The living marine aquarium trade has been known to mediate various aquatic invaders to spread and established a new population outside of their natural home range. In most cases, the introduce species cause a cascaded effect which harm the native species and their ecosystem. The successful of the invasion event often related to the genetic properties of the introduced species. Therefore, using a molecular approach based on a mitochondrial DNA marker, the present work aimed to evaluate the population genetic structure of the introduced P. kauderni population in Bali Strait. Samples were collected from four sites in Gilimanuk Bay, Bali Strait. Our results showed a high haplotype diversity and low nucleotide diversity that might be a signal of a bottleneck. Overall, we found five haplotypes comprising two unique haplotypes and three shared haplotypes. Genetic structure was detected in some localities, which indicates Pterapogon kauderni might originated from various genetically distinct populations. However, we could not conclusively determine the observed patterns of the genetic structure within each site. These patterns are likely related to the multiple introduction event of P. kauderni in Bali Strait. Additional samples from both side (introduced and native habitat) combined with more rapidly evolving markers may describe the structure more clearly.

This research is conducted to find out the genetic profiles of Kayuan clan which is belong to Pasek Catur Sanak Bali Mula, indigenous Balinese people. The DNA profiles is identified by using Microsatellite DNA of Y chromosome. Genes or DNA in Y chromosome are descended from father to son (patrilinealism). Four loci of microsatellite DNA from Y chromosome are used, including DYS19, DYS390, DYS393 and DYS395 to amplified DNA samples from 67 males probands. The probands are people of Kayuan clan from Siakin, Songan, Blandingan and Kutuh villages, Kintamani sub district and others are originally from Jehem village, Tembuku sub district, Bangli regency. The research found 12 allele varieties from all the analyzed loci, which resulted in low genetic diversity (0.33 + 0.001). There are 4 combinations alleles of 4 loci that created12 various haplotypes, the greatest one is haplotype 1 (0.39), followed by haplotype 2 (0.16), haplotype 7 (0,12) and the smallest one is haplotype 6 (0,10). On the other hand, eight other alleles found on the smaller frequencies. Two similar allele combinations were also found on DNA profiles of Celagi clan, which is also belong to the similar family, Pasek Catur Sanak Bali Mula. The two allele are haplotype 6 and 5 found in both, Pasek Kayuan and Pasek Celagi. The haplotype 6 as dominant allele of Celagi clan by adoption, haplotype 5 however, the frequency was the lowest. This allele only detected in one member of each clan due to mutation.

Seaweed is a low level plant that can not be distinguished between the roots, stems and leaves so-called thallus. In seaweed cultivation process, seaweed farmers use monoculture system. But with the growing knowledge there is a more profitable system that is with the co-culture system. The co-culture system is a cultivation system that combines species from different trophic levels in the same system and considers environmental sustainability. The existence of co-culture system is believed to help fishermen in increasing income and overcome environmental problems due to the results of cultivation activities that are not utilized. This research was conducted for 42 days on May 2, 2018 - June 13, 2018 in the waters of Coast Geger, Nusa Dua, Bali. The method used is the RAL method (Completely Randomized Design) using three treatments and three replications. The monoculture cultivation system as a control and co-culture cultivation system with different density of abalone is 20 and 40 abalone consists of 10 seeds of seaweed with the same initial weight of 100 grams. The results showed that the highest seaweed-specific growth rate between the monoculture system and the co-culture system in cycles 1 and 2 was found in the co-culture system, whereas in cycle 3 the co-culture system experienced lower growth rate due to competition between thallus, the epiphytes attached to the cultivation net of co-culture, large enough current, and the loss of abalone that allegedly taken by the community around the coast. In this study there is also a tip of the thallus that is susceptible to ice-ice disease due to the presence of fish predators.

Bali Strait is a waters region with the greatest potential for catching pelagic fish, one of which is lemuru (Sardinella lemuru). The quality of lemuru fish is thought to decrease due to the presence of plastic waste entering from the watershed and empties into the Bali Strait. The plastic waste will floating in the water column, which causes the plastic to be torn apart or degraded by sunlight and form plastic particles called microplastic. The size of microplastic that similar to phytoplankton and zooplankton allow lemuru to accidentally ingest the microplastic. The purpose of this study was to analyze the type of microplastic and calculate microplastic abundance in the digestive tract of lemuru fish (Sardinella lemuru) caught in the Bali Strait. This research was conducted from May to July 2018. Sampling was done by collecting fish landed at the Kedonganan Fish Landing Port. Sample analysis was carried out at the Laboratory of Marine Science, Faculty of Marine Science and Fisheries, Udayana University. The most common type of microplastic contained in the digestive tract of lemuru fish is fiber, which comes from synthetic materials in clothing and also fishing gear such as fishing rods or nets. Microplastic abundance in the digestive tract of lemuru protolan in this study was 1 particle/fish.

