The role of women in the fisheries sector is often neglected, even though women in coastal areas and fishery areas, such as ponds and TPI, almost dominate. The purpose of this study was to analyze the role of fisherwomen in TPI Untia Makassar City in the development of sustainable fisheries. The research was conducted from September to October 2021, in the community of fisherwomen at TPI Untia, Makassar City. The type of data collected in this study is primary data. The method used to collect or obtain data is a survey method with interview techniques. The sampling technique used is the purposive sampling technique. The results of the factor analysis showed that the five variables studied to describe the role of fisherwomen from TPI Untia Makassar City in the development of sustainable fisheries were declared feasible and valid with a correlation value of 0.735. The five variables are divided into 2 factors (components), namely; factor 1, which includes; variable economic role, social role, and domestic role. While factor 2 which includes; participatory and institutional variables.

The mangrove ecosystem in the Sei Carang estuary waters, Tanjungpinang city is a mangrove ecosystem that has land conversion activities and leaves the environment with open land. The purpose of this study was to determine the density and regeneration rate of mangrove ecosystems on post-bauxite mining areas as seen from seedling, sapling, and trees. This research was conducted in July-October 2022. This study was conducted at four stations determined by the purposive sampling method, based on the existence of a mangrove ecosystem in which there are post-bauxite mine openings in the Sei Carang estuary waters, Tanjungpinang City. For each station, 3 plots of data were collected, with a plot size of 1x1m for the seedling category, a plot of 5x5m for sampling and a plot of 10x10m for trees. Data analysis used the formula for species density, for the regeneration rate by comparing the data from the calculation of the density of seedling, sapling and trees and then the formula for the diversity index. The results of the study found eight types of mangroves, namely Rhizophora apiculata, Rhizophora mucronata, Bruguiera gymnorhiza, Soneratia alba, Avicennia lanata, Nypa fruticans, and Lumnitzera litorea. Density values at station 1 for seedling 40,000 individual/Ha, sapling 2,667 individual/Ha, and trees 1,533 individual/Ha, at station 2 for seedling 30,000 individual/Ha, sapling 1,467 individual/Ha, and trees 500 individual/Ha, at station 3 for seedling 36,667 individual/Ha, sapling 5,200 individual/Ha, and trees 1,600 individual/Ha then at station 4 for seedling 53,333 individual/Ha, sapling 3,200 individual/Ha, and trees 2,133 individual/Ha. The level of mangrove regeneration at all observation stations is quite good.

Microplastic contamination in the aquatic environment poses a serious threat to the survival of the ecosystem because it is persistent. This study aims to analyze the concentration of microplastics in the water column in the coastal waters of South Larompong. Sampling was carried out using the volume reduce method with the neuston net at four stations, namely Bonepute Beach, Ponnori Beach, Babana Beach and Damaci Beach. The results showed that there was microplastic contamination and found as many as 386 microplastic particles with an average concentration of 2.68 particles/m3. The results of the analysis of microplastic concentrations showed significant differences (P<0.05) between stations. The highest concentrations of microplastics are found on Bonepute Beach which is an area of aquaculture, fishing and densely populated settlements, then followed by Ponnori Beach which is a tourist area. Meanwhile, the lowest microplastic concentrations are found on Babana Beach, which is the estuary area of the Temboe River and Damaci Beach which is a nearby area. Several forms of microplastics were found, namely granules, fibers, films and fragments which were the most dominant forms. Several colors of microplastics were found, namely blue, brown, green, red, white, and black which were the most dominant colors. There are two types of polymer found, namely HDPE (High Density Polyethylene) and PVA (Polyvinyl alcohol). The conclusion of this study is that the coastal waters of South Larompong have been contaminated with microplastics so that more attention is needed regarding the handling of plastic waste, especially microplastics.

One effort to reduce the role of protein as an energy source in feed is to maximize the use of feed carbohydrates as an energy source and engineering optimization of feed utilization can be done by adding exogenous digestive enzymes to feed. This study aims to determine the level of carbohydrates in the feed after being given cow rumen liquid which gives the best growth response and hepatosomatic index in milkfish. This study was designed using a completely randomized design (CRD) consisting of 4 treatments and 3 replications, Thus, there are 12 experimental units. The treatments were feeding with different levels of carbohydrate feed, namely 27,81; 39,50; 46,97 and 56,75% mixed with 80 mL of rumen liquid per 100 g of feed. Feed was given to juvenile milkfish measuring 7.19±0,036 g which was kept in a recirculating aquarium with a density of 15 fish/45 L of brackish water. The provision of various levels of carbohydrates in the feed had an effect (α<0.05) on relative growth and survival but had no effect (α>0.05) on the hepatosomatic index of milkfish. Statistically, the best relative growth response and survival were found in fish fed with a carbohydrate-level feed treatment of 27,81; 39,50; 46,97%.

