Published: September 2020

Abstract
A parasitology survey on fish groupers was conducted from January to April in 2016 in a Parasitology Laboratory belongs to Fish Quarantine and Inspection Agency, Makassar, to identify parasites from the fish groups. Previous data available at the institute did not distinguish between species of fish examined and the parasites that infect them, most of the fish from different species were only categorized as groupers, while many species of parasites are known to have high host specificity. Fifty-four grouper fish of different species were examined, includes; Cephalopholis sonnerati, C. argus, Plectropomus oligocanthus, P. leopardus, P. areolatus, P. maculatus. The fish species are common groupers that are exported alive to various countries. The fish were sent by exporter companies to the laboratory for disease inspection. The fish species were identified, length and weight were measured, then the whole body surface was visually examined for the presence of large parasites. Operculum was cut, and each gills were removed and placed on a petri dish contained saltwater. Observation of parasites presence was conducted under a stereomicroscope, and identification of parasite to genus level was conducted directly under a compound microscope. Species of parasites found were monogenean; Diplectanum sp., Pseudorhabdosynochus sp., Echinoplectanum leopardi, Echinoplectanum sp., Protozoa; Brooklynella hostilis., Cryptocaryon irritans., Crustacea; Hatschekia sp., Dissonus sp., copepod larvae. Diplectanum sp. was found from P. areolatus and C. sonnerati. The prevalence and mean intensity of the parasite in P. areolatus was 100% and 52.5, respectively, whereas the prevalence and mean intensity of the parasite in C. sonnerati was 50% and 69.6, respectively. Pseudorhabdosynochus sp. was only recorded from Cephalopholis spp. Echinoplectanum leopardi only occurred in P. leopardus. Echinoplectanum sp. was also recorded from P. oligocanthus, P. maculatus and C. sonnerati. Other species of parasites commonly found in the fish examined were B. hostilis., C. irritans, Hatschekia sp. and Dissonus sp. All the parasites are highly pathogenic and may complete their life cycle within a container. Therefore, their occurrence in aquaculture facilities may cause significant damage leading to mortality on fish without proper treatment.

Published: September 2020

Abstract
Mapping of seagrass bed can be done by using different characteristics of satellite images data such as Landsat-8 and Sentinel-2. However, there has been no research compared to the results from those images in Indonesia. This study aims to analyze and compare spatially the condition of seagrass bed from Landsat-8 and Sentinel-2 imagery covered Kodingareng Lompo island. Spatially sharpened (Pan-sharpening) Landsat-8 imagery from 30 to 15 meters resolution in four spectral bands (visible and NIR) were used in this case. The results showed the four classes seagrass cover percentage consisted of sparse class (0 – 25%), medium-class (26 – 50%), dense class (51 – 75%), and very dense class (76 – 100%). Classification of seagrass cover class and water column correction (Depth Invariant Index) value differed between the two imageries. Accuracy test of seagrass cover classification from Landsat-8 (88.1%) and Sentinel-2 (89.2%) were both suitable to use since they were higher than the standard value (>85%). Differences in the characteristics of both images cause differences in the results of the seagrass cover classification.

Abstract
This study aimed to visualize the distribution of yellowfin tuna Thunnus albacores in Bone Gulf, Indonesia. Yellowfin tuna is among the most important large pelagic fish species cached by local fishermen using pole and line gear. This study is a preliminary process in identifying suitable habitat for yellowfin tuna using Sea Surface Temperature (SST) and water depth parameters. It used oceanographic and fishery data from satellite remote sensing of Geographic Information System (GIS). The SST data was gained from Terra/MODIS. The waters depth data was gained from the ETOPO2 satellite database, whereas some points were later confirmed through the Echo sounder record. The experimental fishing was conducted from May to 2019. The result showed that the yellowfin tuna distributions were relatively higher in 30.0 to 31.0 oC SST and 500 to 1,000 m water depth. Both of the parameters analyzed in this study played an important role in the distribution. The numbers represented preferences in defining the optimal habitat of the yellowfin tuna, especially in the study area. This information could be useful to predict the potential fishing zones where yellowfin tuna would be distributed in abundance.

