The main construction of the purse seine is wings, body and bag. The mesh size of each part is different. The wings have a mesh size of 10.16 cm, body 7.62 cm and bag 2.54 cm. Mesh size greatly affects the size of catch. Fish morphometric which is strongly influenced by mesh size is fish body girth. A mesh size larger than the body girth will allow fish to escape from the net and a smaller mesh size will trap fish by gilled, snagged or wedged. The purpose of the study was to distribute the frequency of the length and body girth of mackerel, analyze the relationship between length, body girth and mesh size of the purse seine. The research method used is experimental fishing for 2 trips. Analysis of the data used is linear regression, the formula for the width of the purse seine mesh opening and determination of body girth coefficient based on mesh size. The results showed that the minimum value of mackerel length was 35 cm and the maximum value was 57 cm. The highest length frequency distribution was at the size of 41-43 cm. The minimum value of fish body girth is 23 cm and the maximum value is 44 cm. The highest value in the body girth frequency distribution of fish was 29-31 cm. The relationship between length and body girth has a value of y=0.72x–1.91. The correlation value of body girth and mesh size is 0.82 and has an average body girth coefficient of 0.084 in the bag, 0.251 body and 0.335 wings. The fish body girth coefficient value is smaller than the standard. This means that mackerel caught tend to be wedged in the wings, gilled in the body and snagged in the bag.Key Words: Body Girth; Mackerel; Mesh Size; Purse Seine

Lomek fish is a typical fish that is often found in the province of Riau, one of which is in Dumai. The stable production of lomek fishery in Dumai makes it necessary to have more management so that the catches obtained by fishermen are not only sold in the form of raw processing, but also in ready-to-sell products. The high potential of fish resources makes several products appear, one of which is churros made from lomek fish. This product diversification is also expected to improve the economy in Dumai City through MSMEs. The purpose of this study is to recommend a fish churros business development strategy using SWOT analysis. The results obtained are fish churros business based on SWOT analysis is in quadrant 1, namely the processing business must carry out aggressive efforts by taking advantage of strengths and opportunities, strategic recommendations that can be carried out are food certification, product registration in delivery services, collaboration and marketing in several markets. place, adding some variety to the taste of the product and providing price promotions to consumersKey Words: SWOT; Strategy; Business; Diversiification

Dogamit Swamp is one of the swamps in the Merauke Wasur National Park, which stores an abundant diversity of fish and biota. This study aims to examine the diversity of fish species in the waters of Rawa Dogamit. The research was conducted from July to August. The method of data collection was by determining 3 locations of observation stations, at each station an identification of all species and their environmental factors was then linked to the Diversity index, Abundance Index, Evenness Index, and Dominance. The results obtained from the study are that there are 15 species of fish, which have the highest abundance of Betik (Anabas testudineus) by 35.74% and the lowest is the Moon Fish (Megalops cyprinoides) by 0.05%. Measurement of the Diversity index is categorized as moderate, whereas for the Evenness index is categorized high at stations I and II, while station III is categorized as moderate. For the measurement of the Dominance Index, it is categorized as low or not dominant. It was concluded that there was a significant relationship between the diversity, evenness and dominance index with environmental parameters both for the survival of fish in Rawa Dogamit waters.Key Words: Diversity; Fish; Dogamit Swamp

Climbing perch (Anabas testudineus Bloch, 1792), one of the types of fish that is able to survive in freshwater and brackish water, which belongs to the type of Blackwater fish. The study aims to determine the reproduction of Climbing perch (Anabas testudineus Bloch, 1792) at Wasur Swamp. The fish sampling was conducted in May to July 2019, with catching using a mesh of gills measuring the net-size 2.5 cm. Analysis used is the genital ratio, the maturity level of gonads (TKG), the Maturity index gonads (IKG) and fecundity. The whole fish was acquired during the study amounting to 380 tails consisting of 211 males and 169 females. The genital ratio gained during the study was 1.2:1. The spawning peak for three months of observation of the female fish of TKG IV occurred in May at the I Station. The fecundity of the Climbing perch ranges from 1.984 to 73.795, at a total length range of 105–159 mm and a total weight of 28 - 84 grams.Key Words: Climbing perch; Anabas testudineus; Reproduction; Wasur Swamp

Heavy metals are hazardous pollutants because they are toxic. If present in large quantities, it can affect the ecological and biological aspects of waters. Heavy metals are included in the group of dangerous pollutants because they have non-biodegradable properties and are easily absorbed or precipitated. This study aims to determine the concentration of heavy metals Pb, Cd, Cu, and Zn, oceanographic parameters, and pollution index in the waters of Yos Sudarso Bay. Sampling points are in three locations with consideration as pollutant-producing locations. The analysis of sea water quality was carried out descriptively by comparing the results of the analysis with sea water quality standards based on the Decree of the Minister of the Environment Number 51 of 2004 and the pollution index method to see the pollution category. The results showed that the concentration of heavy metals Pb, Cd, Cu, and Zn had exceeded the water quality standard based on the Decree of the Minister of the Environment Number 51 of 2004. For water parameters, namely the temperature had exceeded the water quality standard. standard. standard. quality standard, DO and salinity are less than quality standard, pH is below quality standard, phosphate and nitrate exceed the quality standard based on the Decree of the Minister of the Environment Number 51 of 2004. The pollution index for stations 1, 2 and 3 is lightly and moderately polluted.

Sponges are marine organisms that are filter feeders so that they become a habitat for microorganisms. Microorganisms symbiont and sponge produce secondary metabolites as self-protection mechanisms which are then used to find active compounds that are useful for medicine (pharmacology). The aim of this study was to isolate the active fraction of the fungal symbiont sponge and Characterization mikroskopiks of fungal symbionts sponge which has bioactivity as antifungals against Trichophyton sp. Sponge was taken from Opiaref Sea, Biak Numfor, Papua. Fungal symbiont of sponges was isolated by direct plate method. Purification of fungal symbiont was conducted by streak-plate method. Bioactivity assay of fungal symbiont sponges against Trichophyton sp. was conducted by agar diffusion method. Purification of bioactive compound was conducted by separatory funnel, TLC and OCC. Characterization of fungal symbionts sponge by mikroskopiks. Fungal symbiont from sponge C1K1 has best bioactivity as antifungal against Trichophyton sp. are fungi with the isolates MT.C12 and MT.C14. Isolation of bioactive compound obtained 2 fractions that best in inhabiting fungi Trichophyton sp. Diameter of inhibition zone of MT.C12-1-6 (13,44 mm) and MT.C14-1-4 (7,43 mm). TLC visualization with vanilin sulfuric acid indicated that MT.C12-1-6 and MT.C14-1-4 fraction form pink spots. Based on the color formed on both fractions containing alkaloids. Alkaloids are compounds that have biological activity of and provide certain physiological effects on organism.
