Abstract The objectives of this study were to identify the social strata/layers of the fish farming community in Samarinda City and to determine the strategy for aquaculture development in Samarinda City. Respondents in this study were selected using purposive sampling with a total of 26 respondents from fish farmers and 5 staff of the Fisheries Service. Data were analyzed using descriptive qualitative and quantitative and SWOT analysis. The results of the study found that there are two social stratifications in the cultivation community in Samarinda City, namely middlemen/collecting traders and owner fish farmers. Positions as middlemen/collecting traders and fish farmers are status roles that are obtained because they are fought for through their own choices or efforts (achieved status). The top social layer is occupied by middlemen or collecting traders by looking at the level of wealth owned (ownership of vehicles, living conditions and ownership of luxury goods). The strategy that can be carried out for the development of aquaculture in Samarinda City is an aggressive strategy, namely optimizing technology and infrastructure to support the marketing of aquaculture products.

The capital market is one of the alternative sources of long-term funding among various other alternatives for companies that need funds for the sustainability of the company. The capital market has an important role for the economy of a country because the capital market performs a function, namely as a means for business funding or as a means for companies to obtain funds from the investor community.   For this reason, it is necessary to expand research that is supported by a basic theory, so the problem of factors capable of predicting changes in stock prices is proposed, where there are two variables that are thought to have an effect on changes in stock prices in this study. The two variables are asset structure and firm size. In addition, based on various previous research results, it was found that there were gaps or inconsistencies in the research results (gap research) conducted by researchers. On this basis, the title adopted from this research is "The Effect of Asset Structure and Company Size on Share Prices in Pharmaceutical Sub-Sector Companies on the Indonesia Stock Exchange".
