Seagrass had contributed for the life of fish, for instance as a feeding ground, spawning ground, nursery ground, and shelter. Seagrass had a positive correlation against a fish abundance, where diversity and fish abundance were found more associated with seagrass compared on an empty substrate. This research aimed to know the relationship of seagrass density and fish abundance which is important to maintain the long term sustainability of fish in Southern Bali. This research was carried out along Tanjung Benoa and done in four station points started from Tanjung Benoa Beach to Nusa Dua Beach which has characteristic white sandy beaches, big wave beach facing Indian Ocean. Data collection of seagrass used line transect method with 50 x 50 cm2 quadrant and fish sampling used the method of visual censuses in 50 x 5 meters. The analysis of the data used in this study included analysis of seagrass density, fish abundance, linear regression, and statistic test correlation. The results showed the condition of seagrass meadow conditions in Southern Bali that could be categorized very tight. The total range of fish abundance on a 0.18 0.28 – ind/m2 was 10 families of fish, they are Apogonidae, Nemipteridae, Pinguipedidae, Fistularidae, Cepolidae, Labridae, Diodontidae, Pomacentridae, Scorpaenidae, Chaetodontidae, and highest abundance of the family is Apogonidae. A dependent variable (fish abundance) were able to be explained by independent variable (seagrass density) and seagrass density could describe its effects on the fish abundance. The test results of the regression analysis between fish abundance and seagrass density also indicated weak correlation level between the two variables connected.

The availability of coral reefs as habitat is closely related to the exsistence of coral fish resources in the waters. Coral fish resources are very important for tourism, as an object sought after by tourist because of their diverse and charming colors and shapes. Reef fish abundance depends on coral cover. This research was conducted in February 2020. The percentage of coral cover was collected using the Under Water Potography Transect (UPT) method and the visual census method for reef fish communities at five research stations located in the area of the Quick Silver’s pontoon, Toyapakeh, Nusa Penida with area of 20.000 . Based on the results, the diversity index in the first data collection ranged from 3.18-3.76, which means the diversity isin the high category. On the other hand, the diversity index in the second data collections tends to decrease in the range of 2.66-3.40, which means that the diversity is in the medium to high category. The uniformity index for the first and second data collection falls into the category of distressed communities. The dominances index on the two data found inj the low category. From this research, it was also found that the percentage of live coral cover in the area of use of the Quick Silver pontoon ranged from 0.08% to 17.32%, which means that all research stations were classified as bad. These results indicate that the presence of reef fish is not only caused by live corals but also by anthropogenic activities of the pontoon, such as manual feeding by visitors. This condition applies to reef fish with omnivore eating behavior, one of which is the Pomacentridae family of the major fish group. These anthropogenic activities can change the composition of reef fish communities and increase abundance.

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 turtles is one of the marine megafauna which has categorized as protected animal. They are able to migrate long distance along the Indian Ocean, Pacific Ocean and Atlantic Ocean. Heavy metals may enter to marine organism bodies through three ways including, food ingestion, gills, and surface diffusion of the skin. Accumulation of heavy metals in the body for a long time may disrupt the circulatory system, nerves and kidney work. The effort to increase the hatching success is very important for the turtle conservation. Therefore, this study was aims to examined the concentration of heavy metals detected in the eggs of olive ridley (Lepidochelys olivacea) turtle.This study was conducted between July - September 2019 in Serangan Island. The method used in this study was a purposive random sampling, determined by four olive ridley’s nests in their nesting period with each nest of 5 egg samples. The heavy metal contents were analyzed with Atomic Absorption Spectrophotometer. The results showed that Pb concentrations ranged from 5.50-103.66 mg/kg with an average of 36.49 mg/kg, while Cd concentrations ranged from 0.07-16.25 mg/kg with an average of 0.96 mg/kg. The concentrations of heavy metals in sea turtle eggs may come from their parent, which might be already accumulated heavy metals in their tissues. This might occur due to the substances in the eggshell are capable to absorb heavy metals. The results of this study highlight the average concentration of heavy metals in L. olivacea eggs exceeded the threshold of heavy metals for egg products set by the Indonesian Regulation of the Food and Drug Control Agency (BPOM) No. 5 of 2018. This indicates that the eggs of Olive ridley sea turtle in the region are unsafe for human consumption. In addition sea turtle eggs are in high risk for human consumption because they contain heavy metals. All types of turtle products are also protected by UU No. 5 of 1990, therefore the culture of the community in consuming and trading turtle products must be stopped.

Seagrass is also one of the carbon sinks at sea, and as a catcher of sediments that go to sea so seagrass can be used as a balancer of all marine ecosystems. In the seagrass ecosystem, associate various types of marine biota of significant value with a very high level of diversity. Seagrass is affected by environmental conditions and human activities. Serangan island from the 70s already existing tourism that developed there such as Turtle Waching and Dugong Waching. Dugong (Dugong dugon), a plant-eating mammal or herbivore mammal, the main food is seagrass. the existence of a reclamation project on Serangan Island caused many habitats and marine biota around Serangan Island waters to be damaged and lost, especially seagrass plants. This research to determine the seagrass survival rate if transplanted in the North Serangan waters region and to determine the growth rate of Rhizoma seagrass with Species Thallasia hemprichii , Cymodocea rotundata, Halodule ununervis, and Halophila ovalis transplanted in the waters of North Serangan. This research was conducted in the month of February - April 2018. The research consisted of two stations with one station in a dense region of human activity and the station 2 without any human activity. Seagrass transplantation is done by using frame made of iron with size 1x1 meter. The results showed that at station 1 the level of seagrass survival was lower than station 2, it was caused by the dense human activity at station 1. So was the rate of growth at station 1 lower than station 2. This could also be due to the water quality which is lower at station 1.

