Gastropods is an important organism that commonly found inhabiting the rocky intertidal area. Distribution pattern of this species is influenced by various factors such as population history, microhabitat, predation and a complex interactions between oceanographic dynamics and ecological features. This study aims to compare the temporal distribution pattern of gastropods at two different rocky intertidal area. This research was conducted at the rocky intertidal area of Amban and Nuni, North Manokwari District, West Papua. Data collection was performed during the daylight and night in April and June 2012 using systematic sampling method. The results showed that both physical and chemical factors are suite for supporting gastropods life. Furthermore, these factors seem to have an impact on gastropod zoning patterns observed in the study area. The similarity index values indicate that the similarity of gastropod species between the two locations is low, which means that the species of gastropods found in each location is quite different. The community structure of gastropod at the study area is stable. In addition, we found that the gastropods diversity were higher during the night than the daylight because gastropods are classified as a nocturnal animals. Key Words: Gastropod; Rocky Intertidal; Community Structure; Nocturnal

Tuna is one of the largest fisheries commodities in Indonesia after shrimp and demersal fish. The genus Thunnus is a type of tuna that dominates the international market. The genus Thunnus consisted of seven species of tuna. In some cases, the same morphological character has caused misidentification and data collection on tuna species. Therefore, this study aimed to identify tuna species that are landed at Benoa Harbor and analyzed their phylogenetic relationships. Species identification and phylogenetic analysed in this study used the mtDNA control region locus. The results of this study indicated that there are five tuna species landed at Benoa Harbor, namely yellowfin tuna (T. albacares), longtail tuna (T. tonggol), bigeye tuna (T. obesus), southern bluefin tuna (T. maccoyii), and albacore tuna (T. alalunga). Based on phylogenetic tree reconstruction, all samples were divided into five according to the number of tuna species resulted from molecular identification. Reconstruction of phylogenetic trees is supported by genetic distance between clades has a value of 0.075 - 0.212, with the closest kinship found in yellowfin tuna (T. albacares) with bigeye tuna (T. obesus) and the farthest found in yelowfin tuna (T. albacares) with albacore tuna (T. alalunga).

The existence of macrozoobenthos in habitats is strongly influenced by physical and chemical conditions of water. One of the macrozoobenthos habitats is seagrass, the amount of seagrass cover and organic matter greatly influences the structure of the macrozoobenthos community. Seagrass in the Sanur Beach area grows on an 8 km stretch of beach stretching from Grand Bali Beach Hotel to Mertasari. In the Sanur Beach area, a lot of research refers to the association of macrozoobenthos in seagrasses and a description of the distribution of mollusca. This study aims to determine the macrozoobenthos community structure. This research was conducted in the Sanur beach area, namely at Segara Ayu Beach and Semawang Beach. In this study macrozoobenthos data collection was carried out by substrate retrieval, and aquatic environmental parameters. The highest species composition at the two stations came from the Cycloneritida sequence, the individual abundance at Segara Ayu beach was higher than Semawang Beach which was 0.024 ind/m3, this was thought to be due to higher seagrass density at Segara Ayu Beach than at Semawang Beach. Diversity index in both stations was classified as medium, high uniformity index, and low dominance index.

High shipping activity in Tanjung Benoa beach has caused a strong possibility of heavy metal contamination to the marine ecosystems. Heavy metal in the water will process a deposition which causes an accumulation to the body of marine biotas especially to the filter feeders such as sea cucumber. This research aims to determine the community structure of sea cucumber and to calculate the bioaccumulation of lead (Pb) content in sea cucumber. Sampling activity was conducted at four sites located in Tanjung Benoa, Bali. At each site, a transect method was performed to assess the community structure of sea cucumber like density, diversity, and species composition. Meanwhile, the analysis of heavy metal was conducted by Atomic Absorption Spectrophotometer. In this research, we found 151 sea cucumbers which is come from five species such as Holothuria scabra, H. edulis, Synapta maculata, H. atra, H. leucospilota. The highest level of density was found in site one (0.0104 ind/m2) and the lowest was found in siten four (0.0034 ind/m2). The highest level diversity index was found in site three (0,37) and the lowest was in site two (0,14). The highest level of uniformity index was found in site three (0,21) and the lowest was in site two (0,01). The highest level of dominance index was found in site two (0,94) and the lowest was site three (0,85). The species composition was dominated by S. maculata which is represents 94.03% of the total species found in Tanjung Benoa. The number of bioaccumulation factor (BCF o-s) showed that the accumulation of Pb is categorized as deconcentrator category or low accumulation level since the number of the bioconcentration factor is less than one. While the number of bioconcentration factor (BCFo-w) is categorized as a low category since the number is less than 100. Therefore, it can be concluded that biota which categorized as a filter feeder such as sea cucumbers, can accumulate heavy metal (Pb) indeed with the low accumulation level

