Abstract

This research was conducted at 3 stations in the seagrass ecosystem of the Tongkeina coastal waters district of Bunaken Darat Manado on March 16, 2019, at 10:35 - 13:45 WITA. This study aims to know the types and community structures of phytoplankton in the Tongkeina seagrass ecosystem and its environmental conditions. The method used to collect the sample is sampling. Samples were taken using a plankton net measuring 20 cm in mouth diameter with a mesh size of 60 microns. Based on the results of observations obtained by the composition of phytoplankton species, namely 17 genera of 22 species in 3 classes namely Bacillariophyceae, Cyanophyceae, and Pyramimonadophyceae. The highest density of phytoplankton in Tongkeina waters is at Station 2 (0.360 cells / l) with the highest relative density of Chaetoceros sp. (19.10%). While the highest density of phytoplankton is found at Station 3 (0.516 cells / l) with the highest relative density of Melosira sp. (21.69%). The lowest Diversity Index at Station 2 (H '= 2,217) and the highest at station 3 (H' = 2,284). This shows that overall these waters have moderate diversity values. The lowest Uniformity Index at Station 1 (e = 0.858) and the highest at Station 2 (e = 0.924). This shows that overall these waters have a medium uniformity value. The lowest dominance index at Station 3 (C = 0.119) and the highest at Station 1 (C = 0.127). This shows that no species dominate the waters. The water conditions such as temperature, salinity, pH, and brightness still support the growth of phytoplankton.Keywords: phytoplankton, community structure, seagrass, Tongkeina ABSTRAKPenelitian ini dilakukan pada 3 stasiun di  perairan ekosistem lamun kelurahan  Tongkeina kecamatan Bunaken Darat pada tanggal 16 Maret 2019 pukul 10:35 – 13:45 WITA, dengan tujuan mengetahui jenis dan struktur komunitas fitoplankton yang ada di perairan ekosistem lamun  Tongkeina serta kondisi lingkungannya.

Abstract

Sonneratia alba is a mangrove that is found in North Sulawesi and has been known to contain bioactive substances through researches. Rendement is the ratio of the dry weight of the extract to the amount of the raw material. Rendement value is related to the amount of bioactive content contained. The higher the rendement, the higher the bioactive componds contain in sample. The purpose of this study was to obtain the rendement value of Sonneratia alba leaves extract taken from Wori Village, North Minahasa Regency, North Sulawesi Province which was extracted using the infundation method with extraction time of 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes at boiling water solvent. Sample comparison of 50 gr : 3000 mL solvent (1:60 w / v). The results showed the lowest rendement in the 10 minutes treatment was 18.34% and the highest was in the 50 minutes treatment 29.76%. The rendement of leaves extract of this study has the possibility of qualitatively containing bioactive compounds that can act as antibacterial and antioxidant. Overall, it can be concluded that the extraction time affects the rendement, where the longer the extraction time, the higher the rendement.Key words: Rendement, Sonneratia alba, old leaf, infundation AbstrakSonneratia alba merupakan salah satu jenis mangrove yang banyak di temukan di Sulawesi Utara dan sudah dikenal mengandung zat-zat bioaktif melalui hasil-hasil penelitian.

Abstract

Economic and social prosperity is a dream of all traditional fishermen, particularly those who live in Malalayang I, Manado, North Celebes. This study used interviews to gather the information. Results found that 1) the local fishermen need to move to a semi-industrial fishing gear and boat in order to increase their catches; 2) the fishermen need to have an investment support to provide better fishing gears. Improvement in their economic and social conditions would bring improvements in social relationship among local fishermen.

Abstract

Effect of K+ concentration on growth rate, feed efficiency, potassium whole body, and osmoregulatory capacity of L. vannamei postlarvae Boone, 1931 were investigated. Treatments consisted of different concentration of K+ added to distilled water. Four treatments were set, namely A, B, C and D, where K2CO3 levels were 0, 30, 60 and 90 ppm, respectively. After the 42-days feeding trial, growth rate and potassium whole body of the shrimp under treatment D (90 ppm K2CO3) were significantly higher, while the value of osmoregulatory capacity in treatment A (0 ppm K2CO3) significantly higher than those under the other four treatments. The results indicated treatment C (60 ppm K2CO3) were the optimum K+ level for growth rate with increasing body size.

Abstract

Fisheries should be a sustainable economic activity in order to maintain its services in the future. Sustainable marine fisheries resources exploitation requires a utilization rate lower than the resources availability. Therefore, the exploitation rate should not achieve the recovery ability of the resources in any particular period. In fishing activities, for instance, there is a guideline not to catch fish over the Total Allowable Catch (TAC), 80% of the MSY value. The exploitation rate of the anchovy (Stolephorus sp.) in Dodinga Bay was still low. It could result from small-scaled traditional fishermen and low fishing distance from the shore. Their income was also low due to high operational cost and fluctuation in fish price. To improve the fishermen prosperity, it is necessary to raise the fishing productivity and the efficiency of production input utilization on the boat lift net. This study focused on understanding the anchovy fishing season of the boat lift net in Dodinga Bay to analyze the yearly fishing seasons for the last five years. Results concluded that the fishing season of the anchovy (Stolephorus sp.) in Dodinga Bay could be separated into two phases, March to June and October to November, but the former was more extensive and lager in scale than the later.
