoon the Copepod had dominates at 8.178 cell.L-1 (88,3 %). These results indicate that with plankton abundance the Bali Strait has the potential to support pelagic marine life. Keywords: plankton, Bali strait, rhizosolenia stolterfothii, monsoon

Abstract

Sardinella fish (Sardinella lemuru) is a species of important pelagic fish from the family of Clupeidae found in Bali Strait. The dynamic condition of Bali Strait makes it fertile which is identical with plankton blooming. The objective of this research was to understand the potential of saxitoxin in sardinella fish because of dinoflagellates consumption in Bali Strait. The research was conducted in Southeast Monsoon (June - August 2015) and Northwest Monsoon (December 2015 – February 2016). The method used was in situ plankton sampling, counting and ELISA test to determine the level of saxitoxin in the fish. Hydro-oceanographic parameters measured were temperatures, salinity, DO (dissolved oxygen), pH level, phosphate level, nitrate level and transparency. They showed average optimum value for phytoplankton growth especially during Southeast Monsoon which its temperature lower and the nutrients (phosphate nitrate) higher than the Northwest Monsoon. This condition caused high richness of phytoplankton in the water and followed with dinoflagellates richness so they accumulated in sardinella fish. It was supported by the analysis of the fish gastric which showed positive correlation between dinoflagellates richness in the water and the fish gastric. ELISA test also showed that saxitoxin level of fish caught in Southeast Monsoon was higher than the one caught in Northwest Monsoon even though the level of saxitoxin was still in the safe range (less than 80 μg STXeq. per 100 g) but the danger of saxitoxin accumulation should be watched out for.

Abstract

The nutrient content in Banyuwangi coastal environment mostly caused by human activities along the coastal area of Bali strait especially in Banyuwangi surrounding areas. The change of organic element content in waters will directly affect plankton community structure and the aquatic trophic level. The aimed of this research were to analyze the plankton community structure, and to observe the quality of aquatic and determine Bali Strait especially Banyuwangi coastal area trophic level. This research was done in October 2015 at Banyuwangi coastal area. Methods used in this research was descriptive with seawater sampling for water quality analysis of several parameter such as nitrates (NO3), phosphates (PO4), TOM (Total Organic Matter) and Chlorophyll-a, meanwhile other parameters were, temperature, pH, Dissolved Oxygen dan salinity from three different depth of three different stations, coastal area of Bangsring, Tandjung Wangi and Muncar. The results for water quality parameters showed that Bangsring coastal area was the most  healthy waters compared to Bangsring and Muncar. Meanwhile, there were tendency that the concentration mostly high in the surface and decrease along with the deeper depth. This condition presumed caused by the ARLINDO current that passed through Bali strait. Phytoplankton identified and calculated consisted of 3 division, namely Chlorophyta, Chrysophyta, and Cyanophyta with total density ranges between 4-2888 ind/ml. The value of diversity index phytoplankton (H’) ranges between 0,3-0,7. Based on the result it can be concluded that Banyuwangi coastal areas were at throphic level of  oligotrophic tended to mesotrophic in northern part and eutrophic especially in Muncar. Thus, it was suggested for the Government to prevent this area becoming more polluted in the future.
