Indonesia is the second-largest contributor of plastic debris in the world. The abundance of plastic debris and the bioavailability of its fragmented form known as Microplastics (MPs; < 5 mm of size) can be dangerous for marine environments. This study investigates the presence of MPs in the sea water and marine organisms (Placuna placenta) at Tambak Lorok Waters located at the coast of Semarang city, Central Java, Indonesia. All of the microplastics collected from both samples were identified by their shape, color, size (using Olympus Stereo Microscope), and polymer type (using Fourier Transform Infra-Red Spectroscopy/FTIR). The study found that the Microplastic concentration in the water samples had an average of 12.6 particles.L-1, where the color and size distribution were predominantly blue colored fragments sized less than 50 µm. Examination of the study area showed that microplastics concentration in P. placenta was 1 item and 0.033 items.g-1 for each of the organism. Whereas for physical aspects of microplastics found in the oysters showed the blue colored fibers with range size 300-1000 µm were mostly present. Majority of the polymer types of microplastics found in this study were low-density polyethylene, nylon, polystyrene, and polypropylene. Data from this study shows that microplastics were present in the Tambak Lorok coastal waters. However, there was no significant statistical correlation between the concentration of microplastics in the seawater and the P. placenta, the presence of microplastics in the seawater were found to be ingested by the P. placenta.

Recently, expanded consideration has been paid to the business and potentiality of microalgae. Some microalgae are at present being studied for their capacity to find important metabolites for the drug industry or aquacultural applications. Concerning these biotechnological challenges, there is a consistent exertion accommodated in both finding and taking advantage of new microalgal assets and fostering their putative business results or modern valorizations. The crude methanol extracts of three microalgae, Dunaliella salina, Tetraselmis chuii, and Isochrysis galbana, have been investigated for antibacterial activity using the disk diffusion method against aquatic pathogens of fish, shrimp, and shellfish e.g. Pseudomonas fluorescence and Vibrio harveyi. This research aimed to analyze the antibacterial activity of crude extract of these microalgae against aquatic pathogens. The disk diffusion method was used to investigate the antibacterial activity. The result showed that only T. chuii has the inhibition zone for both tested bacteria P. fluorescence and V. harveyi with the inhibition zone of 3.0 ± 0.6 mm on 100 µg. g–1 of extract concentration and 4.20 ± 1.1 mm against P. fluorescence on 10000 µg. g–1 of extract concentration. While D. salina and I. galbana have inhibition zone only for V. harveyi with the inhibition zone of 4.4 ± 0.6 mm and 3.2 ± 0.7 mm on 10000 µg. g–1 of extract concentration. These three microalgae may have potential use in aquatic pathogens as antimicrobial agents. It would be possible to develop biologically active compounds of microalgae as a functional feed for aquaculture.

Marine algae known as one producers of bioactive compounds. This study aims to analyze the cytotoxicity and antiviral activity in Sargassum polycystum and Sargassum ilicifolium tested with Herpes Simplex Virus (HSV). The polysaccharides extract of algae was used in this study, as sulfated polysaccharides have been reported has bioactivity. Cytotoxicity either antiviral could be correlated with the sulfate content as well as nature and chemical composition of the polysaccharides. Cytotoxicity and antiviral analysis based upon cell viability. Using the Vero cell / HSV-1 model, cytotoxicity was evaluated by incubating cellular suspensions (3.5×105 cells.mL-1) with various dilutions (concentration from 1 to 500 µg.mL-1, four wells per concentration) of fractions in 96-well plates (72h, 37°C, 5% CO2) in Eagle's MEM containing 8% FCS. The cells were examined daily under a phase-contrast microscope to determine the minimum concentration of hydrolysate dry matter that induced alterations in cell morphology, including swelling, shrinkage, granularity and detachment. Algae S. illicifolium was found to have the highest cytotoxic content in each solution compared to S. polycystum. Algae S. illicifolium in KOH 4M (cellulose) reached 2,707 µg.ml-1, then HCl pH 2 (fucoidan) was 2,477 µg.ml-1, then CaCl2 2% (fucoidan) was 2,362 µg.ml-1, and in Na2CO3 3% (alginates) was 2,134 µg.ml-1. For antiviral, S. polycystum contained the highest antiviral compounds compared to S. illicifolium with KOH 4M (cellulose) solution was reached 67.02 µg.ml-1. Then in Na2CO3 3% (alginates) which was 33.25 µg.ml-1, then CaCl2 2% (fucoidan) which was 31.62 µg.ml-1,and HCl pH 2 (fucoidan) was 30.08 µg.ml-1. After all, the highest bioactivity compounds was found with KOH 4M (cellulose) for cytotoxicity in S. ilicifolium and antiviral activity in S. polycystum.

