The aimed of this study was to evaluate the capacity of human resources, institutions, and aquaculture marketing systems in the minapolitan area of Merangin Regency. The method of data collection was carried out using a structured interview method with the help of a questionnaire to 493 fish cultivating households (CH). Data were analyzed by multidimensional scaling and leverage analysis using Rapfish software. The results showed that the CH of catfish obtained the highest average index of 55.58, followed by the CH of gouramy at 53.60, the CH of tilapia at 54.57 and the CH of catfish obtained an average index of 54.71. This illustrates that the performance of catfish farmers in aquaculture production technology and management systems is better than the performance of other fish farmers. The results of the evaluation of all aspects of the capacity of human resources, institutions, and aquaculture marketing systems indicate that there are 3 aspects that are in the range of 50.10-75.00 with moderately sustainable status, namely; human resource development aspect with an average index value (AIV) of 68.64, technology aspect with an AIV of 52.98, and natural resources aspect with an AIV of 65.22. Meanwhile, there are 2 aspects that are in the range of 25.10-50.00 with less sustainable status, namely the institutional aspect with an AIV of 48.23 and the economic aspect with an AIV of 48.62.Keywords: Aquaculture; Institutional; Marketing; Sustainability","PeriodicalId":431784,"journal":{"name":"Acta Aquatica: Aquatic Sciences Journal","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114969808","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}

Fish growth performance will reduce when a large amount of energy is redirected for the osmoregulation process. The purpose of this study was to determine the osmotic work level (OWL), osmoregulation pattern, condition factor (K), gonad maturity stages (GMS) and analyze the relationship between OWL with condition factor and GMS of tilapia collected from three floating net cages in Cengklik reservoir, Boyolali. Samples were collected during March – April 2022 followed by some allometric measurements and regression analyses. The OWL of tilapia at the three cages ranged from 4 – 10 mOsm/L H2O; they performed a hyperosmotic osmoregulation pattern. The condition factor of male and female tilapia were1,86±0,21 and 1,89±0,18. GMS of both male and female tilapia was dominated by GMS IV with a fecundity of 9408±2092.54 eggs. OWL did not reveal a significant effect on condition factors or on the GMS of tilapia (p>0.05). Pearson correlation test showed a weak relationship between OWL with condition factors (r = 0,204) and tilapia GMS (r = -0,001). Therefore, tilapia uses less energy in osmotic work to produce good growth performance because it has more energy for growth, as indicated by the high condition factor (K>1) and domination by fish with GMS IV level of mature gonads.Keywords: Condition Factor; Gonad Maturity; Fish Cages; Oreochromis niloticus; Osmoregulation","PeriodicalId":431784,"journal":{"name":"Acta Aquatica: Aquatic Sciences Journal","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128831309","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}

Something that can be done to achieve this goal is to provide the hormone thyroxine in fish feed to increase growth acceleration. This study used an experimental method using a non-factorial completely randomized design (CRD) with five treatments and three replications. The treatments in this study were: thyroxine hormone A (0 mg), B (6 mg), C (7 mg), D (8 mg), and E (9 mg). Parameters observed were: feed efficiency (ep), growth rate, feed conversion ratio (FCR), fish behavior, and survival. The results showed that fish behavior during rearing included fish movement, appetite, and fish skin color. The most active swimming fish were found in all treatments which were given feed containing the hormone thyroxine. The best feed efficiency (EP) value in treatment E was 76.29%. The value of the feed conversion ratio (FCR) in treatment E was 1.76%. The best growth was in treatment E in weight (2.88 cm) and length (36.85 cm). The best survival in treatments C and D was 98%. Water quality parameters during the study were temperature 27-280C, pH 7.0-7.9, Salinity 25-30 ppt, DO 5.9-6.9ppm, and Ammonia 0.0359-0.1946 ppm. The results of the observations showed that there were differences in fish-fed hormone-containing feed for 60 days and fish behavior.

Many tourists who often visit Bangka Jaya beach tourism, therefore it is necessary to analyze the suitability of beach tourism, through this research it will be known the level of tourism suitability to the parameters that have been determined as a determination of the level of security for tourists who carry out beach tourism activities. This study aims to determine the condition of oceanographic parameters for the suitability of Bangka Jaya beach tourism in a beach tourism object and analyze the level of tourism suitability based on the potential of existing resources in the coastal area of Bangka Jaya. Primary data that must be taken in the field include tourism suitability data. The tourism suitability data taken include beach type, beach width, water depth, brightness, current speed, water base material, coastal slope, coastal land cover, hazardous biota, and freshwater availability. Primary data collection was carried out in the morning when the sea water was high and in the afternoon when the sea water was receding. The sampling method in this study used a purposive sampling method in December - January 2022. The method used was descriptive analysis using the Tourism Suitability Index (IKW) analysis. The results of the study of the tourism suitability index (IKW) obtained the results of measuring the parameters of tourism suitability of 90.47% which was a very suitable category (S1). The tourism suitability parameter in the tourism suitability index table (IKW) can be seen that almost every parameter is included in the very suitable category (S1) of all parameters there are two parameters that fall into the appropriate category (S2), namely the beach type parameter and the beach slope parameter.Keywords: Beach; Oceanography; Suitability; Tour","PeriodicalId":431784,"journal":{"name":"Acta Aquatica: Aquatic Sciences Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124100618","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}
