Abstract

Mangrove is one of vegetation on coastal where very important. The aim of research is to know the structure of community of mangrove forests in Dalapuli Barat Village Pinogaluman Sub-district, Bolaang Mongondow Utara District. The method to take the sample in this research is transek square method. The first sample plot is on the left of the path axis and the second sample plot is on the right of the path axis and then alternates. Sampling growth of 2 m x 2 m for the seedling phase, ie regeneration of trees that begin to increase until the power <1.5 m. Example plots are 5 m x 5 m for the stake, ie high regeneration> 1.5 m up to <10 cm in diameter, and. The sample plot is 10 m x 10m for the tree phase, ie trees having a diameter of more than 10 cm. The results of this study are: 8 species of mangrove species are found in Rhyzopora apiculata, Xylocarpus granatum, Cheriops tag, Sonneratia alba, Nypa fruticans, Lumnitzera littorea, pandanus techtorius, and Acanthus ebracteatus The essential tree index value (INP) is 302, Pancang is 302, (scale 0 - 300 and seedling level includes 313. Index diversity of analysis result is low. Keywords : Mangrove, Community, Dalapuli Village

Abstract

Ikan Huluu merupakan salah satu ikan air tawar yang dapat ditemukan di Danau Limboto. Kondisi perairan Danau Limboto yang terus menurun akibat sedimentasi dan limbah domestik. Akibat dari kondisi tersebut berdampak pada habitat organisme perairan termasuk ikan Huluu. Penelitian ini bertujuan untuk mengetahui hubungan tingkat Kematangan Gonad (TKG) dan fekunditas ikan Huluu (Gurius margaritacea) di Danau Limboto. Penelitian dilaksanakan selama 3 bulan. Tingkat Kematangan Gonad diamati secara morfologi dan penentuan fekunditas diamati dengan metode volumetrik dan gravimetrik. Hasil penelitian menunjukkan bahwa pada TKG IV didominasi oleh ikan Huluu Betina. Fekunditas tertinggi yaitu 16866,7 butir dan terendah yaitu 1400 butir. Hubungan TKG dan fekunditas berbanding lurus, semakin tinggi TKG maka nilai fekunditas juga semakin tinggi. Kata Kunci : Ikan Huluu, TKG, Fekunditas, Danau Limboto

Abstract

This research aims to identificated the composition of the type and seagrass beds density in malagoso beach, Dulomodo Village. The data was undetaken by survei method and transect square method. There are 3 stations where every stations will cut in 3 times. The analysis used and covering identification of the type of seagrass beds, density, coverage of seagrass and the closure of the parameters of the enviroment. The results of identification to research is found 4 types species of seagrass, there is  Enhalus acoroides, Cymodocea serurulata, Halophila ovalis, Syringodium isoetifolium. Seagrass beds density ranged from 20 tegakan/m -600 tegakan/m. The parameter of water quality there are temperature 200C, salinity31 ppt, pH 8,2, brightess about 0,2-1 meters, the substrates are muddy and rocky.Keywords : Seagrass density, The seagrass bed, Malagoso beach.

Abstract

The purpose of this research is to analyze suitability salt pond in the Siduwonge Village, Randangan Distric, Pohuwato Regency. This research used spatial analysis and laboratory test to know salt qualities. Result of this research show that salt from Siduwonge Village is quite suitable for use as consumption salt and industrial salt. Spatial analysis of salt ponds found that  salt fields area belong to S1 category was ±183 ha, salt fields area belong to S2 category was ±1,109 ha and area belong to N category was 6,652 ha.

Abstract

Tujuan penelitian ini adalah untuk mengetahui karakteristik biologi ikan layang dan laju eksploitasi ikan Layang yang ada di perairan Gorontalo Utara. Pengambilan sampel ikan dilakukan dari bulan Mei-Agustus 2021 dengan mengukur panjang total dan pengamatan kematangan gonad yang dilakukan Pengamatan TKG akan dilakukan menggunakan mikroskop. Hasil penelitian menunjukkan bahwa sebaran panjang total berkisar antara 15,5 – 22,5 cm, nilai eksponen b < 3 sehingga memiliki pola pertumbuhan bersifat allometrik negatif yang berarti pertambahan berat lebih lambat dari pertambahan panjang. Nisbah kelamin ikan Layang jantan dan betina tidak berimbang yaitu 2,277 : 1. Ikan yang tertangkap didominasi tingkat kematangan gonad tingkat III - IV. Estimasi nilai parameter pertumbuhan dimana panjang asimtotik adalah 23,6 cm; Nilai koefisien pertumbuhan per tahun adalah 0,67 cm. Nilai panjang pertama kali matang gonad lebih kecil dibandingkan dengan ukuran panjang rata-rata tertangkap serta laju eksploitasi ikan layang yang didapatkan melebihi rasio eksploitasi seimbang diindikasikan dapat mengganggu stok ikan layang di perairan. A B S T R A C T The purpose of the study was to determine the biological characteristics and rate exploitation of scad in the waters of North Gorontalo. Fish sampling was carried out by measuring the total length and observing the maturity of the gonads from May – August 2021. The results showed that the total length distribution ranged from 15.5 – 22.5 cm, growth pattern of Decapterus russelli was negative allometric, which means the weight gain is slower than the length gain. The sex ratio of male and female fish was 2,277 : 1. The fish caught are dominated by the level of maturity level of the gonads III - IV. The estimated value of growth parameters where the asymptotic length is 23.6 cm; The value of the growth coefficient per year is 0.67 cm. The value of the length at first maturity of the gonads is smaller than the average length caught and the exploitation rate of scad that is obtained that exceeds the balanced exploitation ratio is indicated does not support the balance stock of scad in the waters.
