Abstract

Echinoderms in marine ecology have a role as deposit feeders. This shows the diversity of the Echinoderms phylum found in seagrass ecosystems. Seagrass beds serve as protection and a source of nutrients that maintain the food chain. Tanjung Benoa waters are located in the waters of South Bali which has a seagrass ecosystem. Echinoderms as invertebrate animals can be influenced by abiotic factors, namely salinity and temperature which are affected by the season. This study aims to determine changes in the structure of the Echinodermata community in the western and transitional seasons I in seagrass ecosystems and determine the environmental factors that influence the structure of the Echinoderms community in the waters of Tanjung Benoa. Echinoderms data collection method used is the Underwater Visual Census (UVC) method. Data is taken by using purposive sampling technique. The results showed that in both seasons, the western season and the transitional season I, the phylum of Echinoderms found consisted of 4 classes namely Holothuroidea, Ophiuroidea, Echinoidea and Asteroidea. The diversity index and uniformity of the Ecinodermal phylum found in both seasons shows stable diversity and uniformity. Based on the index of dominance there is one genus that dominates, namely the genus Diadema. Based on the analysis of PCA in the west season, the density of Echinoderms is influenced by phosphate, nitrate, DO, salinity, pH and temperature. Whereas in the transitional season I density is influenced by phosphate, salinity, temperature, nitrate and pH.

Abstract

Mikroalga epifit merupakan organisme yang berperan penting sebagai produsen di lingkungan perairan. Organisme ini hidup menempel selamanya pada suatu substrat sehingga dapat menjadi bioindikator kesehatan lingkungan. Penelitian ini bertujuan mengetahui struktur komunitas mikroalga epifit dan hubungannya dengan parameter lingkungan. Metode substrat buatan digunakan sebagai media tempat menempel mikroalga epifit, yang kemudian dianalisis indeks struktur komunitasnya. Struktur komunitas mikroalga epifit terdiri dari kelimpahan, keanekaragaman, keseragaman dan dominansi, sedangkan parameter perairan diukur yakni suhu, pH, salinitas, total padatan terlarut, nitrat dan fosfat. Hasil penelitian menunjukkan rata-rata kelimpahan mikroalga epifit yakni 112,62 ± 230,25 sel/mm2 dan 50,77 ± 85,34 sel/mm2 berturut-turut pada substrat kasar dan halus. Secara keseluruhan, nilai indeks keanekaragaman mikroalga epifit termasuk dalam kategori sedang, indeks keseragaman kategori tinggi dan indeks dominansi rendah. Salinitas dan fosfat merupakan parameter yang berhubungan signifikan dengan kelimpahan mikroalga epifit. Hasil penelitian mengindikasikan bahwa kondisi perairan di Pulau Serangan masih tergolong bagus bagi pertumbuhan mikroalga epifit.

Abstract

Artificial reef at Jemeluk Bay, Karangasem, Bali is one of the area’s fisheries potential. Artificial reef is an underwater structure that is made for fishes’ protection and feeding ground. The purpose of this research is to know and understand types of reef fishes that surround the artificial reef, as well as the artificial reef’s affect onto the fish’s abundance at Jemeluk Bay. The method used for reef fish monitoring by visual census at artificial reef made from concrete, rubber tire and steel. This research is done towards six coral reef structures to get the reef fishes composition, which is made out of 7 fish families, 17 species, with an abundance total of 708 individuals. The highest fish abundance was founded at the 2nd rubber tire artificial reef with 6,4 individuals/m2, and the lowest fish abundance was found at the 1st concrete artificial reef with 3,28 individuals/m2. From the calculation at six of the artificial reef structures, the diversity index varies between 1,2 – 1,57, which is categorized as low diversity. The diversity value shows that steel artificial reef have the highest fish species diversity, however is still categorized as low.

Abstract

Macrozoobentos are organisms that live at the base of the water (Epifauna) or in the substrate (Infauna) with a size greater than 1 mm. Macrozoobenthos play an important role in the process of decomposition of organic matter in the sediment in the mangrove ecosystem. This research was conducted in August 2018 in the mangrove areas of Serangan Island, Bali. This research has purpose to know the structure of the Macrozoobenthos community in the mangrove ecosystem. It using a purposive sampling method, which consists of 2 stations, located in the north (adjacent TPA Suwung) as station 1 and on the south (directly facing the sea) as station 2. Each station consists of 5 substations with the distance between the substations adjusted to the condition of the existing mangrove community and each substation has 3 plots with a distance between the plot 10 m. The transect is drawn towards the sea for 50 m. The results obtained at station 2 had higher abundance of macrozoobenthos than Station 1, his shows the condition of the substrate at station 2 it supportive for the survival of macrozoobenthos organisms. The difference in the substrate in each station is thought to be one of the factors that influence the difference in macrozoobenthos density. At stations 1 and 2 have medium diversity, high Eveness and low dominance. This shows that the macrozoobenthos community in the mangrove ecosystem in the north and south of Serangan Island is in a stable condition but if the environment experiences a change, the change will affect the structure of the macrozoobenthos community in the ecosystem environment so that the value of species diversity is at a medium level.