Abstract
In 2014, the project preparation for Coral Reef Management (Coremap) CTI claim that mangrove at Selayar was approximately 676.7 hectares distributed at 15 villages. Tambolongan at Bontosikuyu district was the largest area of about 132 hectares. These values extracted using Landsat imageries based on visual and composite image classification. Since Sentinel 2A launched in 2015, the use of this satellite imagery has spread widely in ecosystem monitoring due to its higher spatial, spectral and temporal resolution and mostly because it is free to access. Nevertheless, field sampling is still needed to crosscheck the final result. Since 2015 three mangrove locations at Selayar island monitored annually. By 2018, two new locations at Pasi island added. In 2019 three sites added at two different islands, so now a total nine mangrove station covering the whole Selayar islands. Nine species of mangroves were found by the end of 2019 monitoring, which are Avicennia alba, A. officinalis, A. marina, Bruguiera gymnorrhiza, Rhizophora apiculata, R. mucronata, R. stylosa, Cerios tagal, and Sonneratia alba. Spectral image characterization by using 12 bands of Sentinel 2A shows that most of these mangroves had peak reflectances at 783 and 865 nanometer, and the highest reflectance are lower than 0.45. These findings may contribute to better spatial identifications for mangrove monitoring and also the consequences to the revision of previous information extracted from Landsat imageries.

Published: September 2020

Abstract
Pekalongan City is one of the cities appointed by the Ministry of Marine Affairs and Fisheries to be developed as a capture fisheries-based minapolitan area. In order to boost production during the Minapolitan Area development, it is required to establish Production Development Activities packages, and one of them is Research and Development Package. Furthermore, to dynamize the flow of knowledge, innovation, and diffusion, and to learn within the framework of the Innovation System, an innovation network is needed. The initial step in developing an innovation network is by mapping and analyzing innovation networks. The purpose of this study is to map and analyze the minapolitan innovation network based on capture fisheries in Pekalongan City. Innovation network analysis is conducted using Social Network Analysis (SNA) method developed by Analytic Technologies Harvard. This SNA method is used to get a general picture of the interaction patterns of actors/institutions/actors that occur in innovation networks. The results of the analysis show that the density value of the capture fisheries-based minapolitan innovation network is 0.15 for the knowledge flow and 0.04 for the business flow. Hence it can be concluded that it is not a complete innovation network (the value of complete network density = 1). The level of connectivity between actors in this innovation network is still small, thus shows the social cohesion or solidarity among actors is still weak.

Abstract
Fishpond farmers in Pinrang Regency, South Sulawesi Province, have adopted Good Aquaculture Practices - GAqP (CBIB in Indonesian), yet the adoption rate of CBIB by traditional fish farmers still fell under the moderate adoption criteria. Therefore, a study aimed at analyzing the correlation between socio-demographic factors and adoption rate in hopes that the adoption of CbBIB can be increased that will have implication for the sustainability of aquaculture besides improving the quantity and quality of products, including food safety. The research method applied was a survey method to obtain primary data collected by structurally distributing questionnaires to respondents. Primary data in the form of socio-demographic characteristics of CBIB adopters and other data, namely the adoption rate of CBIB, were sourced from data reported by Mustafa et al. (2019). To measure the closeness of the relationship between socio-demographic characteristics and adoption rate, a statistical test of Spearman’s Rank correlation coefficient was used. The CBIB adoption rate by fish farmers in Lanrisang and Mattiro Sompe Subdistricts of Pinrang Regency was found to be in the moderate adoption category (adoption rate of 33.34-66.66%). CBIB adopters were all-male, 48.68% aged between 40 and 49 years, 56.58% graduated from high school, 36.84% adopted CBIB less than two years, and 53.95% managed ponds in an area of 1.0-1.9 ha. Moreover, results also showed that five socio-demographic characteristics of CBIB adopters, namely gender, age, education level, length of adoption, and pond area, did not have a significant correlation with the CBIB adoption rate in the ponds of Pinrang Regency. It is recommended to conduct further research by examining other variables of socio-demographic characteristics in addition to the economic aspects of traditional fish farmers to determine their effects on the adoption rate of CBIB.

Abstract
In fact, Karamunting is known to have a high cholesterol content, more specifically, lanosterol based on GCMS test. Lanosterol is the cholesterol that contained in plants, which assumed as a precursor of growth and reproduction hormone for in Crustaceae. This experiment consists of several steps: (1) Karamunting extraction, (2) GCMS test for Karamunting, (3) Making the feed by mixing the ethanol extract Karamunting for four weeks with concentration variable 0 (control), Variable 1: 1: 5, Variable 2: 1:2, Variable 3: 1:1, Variable 4: 2:1 dan Variable 5: 5 : 1. (4) The measured parameters are water quality, growth in weight, growth in length, survival rate (5) Data analysis. Statistical analysis result of weight growth measurement indicates that ethanol extract of Karamunting gives a significant result to the larvae sample (P˂0.05). Statistical analysis result of length growth measurement at the end of the experiment indicates a significant difference between control and each variable (P˂0.05). Statistical analysis result of the survival rate at the end of the experiment indicates that the ethanol extract of Karamunting gives a significant result to the larvae sample (P˂0.05). Based on these results, it can be concluded that the ethanol extract of Karamunting on feed indicated an increase in the molting process the observation in weight and length indicates that the extract can stimulate molting acceleration rate.
