Halophila ovalis and Thalassia hemprichii are seagrass species have the potential to become an agent of phytoremediation by determining the concentration of heavy metals Pb and Cd that have accumulated in them. This study was conducted in January 2018 in Southern Serangan Beach. The purpose of investigating the concentration of heavy metals in water, sediments, roots and leaves of seagrass and determine the bioaccumulation, translocation character and can be made as an agent for phytoremediation. The method used is purposive random sampling method, determined by 3 point. The point is determined from the condition closest to the port Benoa to the outermost point the bay mouth. Determination of station points is considering the presence of the most seagrasses. Results obtained in this study obtained average Pb concentration in water 0.0521 ppm, average metal Cd 0.1652 ppm, the average sediment Pb 75.8574 ppm, Cd 15.33593 ppm, concentration of Pb and Cd in roots and leaves of H. ovalis and T. hemprichii respectively Pb 42.4940 ppm, 45.5334 ppm, and 35.6207 ppm, 38.3931 ppm.

However, the quality of lemuru fish is decrease due to the presence of plastic waste that flow into the Bali Strait. Plastic is a material that’s difficult to decompose, but by using oxidation or mechanical processes causing plastic break to micrometer. Microplastic will be more easily eaten and have a direct impact on the food chain and cause morphological damage or chemical effects that carried by plastic. Based on these problems, its important to conduct research on spatial and temporal microplastic movements in the Bali Strait.

It is feared will lead to overfishing which eventually led to a drastic reduction in fish stocks in nature. So that people will be faced with the problem of scarcity of fish resources. One of the fish landing sites in Bali is Pangkalan Pendaratan Ikan (PPI) Kedonganan located in Fishery Management Area of Republic Indonesia (WPP-RI) 713. Therefore, it is necessary to understanding the current status of fish resources is very important in order to be a strong foundation in the management fisheries in PPI Kedonganan. The study was conducted by assessing five indicators of fish resources (fish size, yuwana fish, species composition, range collapse, and ETP species) by establishing a set of criteria, scores and weights and analyzed by multi-criteria analysis (MCA) approach. There found 16 species of catch fish with Cob Fish as dominant catch fish (54%).

An average of 99% of fish catched were the target fish (Indicator of species composition). An average of 28.33% of fish catches included yuwana fish (Indicator of yuwana fish proportion). The results of interviews, it was found that 73% of fishermen state that fishing areas increasingly difficult from year to year (Indicator ranges collapse). There were <20% of fish catches including protected species (Scomberomorus commerson and Sphyrna lewini). It is also supported based on fisherman interview data that there were still protected fish such as turtles, sharks and rays that are caught but in small quantities (Indicator of ETP fish species).

The aims of this study to determine the temporal of composition species and fluctuations of plankton abundance temporally in the waters of the Lombok Strait. The study was conducted in the Lombok Strait in November 2017. Data was collected at one point and sample was only take on the surface of the waters. The genus composition of the most widely found phytoplankton Bacillariophyceae class (19 genera) and from the widely obtained zooplankton Hexanauplia class (7 genera). The highest abundance of phytoplankton occurs during high tide during afternoon. This phenomenon is caused by photosynthesis of phytoplankton in the water surface. In contrast to the abundance of the highest zooplankton occurs during high tide in the early morning. This is caused by zooplankton's daily vertical migration and negative phototaxis. Comparison of phytoplankton abundance with zooplankton abundance is inversely proportional, zooplankton abundance depends on abundance of phytoplankton, because phytoplankton grow faster by cell substraction, compared to phototaxis of in zooplankton. It is also a predation of phytoplankton by zooplankton.","PeriodicalId":30849,"journal":{"name":"Journal of Marine and Aquatic Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44632283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purposes of this research are to examine the Lead concentration in the surface waters and plankton, and to determine lead bioaccumulation in plankton in the Benoa Bay. The samplings were conducted on May 2018. Lead concentration in the waters and plankton were analized using Inductively Coupled Plasma Emission (ICPE) with wet destruction method. The result shows that Benoa Bay is heavily contaminated by Lead. According to the Decree of the Minister Environment No. 51 of 2004 about Sea Water Quality Standards, concentration of lead in sea waters is <0.008 mg/L. Concentration of lead in Benoa Bay water surface is 0.001 to 0.053 mg/L and in plankton is 0.001 to 9.287 mg/Kg. It is found that the bioconcentration factor (BCF) of plankton is 593.45.

The results showed that the fish with the highest ISC value was Amatitlania nigrofasciata, while the fish with the lowest ISC (Index of Stomach Content) value was Xiphophorus hellerii var. 1. The standard deviation range of almost all fish species is close to zero, so it is suspected that the contents of the stomach are nearly similiar.

Based on the analysis of the contents of the stomach content, Oreochromis niloticus, Osteochilus vittatus, and Xiphophorus hellerii var. 2 are belonging to herbivorous fish. While Amatitlania nigrofasciata, Cyprinus carpio, Xiphophorus hellerii var. 1, and Rasbora lateristriata are belonging to omnivorous fish, which are tending to herbivores.