Fishing communities in South Sulawesi are known as Punggawa-Sawi. Numerous researches have shown that the partnership between punggawa-sawi is considered as an “exploitation”, judging from its profit-sharing system. Purse seine is a Tuna fishing vessel with 5 to 8 sawi and 1 punggawa. The focus of this study is to explain the fisherman’s preference of performing partnership with the punggawa and the values they implement between the work system. There are 8 groups of purse seine fisherman as the sample with a consideration that there were similarities in the pattern of working relationships and fishing activities. This research used qualitative approach and analyzed by descriptive correlation. The results showed that the recruitment of sawi by the punggawa was based on affinity (25%), experience (12,5%), needs for the ship operation (62,5%). The termination of the applicant can be caused by untruthfulness (50%), illness (12,5%), career change (37,5%). The compensation that is originally accepted by the sawi who quits, will be moved to the afflicted ones. The reasons to become sawi is (1) blood relative (20%), assurance of family economic sustainability (65%), and (3). Difficulty to find another job (15%). The profit-sharing system by the retainer is based on 3 reasons, i.e: (1), retainer investment (55%) (2), high risk (30%) and continuing the existing system (20%). Punggawa-sawi fishing communities have strength in the value of social relations that are built on the basis of shared needs (62.5%) and trust (37.5%). The existence of the punggawa-sawi is because of the social security provided to the retainer’s family (87.5%), both in the form of loans and assistance, and the personality of the retainer (12.5%).

The beating of fishermen due to the Covid-19 pandemic does not necessarily damage the Punggawa-Sawi relationship in Beba, Takalar Regency. The obedience of the Sawi people in choosing to stay with the Punggawa must be photographed from a different angle. This relationship can no longer be seen as a relationship of material interests, such as wages. The reason is, the acquisition of material in their relationship in the midst of the pandemic has also fallen sharply. This study aims to identify Punggawa authority and Sawi compliance that can still exist despite being hit by the Covid-19 pandemic and unfavourable conditions. This study uses a qualitative method with case study analysis. Data sources are divided into two categories, namely primary and secondary sources. Data was collected by using in-depth interviews, observation and documentation techniques. Specifically and tactically, the data analysis technique was carried out following the Miles and Huberman model by reducing data, presenting data and drawing conclusions. The results of this study indicate that the Punggawa authority which is woven into the Punggawa-Sawi relationship in Beba is obtained traditionally. They are not bound by a set of officially announced rules. Sawi's obedience to the retainer was not solely due to material interests. However, their obedience is based more on the characterization of Punggawa because of his generosity and the existence of a familial or kinship relationship between Punggawa and Sawi. This condition makes the relationship between Punggawa and Sawi very close so that it does not waver even in the midst of the Covid-19 pandemic.

Tuna is one of the abundant potentials in North Halmahera Regency, Tobelo. Tuna fish sold in several markets in the city of Tobelo in the form of intact or have been handled, thus tuna fish waste in the form of innards and gills is not utilized, causing a pungent odor at the sales location. The use of fish waste, one of which is an innards fish can be used as an alternative raw material for making fish feed. The raw material for making fish feed must have good nutritional quality including protein sources. This study aims to find out how to process tuna waste into fish feed and the level of respondent's preference for fish feed made. This research was conducted in October - November 2021. The results show that the average panelist assessment of the texture of artificial fish feed texture ranges from 5.45-6.4, the organoleptic value of artificial fish feed ranges from 5.15 to 5.7, the organoleptic value of artificial fish feed ranges from 5.2 to 5.65.

The use of fish waste, one of which is an innards fish can be used as an alternative raw material for making fish feed. The raw material for making fish feed must have good nutritional quality including protein sources. This study aims to find out how to process tuna waste into fish feed and the level of respondent's preference for fish feed made. This research was conducted in October - November 2021. The results show that the average panelist assessment of the texture of artificial fish feed texture ranges from 5.45-6.4, the organoleptic value of artificial fish feed ranges from 5.15 to 5.7, the organoleptic value of artificial fish feed ranges from 5.2 to 5.65.","PeriodicalId":7395,"journal":{"name":"Akuatikisle: Jurnal Akuakultur, Pesisir dan Pulau-Pulau Kecil","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87334653","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 morphometric characteristics of the red crab (Thalamita spinimana) have not been widely studied. This research was conducted from March to May 2021 in the waters of Dompak Tanjungpinang, Riau Islands. Each sample obtained directly measured the morphometric part using a caliper or calipers with an accuracy of 0.05 mm and the crab body weight was also weighed using a digital scale with an accuracy of 0.1 g. The samples obtained during the study were 119 crabs, of which 84 female red crabs and 35 male red crabs. The carapace width range for female crabs is 55.40 – 88.32 mm, while in male crabs the carapace width range is 16.35 and 34 individuals 68.96 – 90.94 mm. The weight of female red crabs is in the range of 50.0 – 103.6 g, while the weight of male crabs is in the range of 49.0 – 142.8 g.

Pollutants in waters that cause DNA damage, such as tributyltin, have been known to cause malformations in the mussel shell, which need attention to be studied. Shell malformations or deformities of blue mussels were observed in Norsminde Fjord harbour. The mean shell thickness index of blue mussels from the polluted site was greater than it from expected clean waters. DNA damages detected using the versatile comet assay which expressed as tail length and olive tail moment were evaluated in blue mussels gill cells both in situ and in vitro. The results showed that the average of DNA damages in treatments, namely the polluted site, tributyltin chloride (TBTC) (10 g/l), and hydrogen peroxide (H2O2) (10 M) were different from the expected unpolluted site. Although comet assay is considered as an unspecific assay, the results proposed the similarity of DNA damage character of blue mussel gill cells when exposed to tributyltin chloride and taken directly from the polluted site. The data obtained are important for assessing the environmental risks created by genotoxic agents, e.g. tributyltin, used as antifouling agents in marine paints.