Problem of metabolite transfers from intestine to gonadal acini by way of macrophagous haemocytes was investigated in scallop Pecten maximus. A 1 ml of 4 mg/ml solution of Cadmium-free ferritin (Sigma) was injected into the lumen of the proximal extremity of descending portion of the intestine. Two types of experiments were carried out, in vivo and in vitro. For the first, observation by light and electron microscopy was showed that ferritin was detected in the lumen and between the microvilli. In the intestinal cells, ferritin was observed in the vacuoles and lysosomal type. Under basement lamina, it is noted the presence of ferritin on underlying connective tissue, macrophagous haemocytes and near the gonadal acini male and female. The in vitro experiments gave the same results. Based on these results. it is concluded that intestine play a role in the nutrition for gametogenesis and that the metabolite transfer is by way of macrophagous haemocytes.

Blood cockle Anadara granosa is a popular sea food in Indonesia and potential for aquaculture. Currently, blood cockle aquaculture is at early stage, done by taking the larva from wild and raised them in the pond. Wild animal naturally carries parasites without outward clinical signs but can cause disease problem under aquaculture condition. This study aimed to identify parasites and histopathology changes in wild A. granosa. Blood cockles (n=90) were randomly collected during 3 months at three stations in the coastal waters of Bedono (Station 1: the intertidal area of the edge near to the mangrove area, station 2: the center of intertidal area, station 3: the area near to the sea), a village located on North Java coast and supplied blood cockle larva to the area. Parasites examination was conducted in the laboratory by macroscopic (observation of clinical symptoms) for ectoparasites and microscopic (using a microscope) for endoparasites. Histopathology preparation was done by taking three cockles at each station and cutting tissue that includes gills, foot, gonads, digestive tract and mantle. Organs were fixed in a 10% NBF solution, processed, mounted in paraffin and stained with hematoxylin and eosin. Parasites found were identified and the level of intensity and prevalence were calculated. There were three species of parasites found: Pinnotheres sp. (Intensity 1 ind/cockle; Prevalence: 3.33%), Perkinsus sp. (Intensity: 9.3 cell/cockle; Prevalence: 37.03%), Nematopsis sp. (Intensity: 4.25 cell/cockle; Prevalence: 29.62%). There were no histopathology changes on infected tissues which may relate to low diversity, prevalence and intensity of parasites found in this study.

Betahwalang has been one of the main contributors to the Blue Swimming Crab (BSC, Portunus pelagicus) fisheries production in Central Java Province. Recruitment of the BSC depends to a large extend on the abundance of crab larvae. However, information on larval distribution of the crab affecting the recruitment to the fishery, fishery management and decision making to support crab conservation in Betahwalang area has been lacking. The purpose of this study is to describe the spatial and temporal distribution of BSC larvae in the crab conservation area, to identify the larval stage most commonly occurs in the conservation area, and to develop process of decision making to managing conservation areas. This study was conducted in twelve months, starting from January until December 2018. The spatial distribution of the crab larvae was analyzed and mapped by means of SPSS and ArcGIS. The results of this study indicate that the crab larvae occur in the conservation area throughout the year. The highest larval abundance of the crab occurs in May, September, and November. The most commonly found crab larval stages were megalopa. As megalopa and crablet stages are relatively much more active and closer to the adult form, their occurrence in the conservation area and throughout the year of 2018 suggests the existence of continuous support to the Blue Swimming Crab recruitment for the following year. The spatial and temporal distribution of the larvae were influenced by oceanographic parameters including temperature, nitrate and phosphate, which were associated with monsoonal changes in the Java Sea.