Grouper and seaweed are Indonesian fishery export commodities. One of the regions contributing to the production of groupers and seaweed is the northern waters of Serangan, Bali. However, over the past few years, the production of groupers and seaweed in the northern waters of Serangan has decreased. With these conditions, an effort is needed to increase the production of grouper and seaweed more optimally. One of these efforts is the expansion of area for the development of grouper and seaweed aquaculture in other places, because at present in the northern waters of the attack the condition is not conducive due to the dense sea traffic activities. One place to be used as a place to develop grouper and seaweed aquaculture is the eastern waters of Serangan because it is not too busy with sea traffic activities in the region. To see the potential of the eastern waters of Serangan, it is necessary to study the physical, chemical and biological parameters of these waters. Through the study of these water parameters, it aims to find suitable locations for the development of grouper aquaculture and the development of seaweed cultivation in terms of water quality. The results showed that, in the eastern and northern waters of Serangan, are 60% and 65.21% respectively of the condition of the waters is quite suitable to support the development of grouper aquaculture. Whereas, in the eastern waters of Serangan Island, at the north and central parts, about 64.8% of the condition of the waters is quite appropriate to support the development of seaweed cultivation. Suggestions that can be given through this research is that an economic and socio-cultural review is needed in the eastern waters area of Serangan as a place for developing grouper and seaweed aquaculture.

Sea urchin is one of the biota that inhabiting coral reef and seagrass ecosystems. This spesies is commontly found in hard substrate, especially the substrate in seagrass beds which is a mixture of sand and coral fragments (Aziz, 1994). Sea urchins can be used as indicator organisms for water quality because sea urchins will become one of the first organisms to show signs of pressure (Yulianto, 2010). Serangan Island, geographically located in South Denpasar Subdistrict, Denpasar City, Bali Province which has a sediment in the form of coarse white sand mixed with coral fragments with high water activity. Based on the results of a study on the eastern coast of Serangan, sea urchins consisting of 5 species : D. setosum, E. diadema, E. calamaris, E. mattei, D. palmeri with dominanance species found is D. setosum sea urchins. Densities of sea urchins found in all stations was dominated by D. setosum with a total value sea urchin of 4.3 ind / m2 while the lowest density was in sea urchins of E. calamaris and E. diadema with a total value of 2.5 ind / m2 . Distribution pattern of sea urchins in Pantai Serangan, has a uniform distribution pattern (v < m) and clumped (v > m). D. setosum and E. matthei have uniform distribution with values of 0.29 and 0.21 while E. diadema, E. calamaris and D. palmeri have clustered distribution.

Banggai cardinal fish (Pterapogon kauderni) is a marine fish native to Indonesia. P. kauderni is listed as an endangered species in the red list category by the IUCN. P. kauderni is very dependent on microhabitats in the form of benthic animals (symbionts), namely sea urchins, sea anemones, and hard corals. Besides P. kauderni, other fish from the family Apogonidae also live in association with sea urchins. The purpose of this study was to examine the density of P. kauderni and associated biota and to calculate the density correlation between P. kauderni associated biota in the waters of Gilimanuk Bay, Bali. This study uses a modification of the Belt Transect method, with a transect of 50 meters long and 2.5 meters wide to the left and right. The total density of sea urchins was 0,088 ind/m2, the total density of Fibramia thermalis was 0,021 ind/m2, and the total density of P. kauderni was 0,071 ind/m2. Between P. kauderni and sea urchins there is a correlation with the value of r = 0,711 and a P-value of 0,031 < 0,05 which indicates that the large number of sea urchins will affect the number of P. kauderni in the waters. The correlation between density of P. kauderni and Fibramia thermalis worth r = 0,509 with P-value of 0,160 > 0,05, which means that the number of Fibramia thermalis has no effect on the number of P. kauderni.

The existence of marine debris can be a threat to marine ecosystems. Several studies have shown that marine debris can cause death of marine organisms and a degradation of ecosystems. The West Bali National Park (TNBB) is a conservation area in Bali that is also susceptible to be affected by marine debris pollution, due to its high population and anthropogenic activity in the area. Bali generates about 4.281 tons of waste per day, where 11% of it ends up in the ocean. Therefore, research about marine debris in TNBB is important. The purpose of this research is to find out the characteristics and distribution of stranded marine debris in the TNBB coastal area. This research was conducted in February 2020 at 23 stations by the shoreline. Marine debris data collection was carried out by adapting the method developed by the Commonwealth Scientific and Industrial Research Organization (CSIRO) Global Plastic Pollution Project. Marine debris exists along the coastline with the concentration range between 0.05 – 28.47 items/m2 with the average of 4.29 items/m2. As much as 92.3% of waste were plastic, dominated by three major debris classes, including soft plastic (44.8%), foam (30.8%), and hard plastic (12.4%). Marine debris in the area has various sizes and shapes. As much as 57.9% of debris at TNBB were whole items and the rest of it were fragment items. Marine debris size at TNBB tend to have a big relative size, i.e. between 8-16 cm (32%). Generally, marine debris at TNBB were mostly daily consumer items. Therefore, public awareness play an important role to decrease the amount of marine debris on the TNBB coastal area.
