Giant freshwater prawns (Macrobrachium rossenbergii) were still been the favorite prawn catch of local fishermen in the Labuhanbatu district. This raises concerns for the survival of these animals. Therefore, it is necessary to conduct a study to obtain bioecological information on this giant freshwater, giant prawns in the Bilah river especially inform about condition the abundance based on gonad maturity levels, and the growth patterns of Giant freshwater prawns (M. rossenbergii). This study was conducted at 3 stations around the Bilah river. These stations were determined using a purposive sampling method. Furthermore, sampling was carried out using fishing nets. After that, the caught fish were analyzed to find out the Fulton’s condition factor, the abundance of prawns based on gonad maturity levels, and the growth patterns. The results of growth patterns analysis which calculate from the relationship of carapace length and body weight of M. rossenbergii caught were showed negative allometric category (b value 1.88 to 2.577). Meanwhile, the abundance of giant freshwater prawns based on gonad maturity levels for males and females were dominated by immature prawns (ranging from 46.15 to 54.65%).

Penelitian ini bertujuan untuk mengetahui faktor kondisi (K) dan Pola Pertumbuhan udang kelong (P. indicus) telah dilakukan di sekitar perairan muara yang memiliki ekosistem mangrove Belawan selama 3 bulan, sejak bulan Juni - Agustus 2016. Metode penelitian yang digunakan yang dalam menentukan 4 titik stasiun sampling adalah purposive random sampling dengan 2 kategori zona yaitu zona alami dan zona pemanfaatan. Pengambilan sampel udang kelong (P. indicus) dilakukan dengan menggunakan jaring ambai berbentuk kerucut yang terbuat dari bahan nilon. Pada tiap stasiun ditentukan 3 unit jaring tangkap sebagai ulangan (total jaring 12 unit/bulan). Analisa data pola pertumbuhan udang menggunakan rumus persamaan hubungan panjang dan bobot Effendie (2002) dan analisa faktor kondisi relatif (K) menggunakan rumus Rypel dan Ritcher (2008). Hasil penelitian diperoleh bahwa Pola pertumbuhan udang (P. indicus) di perairan mangrove Belawan seluruhnya kategori allometrik negatif (b < 3) dimana nilai b tertinggi pada stasiun I sebesar 2.82, dan terendah berada pada stasiun III sebesar 1.26. Hal ini kemungkinan dipengaruhi oleh letak lokasi stasiun I yang hampir mendekati daratan, sehingga diduga kondisi substrat sesuai bagi kebutuhan perkembangan udang kelong. Nilai faktor kondisi (K) P. Indicus tertinggi berada pada stasiun II sebesar 1,71 dan nilai yang terendah pada stasiun III sebesar 1,20. Sehingga dapat disimpulkan udang kelong (P. Indicus) pada seluruh stasiun tergolong dalam kondisi pipih atau tidak gemuk.

The study aimed to determine the diversity of ichtyofauna species has been done in the Tambatan’s River, North Labuhanbatu Regency. This research applied by purposive sampling method to decided sampling collection which based on the environmental conditions of Tambatan’s River. Fish samples were collected using cast nets and gillnets. The collected data were analyzed using the Shannon-Wiener diversity index, evenness index, dominance index, similarity index, and Pearson’s correlation analysis. The results found 20 fish species from 5 families on Tambatan’s River. The largest family of fish species found from Cyprinidae’s (12 species), Bagridae’s (5 species), and the lowest found from Siluroidae’s, Mastacembelidae’s, Gobidae’s family an each 1 species. The result of the diversity index indicated that the 3 stations were classified in the medium category with range of 0.53-1.87. The result of pearson’s correlation describe fish biodiversity has strong positive correlation value to current velocity (0.927) and water transparency (0.927).