Abstract

Cymodoceae serrulata is a type of seagrass that has a slender and round-toothed shape on the tips of leaves that can live in a variety of substrates ranging from rocking to muddy sand. Morphometrics and meristic can describe the environmental conditions of living seagrasses which can be seen from leaf morphology, stem morphology, rhizoma morphology and root morphology. Morfometrics is a measurement to determine the quantitative morphology of an organism while meristic is a calculation of the number of parts of an organism. This research was conducted in January-April 2019 using a purposive sampling method at 8 observation stations in the waters of Sanur and Tanjung Benoa. Data were analyzed by sturges criteria and principal componen analysis. Based on the results of the study, leaf length ranged from 13.4-246.6 mm, leaf width ranged from 3-18.5 mm, stem length ranged from 1-130.3 mm, root length ranged from 10.1-134.1 mm, rhizoma length ranged from 10.1-78.8 mm, rhizoma diameter ranged from 1.2-3.73 mm, the diameter of the leaf stalk ranged from 1.11-3.63 mm and the number of leaves ranged from 2-5 strands. The principal component analysis showed that texture of the substrate (sand, dust, and clay) that most influences the morphometric-meristic seagrass Cymodoceae serrulata is the texture of dust and clay texture. Where the dust texture affects morphometrics-meristik such as the length of the leaf, leaf width, stem length, rhizoma length, root length and number of leaves. While of the stem diameter and rhizoma diameter and root length are influenced by clay texture.

Abstract

The seagrass field in the Sumberkima and Karang Sewu Beach are two of the habitats that support epifauna life. Epifaunas benefit the seagrass field by using it as a habitat, food supply source, and shelter from predators. This research aim to understand the epifauna density in the seagrass ecosystem, its correlation with seagrass density, and their condition in the Sumberkima and Karang Sewu Beach. This research was conducted in January – March 2020, which used the purposive randomize sampling method. Results show that Karang Sewu Beach only has the seagrass Enhalus acoroides, while three species, Enhalus acoroides, Thalassia hemprichii dan Cymodocea rotundata where found in Sumberkima Beach. Epifauna density in Sumberkima range between 933.33 ind/m3 – 2400.00 ind/m3. Meanwhile, epifauna density in Karang Sewu range between 1311.11 ind/m3 – 2544.44 ind/m3. The epifauna that is mostly encountered is Smaragdia rangiana. Correlation analysis result using the Pearson Product Moment shows a positive correlation between epifauna and seagrass density, r = 0.55, which means that there is enough relation between both variables. The epifauna community has a variety value of 1.60 – 2.19 in Sumberkima, and 1.26 – 2.14 in Karang Sewu, which both count as moderate. The uniformity values 0.74 – 0.96 in Sumberkima and 0.65 – 0.85 in Karang Sewu, which both count as high. Dominance value range from 0.14 – 0.28 in Sumberkima and 0.17 – 0.42 in Karang Sewu, which count as low. Overall, the epifauna community is classified as moderate, where if there is a change in the environment, the community will quickly change too.

Abstract

Tongkol fish (Euthynnus sp.) common types of fish resources found in the waters of Bali, especially Karangasem. Fishermen in Seraya Timur Village, Karangasem Regency, use drift gill nets to catch Tuna Fish. The use of drift gill nets is still very simple with the size of the mesh used that is also still diverse, but most use a mesh size of 2 and 2.5 inches. The use of drift gills by fishermen in the village of East Seraya is still very simple and the mesh nets used are also still diverse, but generally use mesh sizes of 2 and 2.5 inches. Therefore, it is necessary to know the level of effectiveness of each of the mesh sizes. The purpose of this study was to determine the amount of tuna fish catch using drift gill nets and the effectiveness of the two mesh sizes in the Seraya Timur waters. This study uses gill drift nets with 2 and 2.5 inch mesh sizes. The number of settings (decrease in net) and haulling (removal of the net) was carried out 22 times in March 2019. The results showed that the total number of catches with a 2 inch mesh size was relatively twice as high as the 2.5 inch mesh. It can be concluded that the net size of 2 inches has a smaller effectiveness compared to 2.5 inch mesh size.

Abstract

Lemuru fishing activity in the Bali Strait is the most dominant fishery sector in that waters. One of the environmental factors that affect lemuru is Sea Surface Temperature (SST) spread seasonally. One Remote Sensing technology that can be used in determining the value of the distribution of SST is Moderate Resolution Imaging Spectroradiometer (MODIS). This study aimed to explore the influence of SST on the production of lemuru fishing (Sardinella lemuru) in the waters of the Bali Strait each seasonally. The method used in this research is descriptive qualitative by look influence between SST seasonally to the production of lemuru fishing at Bali Strait. This study used correlation and regression polynomial equation. The results showed influence of SST seasonally to the production of lemuru fishing in west season amounted to 54.86% (proportional), in east season by 43.88% (inversely), in the transitional seasons I amounted to 37.05% (proportional), and on the intermediate season by 30.64% (proportional). The weak impact of SST on the production of lemuru fishing in the waters of the Bali Strait in every season caused by state of the SST is relatively constant, while the production of fishing lemuru in annually increasing.

Abstract

Thresher sharks are known to have substantial economic value. They are caught globally as target and as bycatch in tuna fisheries. Due to their declining population, they are listed as an appendix II species on CITES, therefore any form of trade and fisheries related to the species have been nationally and internationally regulated. However, information on thresher shark fisheries in Bali is still limited. This study aims to socio-economically characterize thresher shark fishermen in Manggis, Karangasem. The research was conducted in August 2020 – October 2020 by interviewing 53 out of 119 recorded shark fishermen using a structured questionnaire. Shark fishermen use surface longlines to catch thresher sharks (Alopiidae) in between 3 areas, North Nusa Penida-Karangasem, east Nusa Penida and Bangko-Bangko. The fishermen catch sharks exclusively during the months of June-October and catch tuna the rest of the year. Operational costs for 1 boat ranges between Rp 121.000 – Rp 250.000 during 1 round trip. The income generated from shark fishing each trip averages to about Rp 627.714 per boat. Prior to the Covid-19 pandemic, some of the fishermen work jobs in the tourism sector. However, due to the pandemic’s impact on tourism, they have no choice but to be fishermen full time. Although thresher shark fisheries in Manggis are generally small scale, conservation and management strategies need to be implemented to ensure sustainable use of shark resources.