Pandawa Beach is a famous tourist destination among locals and foreigners, located in Kutuh village, Kuta Selatan sub district, Badung regency, Bali. Tourism activities can create various negative impacts on the surrounding environment because increased human interference in ecologically areas, the massive development of tourism has affected balance of nature ecosystem in an area, especially the carrying capacity. Carrying capacity is a concept developed for natural resources and environmental management to prevent the occurrence of environmental disturbance or destruction. The researches about carrying capacity it so necessary to find out, has suitable or non suitable carrying capacity, especially at Pandawa beach on the high season at the beginning year (January-early March 2019). The method used in this research was conducted with field observations for primary data collection with the method of interviews to tourists, while the secondary data was obtained from shore managers and literature studies. The data required was wide of the area, the time required enjoyed based on activities type. The result found that wide of area (Lt) required for tourism in high season was 95.09 , time required for tourist activities (Wp) was 2.08 hours. The carrying capacity of Pandawa beach is 9.907 people/day or 307.111 people/month, 3.685.327 people/year which is classified as under carrying capacity. With a carrying capacity of 9.907 people/day, it would be very good if the utilization of the carrying capacity of only about 5.000 people/ day. When the high season conditions in 2019 the number of tourists visiting Pandawa Beach is still in a reasonable condition or classified as under carrying capacity.

Abalon is one of the marine commodities that have high economic value to foreign countries. The abandoning market demand for abalons causes a decline in abalone populations in nature due to exploitation. To meet market needs without affecting the abalone population in nature, cultivation is carried out. Success in the cultivation of abalone one of them is determined by the control of feed. This study aims to determine the effect of different types of feed on the growth of Haliotis squamata abalone. Types of food that can be used as abalone foods are Euchema cottonii and Gracilaria sp. with a feeding percentage of 20% of the abalone weight. This study was conducted for 45 days at Geger Beach, Nusa Dua, Bali using a completely randomized design method consisting of three treatments and three replications. The results showed that the highest value of the specific growth rate was in the T3 treatment using Gracilaria sp. the value is 0.25%, then followed by T1 treatment which uses Euchema cottonii feed with a value of 0.07%, while the lowest is in T2 treatment using combination feed Euchema cottonii and Gracilaria sp. whose value is 0.01%. The highest survival rate in T3 treatment using Gracilaria sp. value was 68%, followed by niali on T2 treatment using combination feed Euchema cottonii and Gracilaria sp. that is 58%, and the lowest in T1 treatment using Euchema cottonii feed the value is 43%. Water quality parameters including temperature, salinity, DO, pH, nitrate flow velocity, and phosphate do not reach the quality standards for biota.

Tuna is one of the main catching commodities in the waters of Southeast Karangasem. Fishers in the Southeast waters of Karangasem used drift gillnet operations to find pelagic fish such as mackerel. This study aims to determine the composition of fish catches using different net sizes and determine the effect of different gill nets on the catch of tuna fish in the southeast waters of the Karangasem Regency. The study was conducted for one month from mid-October to mid-November 2017 by following fishers' fishing trips. The fishing gear used was gill nets with differences, namely 2' 2.5 and 3 inches. The data was taken directly by operating the gill net, which has three different mesh sizes then the data was analyzed by ANOVA. Based on the research found four types of fish, namely Tuna (Euthynnus sp.), ikan kembung (Restrelliger kanagurta), barracuda (Sphyraena barracuda), and Manta sp. with details on 2.5 sized nets, three species (cobs, mackerel, barracuda), while sediment nets with a size of 2 (tuna and mackerel), and 3 (tuna and manta rays). Each gets two types of fish. Based on the ANOVA test, the calculated F results in this study are (7.7608) and F table (3.4668). The difference in the size of the gill nets significantly affects the catch of tongkol fish. The F test value shows that the F count was greater than the F table.

Vegetation Indices is one of the remote sensing parameters that can be used to estimate the mangrove forest density. The purpose of this study is to determine the vegetation index with the best accuracy to estimate the condition of mangrove density, as well as determine the spatial distribution of mangrove density in the TNBB area. This study uses Sentinel-2A satellite imagery data and five different vegetation indices, namely NDVI, NNIR, EVI, mRE-SR, and vegetation index developed in this study. The method of determining samples in the field uses stratified random and proportional sampling. Data collection of canopy density used hemispherical photography method, which is taking vertical photos with a 180o angle of view using a camera with a Fish Eye or Wide lens. Data analysis used in this study is regression analysis, coefficient of determination test, model validation test, and paired t test. From statistical tests conducted on several vegetation indices, the mRE-SR vegetation index value shows the best results on all the accuracy parameters tested. The R2 value was generated by the mRE-SR vegetation index from the relationship between mangrove density results from field measurements with the vegetation index value and the estimated density results shows that the highest values, namely 0.909 and 0.935. These results show that the mRE-SR vegetation index is the best vegetation index in explaining the variation of mangrove density in the field. The mRE-SR vegetation index also has the lowest deviation of the estimated value, with the resulting SE values in the two linear relationships of 1,592 and 0,999. In addition, the mRE-SR vegetation index has a P (T <= t) two-tail value greater than the significance level (0.05), the results means that two values of the tested variables are not significant different. The calculation results show that the total area of mangroves in TNBB is 409.21 ha. From the percentage of density obtained, the mangrove density class was only distributed in the medium and solid density classes.
