The potential for developing marine tourism in Sikabau Beach focuses on integration with the local salted fish processing industry and the importance of synergy between the two sectors, considering that Jorong Sikabau has stunning natural beauty and maritime traditions, including salted fish processing that has been passed down from generation to generation. However, the salted fish processing industry still faces challenges, such as limited market access, lack of technical knowledge, and inadequate infrastructure. This study aims to describe the tourism picture and characteristics of salted fish processors and analyze the empowerment of salted fish processors. The method used in this study is a case study method using a qualitative approach. The selection of informants in this study was purposive. The data analysis used was qualitative, starting from data reduction, data display, and drawing conclusions. The study results showed that the characteristics of Sikabau Beach marine tourism are mangrove forest tourism, Batu Kajang, and the estuary of Sikabau Beach. The attributes of salted fish processing businesses are that they still carry out the processing process traditionally. The empowerment carried out for salted fish processors is training in processing fish-based products and their marketing, fish packaging, and how to reproduce good processed food. The programs that have not been implemented are business strengthening and strengthening the added value of products. Therefore, there needs to be support from the government that focuses more on skills training for salted fish processors and the development of adequate infrastructure for salted fish processors

Luciocephalus pulcher lives in peat swamps, and the male incubates the eggs in the mouth. A study aimed to determine morphometric characters and differences in the oral structure of male and female fish was conducted from June to July 2024. Fish samples were caught in the upper Sibam River. 5 times, once/week. The morphometrical characteristics were measured, and the fish mouth structure was observed. Results showed that 32 fish were caught, consisting of 21 males and 11 females. Of the 37 morphometric characters observed, 18 differed between males and females. These characters included total length, head length, body height, caudal peduncle height, eye diameter, anal fin to caudal fin base distance, dorsal fin base length, pectoral fin base length, anal fin height, ventral fin base length, caudal fin base length, lower jaw length, upper jaw length, lower jaw width, gular sac width, lower lip length and upper lip length. The total length of male fish ranged from 48-135 mm, while females were 48-135 mm. Fin characteristics in male and female fish were the same, with the formula D.I, 8-12 P.12-15 V.6-7 A.I, 14-20 C.13-15. The difference in mouth characters was seen in the gular sac. The gular sac of male fish was wider with thicker tissue, more folded, more flexible, elastic skin tissue, and smaller, more flexible hyoid bone. In contrast, female fish have smaller, less elastic gular sacs, thinner tissue, and less folded and thicker hyoid bone.

Danau Panjang is a natural lake located in Lubuk Siam Village. The variety of activities in Danau Panjang can affect phytoplankton biodiversity. Phytoplankton is an important factor for the life of fish and all kinds of biota that live in water as primary producers. The presence of phytoplankton will determine the quality and condition of a body of water. Danau Panjang, as one of the oxbow lakes, currently rarely has any additional discharge from the main river, so it is feared that phytoplankton diversity will be low. This study aims to determine the type and abundance of phytoplankton and phytoplankton biodiversity and the results of the analysis of environmental factors on phytoplankton biodiversity in Danau Panjang. Phytoplankton biodiversity and water quality parameters consisting of temperature, brightness, depth, pH, CO2, DO, nitrate, and phosphate were observed in September-October 2023. Phytoplankton samples and water quality measurements were taken at three sampling points, three times with an interval of two weeks. Phytoplankton abundance ranged from 2383-7098 cells/L, and 10 phytoplankton classes were found. Phytoplankton biodiversity in Danau Panjang illustrates a relatively stable condition. The species richness index in Weeks 1, 2, and 3 ranged from 3.51-5.52 in the good category. The diversity index in Weeks 1, 2, and 3 ranged from 2.06-3.82, with a high level of diversity. The dominance index in Weeks 1, 2, and 3 ranged from 0.12-0.38, indicating that there was no dominant species. The uniformity index in Weeks 1, 2, and 3 ranged from 0.39-0.69, where uniformity was in balance. In general, the water quality in Weeks 1, 2, and 3 is not much different and is favorable for phytoplankton growth when viewed from the quality standards of class III of PP No. 22 of 2021
