Abstract

Dry system transportation using the principle of hibernation aims to suppress the metabolic processes of an organism so that in minimum environmental conditions the organism can survive. The survival of freshwater crayfish during transportation using the dry system is strongly influenced by the position of the lobsters in the packaging and the temperature of the media. This study examines the effectiveness of rice straw media in the transportation of crayfish with a comparison medium consisting of sponges and sawdust which are commonly used in the process of transporting crayfish. Research results on the survival rate of freshwater crayfish using rice straw media provide the most efficient survival results among other media. The process of transportation with different media had a very good survival impact on crayfish starting from treatment A using (sponge) with an average survival rate of 16.7 heads or (83.5%) of 20 heads. Treatment B used (wood powder) with an average survival rate of 17 or (85%) of 20 individuals. Treatment C used rice straw with an average survival rate of 18.3 individuals or (91.5%) of 20 individuals. The conclusion in this study is that the survival of freshwater crayfish using rice straw media provides the most efficient survival results among other media

Abstract

Salin tilapia (Oreochromis niloticus, Linn) Is a type of fish consumed in brackish water with an elongated body shape and flattened to the sides and blackish white in color. Tilapia aquaculture is a promising activity for the main actors in fisheries because the demand for tilapia is very high and tilapia aquaculture is an activity that is easy and fast to implement. The purpose of this study was to determine the feasibility of intensive saline tilapia cultivation by the Perkasa Fish Farmers Group (Pokdakan) in Karangrejo Village, Manyar Gresik District. In this study, data collection methods were used including primary data and secondary data, to calculate business feasibility, financial analysis was carried out such as operational costs, net income and BCR. The difference in variable costs is influenced by the size of the business being run. The larger the scale of the business being run, the greater the variable costs incurred. Vice versa, the smaller the business scale, the smaller the variable costs incurred. To increase income, the population size should be increased because the higher the business population, the higher the income.