Mangrove crab (Scylla serrata) is one of the prima donna sources of protein caught by fishermen around mangrove forest waters in the waters of the Barumun River Estuary, Labuhanbatu Regency. This study aims to inform about condition factors, growth patterns of crab populations, and reproductive aspects in the form of abundance of Gonad Maturity Level (TKG). Determination of 3 sampling points is done by using purposive random sampling method. Scylla serrata sampling was carried out using Bubu. Data analysis presents information on the abundance of gonadal maturity level, growth pattern, and Fulton condition factor (K), which is presented quantitatively. The results showed that male and female Scylla serrata growth patterns were categorized as negative allometric b < 3, with carapace width growth being faster than weight gain. Fulton condition factor (K) values obtained ranged from 50.14-132.75 for male Scylla serrata, and female ranged from 80.34-123.94. The gonadal maturity level of Scylla serrata was dominated by TKG II crabs, and the lowest abundance of gonad maturity was in TKG IV crabs. This indicates that, in December-February, the condition of the Scylla serrata population around the mangrove forest waters of the Barumun river estuary, is predicted to be in the stage of adult dominance that is ready to reproduce and prepare to spawn.

This study aims to examine the bioecological aspects of P. merguiensis around the estuary of the Berombang river in terms of growth patterns, the abundance of gonad maturity and condition factors. The method used in this research is purposive sampling. Shrimp sampling was carried out using arad nets which were stocked at low tide. The results showed that the composition of the abundance of the gonadal maturity level of P. merguiensis shrimp at three sampling stations was dominated by immature gonadal shrimp (BMG) to TKG 2. The growth pattern of P. merguiensis shrimp based on the length-body weight relationship in the Berombang river was classified as positive allometric. Fulton condition factor (K) ranged from 0.14 to 4.68, with an average total body length ranging from 2.35 to 13.70 cm. In conclusion, the condition factor of P. merguiensis shrimp in the Berombang river was classified as a plump category with shrimp weight gain being faster than body length growth, with female plumpness being greater than males. Keywords: Fulton Condition Factor, Gonad Maturity, Growth Pattern, P. merguiensis, Berombang River

Phytoplankton is the most important organism for aquatic ecosystem life that make up organic substances from inorganic substances in the process of photosynthesis and the largest oxygen producer for the life of living creatures. Research on the diversity of phytoplankton in river blades has never been done . The purpose of this study is to determine the biodiversity of phytoplankton in Bilah river and analyze the relationship of physical-chemical factors of the water to the diversity of phytoplankton. The study was conducted from April to June 2019. This research is an exploratory descriptive study with the selection of sampling locations using purposive sampling method. Analysis of data includes density of phytoplankton, measurement of physical-chemical factor of aquatic biology and the Correlation analysis between phytoplankton and value of physical-chemical factor. The results showed Nostoc sp.were the highest density of phytoplankton found on the first (1st) station, while the lowest abundance value is found on stations 2nd and 3rd were found genus Rhizosolenia sp. and Euglena sp. The Highest Shanon-Wiener index (H’) value on the first (1st) station (2.26) dan the lowest value on stasiun 3rd (1.24). The summary from this research were DO, temperature, and light intensity as physical factor of water had the highest correlation againts of biodiversity of phytoplanton.

The purpose of this study was to analyze the Gonad Maturity Level (TKG), Gonad Maturity Index (IKG), first gonad maturity size (L50), egg weight (fecundity) in Portunus pelagicus in Sei Barombang waters, Labuhanbatu Regency. The sampling point for Portunus pelagicus sampling was carried out in Sei Barombang waters. The research method used purposive random sampling to determine three sampling stations in the research area. Portunus pelagicus samples were taken using traps and trawl nets. The results of the study of Portunus pelagicus males and females were more dominant in TKG I. The IKG values for male Portunus pelagicus ranged from 8.85 - 15.59 and females ranged from 5.15 - 13.69. The male Portunus pelagicus crab experienced the first maturity of gonads measuring around 87.20 mmCW and females around 103.55 mmCW. Egg weight or fecundity in Portunus pelagicus in Sei Barombang waters, Labuhanbatu Regency ranged from 317.280 ± 1.897558 eggs.
