Asian Journal Of Aquatic Sciences is a journal publishes scientific articles from research by lecturers and other researchers in the waters sector. Focusing on aspects of aquatic ecology for the use of this habitat as an ecosystem for producing food (fisheries and agriculture) and its function for the earth's ecosystem. Covers aspects of biology, physics and chemistry, both for freshwater (rivers, lakes, swamps, reservoirs), brackish waters (mangrove swamps, river estuaries) and marine waters (coastal and offshore seas).

Abstract

Tuna (Thunnus sp.) is the second largest foreign exchange earner after shrimp. One type of tuna which is an export commodity is yellowfin tuna (Thunnus albacares). Research on the effect of the distribution of sea surface temperature in the Indian Ocean south of Java on the catch of yellowfin tuna (Thunnus albacares) has been carried out at the Nizam Zachman Ocean Fishery Port (PPS) from April 8 to April 30, 2021. This study aims to determine the effect of sea surface temperature (SST) on the catch of yellowfin tuna. The research method used was the method of observation and analysis of satellite imagery. Coordinate data and the number of catches were obtained from the Ocean Fishery Port Logbook (PPS) Nizam Zachman. SPL data obtained from satellite imagery Modis Aqua Level 3. The data was obtained and then analyzed using a simple regression test and the F test results of regression analysis showed that the correlation coefficient (R) of 12.7% and the coefficient of determination (R2) of 1,6% means that 1.6% of yellowfin tuna catches are influenced by SST and 98.4% is influenced by other factors. The F test results show that the SPL significance value is 0.332. The conclusion is that changes in SST have no significant effect on the catch of yellowfin tuna

Abstract

This research was carried out in February 2021 in the Historic River Mangrove Tourism Area, Kayu Ara Permai Village, Sungai Apit District, Siak Regency, Riau Province. This study aims to analyze the rate of decomposition of inter mangrove litter. The method used in this study is a survey method and the determination of the sampling location by purposive sampling. The rate of decomposition of mangrove leaf litter was carried out by placing 10 g of litter in a litter bag on the mangrove forest floor in three zones for 4 weeks and taken every week as a sample. The results showed that the water quality, namely the temperature ranged from 28-30 °C, salinity 30-31‰, and pH 6.1-6.4. The results of the calculation of the rate of decomposition of mangrove leaves obtained an average of 0.25–0.11 g/day. The results of the Anova test showed that the rate of decomposition of mangrove leaf litter was higher in zone 1, which is relatively always inundated by tides and is affected by sea waves.

Abstract

Natural factors such as geomorphology, waves, tides, coastal building materials, and altitude can have an impact on marine vulnerability. Coastal vulnerability is impacted by human activities such as logging of mangrove trees, tourism object activities, and manufacturing, in addition to natural influences. This study was carried out in February 2021. The goal of this study was to calculate the rate of change of the Agam Regency coastline from 2010 to 2020, as well as to map the level of vulnerability of the Agam Regency shore. According to the findings of the study. Pesisir Subdistrict, Agam Regency is classified into five levels of vulnerability, namely very not vulnerable, not vulnerable, moderate, vulnerable and very vulnerable. Very low to high levels of vulnerability can be found along the coast of Agam Regency. The annual accretion rate ranges from 0.12 to 15.98 m. The erosion rate ranges from 0.07 to 10.21 meters per year

Abstract

The Mangrove Education Center is located in Pangkalan Jambi Village, Bukit Batu Sei District. Pakning Bengkalis Regency which has the potential to be developed into a mangrove ecotourism area, because almost along the coast is overgrown with mangrove ecosystems and has abundant biota. This study aims to identify the potential of biota using the transect method as a mangrove ecotourism area. Data collection was carried out from January to February 2022 in Pangkalan Jambi. The research method used is purposive sampling. The research area was taken as many as 3 stations. Data analysis is based on the number of biota found in each station. Parameter data for mangrove tourism suitability consists of biota objects. The results of the measurement of the suitability of mangrove tourism parameters are the number of biota at station I with 35, station II at 30 and station III at 38. Found 4 species of biota with others such as: fish, shrimp, crabs, mollusks, reptiles, birds, and other biota. The results of this study indicate that this mangrove forest spans an area of ​​3 hectares along the coastline of Pangkalan Jambi Village. the most influential for the sustainability of the mangrove ecosystem.

Abstract

This research was conducted from July to October 2021 in Bengkalis Regency. This research is focused on evaluating in detail the condition of the ultimate fisheries from the ecological, social, economic, and institutional aspects as well as scientific information for follow-up planning and implementation of the best fisheries management in the waters of the Bengkalis Strait. The research method used during the study was a survey method. Types and sources of data used in this study are primary data and secondary data. The number of key respondents used in this study were 30 people. Sustainable fisheries management is seen from five dimensions, namely the ecological dimension, the economic dimension, the social dimension, the technological dimension and the institutional dimension. The scores for each attribute were analyzed using the Rapfish technique and will be passed through several analyzes such as multi-dimensional scaling (MDS), leverage analysis (JackKnife), and Monte Carlo analysis. Based on the results of the study the results of the catch of the terubuk fish during the period June-September amounted to 160 fish. From this amount, it showed that the percentage of male fish caught was much more dominant, namely 110 fish (69%) than 50 female fish (31%). The results of the analysis of each dimension show that the ecological index (59.92%) is included in the moderately sustainable category, the economic dimension (52.94%) is included in the moderately sustainable category, the social dimension (50.54%) is included in the moderately sustainable category, the social dimension (50.54%) is included in the moderately sustainable category. Institutional (49.91%) is included in the sustainable category and the technological dimension (70.25%) indicates the category is quite sustainable. Thus, the design of the terubuk fish management in Bengkalis waters can use the dimensions of the attributes that are classified as quite sustainable, to support or improve the institutional dimensions in order to support the management of terubuk fish
