Abstract

There are a large variety and quite abundant types of small pelagic fish that have high economic value in the Sulawesi Sea. One of which is the blue scad fish or commonly known as malalugis (Decapterus macarellus). This study aims to analyze and determine the status of scad fisheries management and to develop recommendations in the management of scad fisheries in the waters of Sulawesi Sea, North Sulawesi Province. The evaluation of fishery management status is carried out using multi-criteria analysis (MCA) through the development of composite index of each indicator of Ecosystem Approach to Fisheries Management (EAFM). The results showed that, in general, the status of scad fisheries management in North Sulawesi Province, was in ‘good’ category, specifically reviewed from the domain of fish resources fall into the category of “medium”, habitat and ecosystem “good”, fishing techniques “good”, economy “not good”, social “medium” and institutional “good”. Management actions take precedence over domains that have “poor” indicator values. Priority management action is implemented in the economic domain, followed by the domain of fish resources, social, institutional and fishing techniques.Indonesian title: Pengelolaan perikanan ikan layang (Decapterus spp.) di perairan Laut Sulawesi, Provinsi Sulawesi Utara, menggunakan EAFM

Abstract

This study aimed to examine the effect of several types of natural substances in increasing the growth of tilapia optimally. The fish were taken from Board of Fisheries and Freshwater Aquaculture Tatelu (BPBAT), North Sulawesi Province. Fish were acclimatized for a week in ponds in the “mina padi” system, with a density of 25 fish/net. After acclimatization, the fish were fed pellet with the addition of ginger (Zingiber officinale), garlic (Allium sativum Linn), and yeast (Saccharomyces cerevisiae) for 30 days as much as 10% /fish body weight /day with the frequency of feeding twice a day, namely at 08.00 and 16.00. This study used a completely randomized design (CRD) with four treatments, namely treatment A: ginger flour 7.5 g/kg of feed, treatment B: garlic flour 15 g/kg of feed, treatment C: Yeast 5 g/kg of feed and treatment D: commercial feed (control), each had three replications. The weight of fish was scaled weekly. The results showed that the growth of fish fed with the addition of baker’s yeast was better than fish fed with the addition of ginger, garlic, and commercial feed, but statistically the growth of fish fed with baker’s yeast and ginger were not significantly different from each other.

Abstract

This study aimed to find out the right extraction method to produce ketapang leaf extract with best phytochemical content and best inhibition ability against ice-ice causing bacteria. The experiment was conducted at the Laboratory of Fish Health, Environmental and Toxicology, from April to June, 2021. The experiment was designed according to a Completely Randomized Design (CRD) with 5 treatments and 3 replications. The three main treatments were, treatment A: extraction of ketapang leaves Terminalia catappa L. with 95% ethanol (extract A), treatment B: extraction of ketapang leaves T. catappa L. with 40°C water (extract B), and treatment C, extraction of ketapang leaves T. catappa L. with distilled water (extract C).  In the inhibition ability test, each extract obtained from the three main treatments was compared with two controls namely treatment D: positive control (Kanamicyn) and treatment E: negative control (aquadest). The phytochemical content data was analyzed descriptively, while the bacterial inhibition zone diameter data was statistically analyzed with Anova and LSD. The phytochemical analysis result showed that, the extract A contains alkaloids, flavonoids, triterpenoids and tannins,  while extract B and extract C contain alkaloid, saponin and tannin. The inhibition ability test showed that extract A gave the strongest inhibition (14.87 mm) against the ice-ice causing bacteria, and was significantly different from that of extract B (5.23 mm) and C (2.47 mm).  The inhibition ability of extract B was significantly different from that of extract C. The inhibition ability of the three ketapang leaf extracts (A, B and C) against the ice-ice causing bacteria was much weaker and significantly different from that of Kanamicyn (positive control).

Abstract

This study aimed to determine the effect stocking density on growth and determine the effect on the survival of saline tilapia. The experiment was conducted at the Aquaculture Technology Laboratory and the time of the study was from February to August 2021. The experiment was designed according to a completely randomized design (CRD) with 4 treatments and 3 replications so that there were 12 experimental units. The factors tested were differences in stocking density of tilapia with treatment A: 10 fish/20 liters, treatment B: 15 fish/20 liters, treatment C: 20 fish/20 liters, and treatment D: 25 fish/20 liters. Growth data and survival rate (%) were analyzed using analysis of variance for RAL, then LSD test (Least Significance Different) was performed. Observations of water quality include temperature, DO, pH, and salinity. The result of the analysis of variance showed that the difference in stocking density had a significant effect on growth, but on the survival rate had an insignificant effect. The results of the BNT test on growth showed that treatment A was not significantly different from treatments B and C, but treatments A, B, and C were significantly different from treatment D. The temperature range during the experimental period was between 29 0C – 30.9 0C, DO ranged from 4.07 ppm – 6.80 ppm, pH between 6.78 – 7.95, and salinity 25 ppt

Abstract

This research was conducted to examine the effect of different substrates on the growth of Sea Cucumber Holothuria scabra reared in cages in Bahoi Coastal waters. This research was conducted from April to June 2021 in Bahoi Coastal Waters, West Likupang, North Minahasa. The method used in this research is the observation method with three treatments: A (sand), B (mud), C (seagrass), and three replications. The cages are made of nets size 100 cm x 100 cm x 50 cm as many as 9 cages. The sea cucumber size data was collected every two weeks. Samples of sea cucumber were taken randomly from each cage, left for ± 10 minutes, photographed, weighed, then recorded. Data collection for water quality is carried out every week during the day at the lowest tide, between 12:00 to 14:00. Water quality parameters were measured using a thermometer, refractometer, and litmus paper. Based on the research results, the average absolute weight growth and daily growth rate of sea cucumber reared with mud substrate showed the best results, that is 0.55 g and 0.72%, while the sand and seagrass substrates showed negative values. The results of ANOVA (analysis of variance) showed that there was no significant difference between absolute growth and daily growth rate of Sea Cucumber H. scabra reared on sand, mud, and seagrass substrates.

Abstract

High concentrations of chlorophyll-a can be used to predict where fish gather. On the other hand, tropical cyclones are one of the triggering factors for vertical stirring and upwelling that cause fertility of waters. The Sangihe Island area is not an effective area for the formation of tropical cyclones. However, due to its geographical location with a tropical cyclone area and trajectory, the potential for disturbances caused by cyclones is impactful on Sangihe Island. The distribution of wind speed, salinity, sea surface temperature and chlorophyll-a concentration can be detected by satellite remote sensing imagery. This study aims to analyze the impact of Tropical Cyclone Amang on the variability of wind speed, salinity, sea surface temperature and on the concentration of chlorophyll-a in Sangihe Island. This study useswind speed, salinity, sea surface temperature and chlorophyll-a data during the Amang Tropical Cyclone (January 6-27, 2019) from the AQUA-MODIS satellite imagery. The results show that the relationship between wind speed and chlorophyll-a concentration has impact on other parameters where both parameters showed a strong correlation value. It was also showed on the relationship between sea surface temperature and chlorophyll-a.However, the relationship between salinity and chlorophyll-a concentration showed lowest effect among those parameters.Indonesian title: Dampak siklon tropis Amang terhadap variabilitas kecepatan angin, salinitas, suhu permukaan laut, dan hubungannya dengan klorofil-a di perairan laut Pulau Sangihe