Studies over the past decade have shown that microplastics are widespread in marine environments, at sea level, on coastlines, and the seabed. Microplastic sources come from small particles used in the cosmetic industry and plastic industry base materials. Other microplastic sources emerge through the degradation of larger pieces of plastic in the environment due to physical and chemical processes, caused by light, heat, oxygen, water, and organisms. Microplastics tend to be digestible by marine organisms and potentially transferred to higher trophic organisms through the food chain, and thus toxic pollutants will potentially harm marine organisms and even humans through bioaccumulation and biomagnification. This research was conducted to determine the characteristics of microplastics that pollute marine fish consumption that is landed in Bali. Samples were gathered from traditional fishermen who landed their catch in Bali. Microplastic is identified in the digestive tract of fish. The samples of fish obtained by Decapterus spp (Selayang), Auxis Rochei (tongkol), Rastrelliger spp (kembung), and Sardinella lemuru (Lemuru). 39 fish out of the total identified 89 fish were found to be contaminated with 69 microplastics (fiber, fragments, film) and 1 mesoplastic (fragment). The size of the plastic found is between 0.32 to 22 mm. The abundance of microplastics in fish caught in Bali's waters is 0.78 (SD 1.15) particles/fish. The finding of microplastics in the digestive tract of fish caught by traditional fishermen in Bali is feared to have the potential to harm marine organisms and even humans through the process of bioaccumulation and biomagnification.

Kawasan ekosistem mangrove Desa Pejarakan merupakan kawasan yang sedang diusulkan sebagai kawasan konservasi oleh kelompok masyarakat NCF Putri Menjangan, Kecamatan Gerokgak. Hal ini membuat diversitas biota laut salah satunya makrozoobentos dapat berkembang biak dengan baik. Selain itu, adanya vegetasi mangrove dan perbedaan substrat juga mempengaruhi diversitas makrozoobentos. Pada penelitian ini digunakan metode purpossive sampling untuk menentukan lokasi pengambilan sampel mangrove yang diasumsikan dengan adanya perbedaan substrat di setiap stasiunnya seluas 10 x 10 M, dalam transek tersebut dilakukan pengambilan sampel makrozoobentos dengan transek 1 X 1 m. Perbedaan substrat ini mempengaruhi nilai diversitas yang didapatkan, pada nilai komposisi jenis yang didapatkan untuk vegetasi mangrove tertinggi terdapat di stasiun 3 pada genus Sonneratia sebesar 62%. Sedangkan untuk nilai kepadatan dan diversitas mangrove tertinggi terdapat di stasiun 2 dengan nilai kepadatan 0,09 ind/m2 dan nilai diversitas sebesar 0,937. Lain halnya dengan nilai kepadatan dan diversitas tertinggi untuk makrozoobentos terjadi pada stasiun 1 dengan nilai kepadatan makrozoobentos sebesar 25,50 ind/m2, sedangkan untuk nilai diversitas makrozoobentos sebesar 2,865. Oleh karena itu, kategori diversitas untuk mangrove termasuk kategori diversitas rendah berbanding terbalik dengan keseluruhan nilai diversitas makrozoobentos yang termasuk dalam berbagai kategori diversitas sedang. Oleh karena itu, kondisi ini diasumsikan bahwa dengan adanya perbedaan substrat yang terjadi pada stasiun 1 berupa pasir berlempung, stasiun 2 berupa lempung berdebu dan stasiun 3 berupa lempung ini, dapat mempengaruhi perbedaan jenis yang terdapat di setiap stasiun. Hal ini dikarenakanan setiap makrozoobentos memiliki toleransi hidupnya masing-masing untuk menyesuaikan diri dengan habitatnya.

The growth of the industrial sector in many countries which is relatively fast can increase emissions from greenhouse gases (GHGs) such as carbon dioxide (CO2) in the atmosphere. One of the aspects in reducing carbon gas is by maintaining forests and oceans to store carbon. One of the marine resources that is quite potential as storing CO2 gas is sea grass beds. Sea grass has a major role, namely as a carbon sink in the ocean or known as the Blue Carbon and is used for photosynthesis. The purpose of this study was to determine the carbon stocks in sea grasses at the top of the substrate (leaves), the bottom of the substrate (roots and rhizome) and on each type of sea grass obtained at Karang Sewu Beach. Determination of sampling points is as many as 6 stations and for sea grass sampling was carried out by purposive random sampling, referring to the density of sea grass which is assumed to represent or describe the condition of these waters. This research applied the dry ashing method that was carried out by crushing the sample components at 500?C. The results showed carbon deposits on the top of the substrate (leaves) of 0.01 tons, and on the bottom of the substrate (rhizomes and roots) of 0.02 tons. The yield of carbon stocks at the bottom of the substrate was higher than the top of the substrate due to the presence of organic matter, which is stored on the substrate into a carbon absorption factor at the bottom of the sea grass under the substrate.
