Anthropogenic activities that tend to be exploitative in the mangrove ecosystem of Belawan are thought to have an impact on the biota associated with the ecosystem. One of the impacts is thought to be implied by mantis shrimp Cloridopsis scorpio (Latreile, 1828). The reproductive biology of the shrimp is the main object that needs to be studied in relation to the impacts. This study aims to determine the distribution of gonad maturity stage, gonad somatic index, and the length of the first mature of C. scorpio in the Mangrove Ecosystem of Belawan, North Sumatera. The research was conducted on March to May 2019 with a biweekly sampling period. The purposive random sampling was applied to choose three sampling stations in the research location. Mantis shrimp samples were caught using shrimp trawl. The result showed that the gonad maturity stage of males and females were dominated by Stage I. The gonad somatic index (GSI) range of males were 7.00-10.93 and female were 7.40-11.15. The GSI value of C. scorpio is closely related to its gonad maturity development. The length of the first mature (L50) of males were 205.50±10.65 mmBL and females were 186.0±10.48 mmBL.Keywords: Cloridopsis scorpio, Gonad maturity stage, Gonad somatic indeks, Length of the first mature ABSTRAKAktivitas antropogenik yang cenderung eksploitatif di kawasan ekosistem mangrove Belawan diduga telah berdampak terhadap biota-biota yang berasosiasi dengan ekosistem tersebut. Salah satu dampaknya dialami oleh udang mantis Cloridopsis scorpio (Latreile, 1828). Aspek reproduksi C. scorpio menjadi salah satu objek yang perlu dikaji berkaitan dengan dampak tersebut. Penelitian ini bertujuan untuk menganalisis sebaran tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), dan ukuran pertama kali matang gonad (L50) dari C. scorpio di ekosistem mangrove Belawan, Sumatera Utara. Penelitian dilakukan pada bulan Maret sampai Mei 2019 dengan periode pengambilan sampel dua mingguan. Metode purposive random sampling digunakan untuk menentukan tiga stasiun pengambilan sampel di lokasi penelitian. Sampel C. scorpio ditangkap menggunakan pukat udang. Hasil penelitian menunjukkan distribusi TKG C. scorpio jantan dan betina didominasi oleh TKG I. Nilai IKG C. scorpio jantan berkisar antara 7,00-10,93 dan C. scorpio betina berkisar antara 7,40-11,15. Nilai IKG C. scorpio berkaitan dengan tahap perkembangan gonadnya. C. scorpio jantan mengalami pertama kali matang gonad (L50) pada ukuran 205,50±10,65 mmBL dan C. scorpio betina pada ukuran 186,00±10,48 mmBL.Kata kunci: Cloridopsis scorpio, TKG, IKG, Ukuran pertama kali matang gonad

Background: Waanders's hard-lipped barbs or scientifically known as Osteochilus waandersii belong to the family Cyprinidae with the potamodromous category. This fish can be found in the Tambatan river. It has the potential for commercial consumption or ornamental fish. Methods: This study was conducted in the Tambatan river from November to January 2021. The determination of three research stations was carried out using a purposive sampling method. Sampling was undertaken using cast nets. Furthermore, data analyzed were growth patterns, condition factors, and gonad maturity levels. Results: The growth patterns of male (1.944) and female (2.379) Osteochilus waandersii were in a negative allometric category. Besides, The Fulton's condition factor for male fish ranged from 0.42 - 3.43 with an average of 1.05, while that for female fish ranged from 0.59 - 3.67 with an average of 1.47. The result of the observation on the gonad maturity level for male and female O. waandersii in the Tambatan river indicated that they were dominated by fish with gonad maturity stage I (immature). Conclusions: Waanders's hard-lipped barbs O. waandersii found were in the stage towards the mature level.

Background: Mantis shrimp is one of the favorite shrimp caught by fishermen around the estuary waters of Berombang River, Labuhanbatu Regency. This study aimed to determine the condition factors and growth patterns of mantis shrimp population. Method: Three station points were determined using a purposive random sampling method. The sampling of Harpiosquilla raphidea was carried out using trawl nets. The data analysis provided information on growth patterns and condition factors. Result: The results showed that the growth patterns of male H. raphidea belonged to the positive b> 3 allometric category, where weight growth was faster than carapace growth. Moreover, the growth patterns of female H. raphidea belonged to the negative b<3 allometric category, where the carapace growth was faster than body weight growth. The value of Fulton (K) condition factors for male H. raphidea ranged from 3.54 to 13.18, and for females, it ranged from 15.28 to 22.09. The value of correlation analysis of Physic-chemical parameters, water temperature (0.935) and DO (0.832) showed the high category correlation test results. Conclusion: This result showed that from November 2021 to January 2022, the condition of H. raphidea population around the estuary waters of Berombang River was known and predicted to be in the adult stage

Background: The potential fish resources of snakeskin gourami (Trichopodus pectoralis) in the flooded swamp waters of Bilah river, Labuhanbatu Regency, are pretty high. Thus, this is one of the essential resources and has economic value. This study aimed to inform the bioecological aspects of snakeskin gourami fish (T. pectoralis). Methods: The determination of 3 sampling points was done using the purposive random sampling method. The sampling of T. pectoralis was carried out using the trap. The data analysis presented information on the abundance of Gonad Maturity Level, growth pattern, the Fulton (K) factor condition, and the Pearson correlation among environment parameters to the T. pectoralis population, which was presented quantitatively. Results: The results showed the length-weight relationship of T. pectoralis in the allometric category. The average relative weight (Wr) for male T. pectoralis was 100.46 ± 8.37, and for females was 99.83 ± 2.30. The mean value of the Fulton’s (K) factor condition in male T. pectoralis (8.94 ± 0.54) and female T. pectoralis (9.27 ± 0.67). Conclusions: T. pectoralis showed an allometric category and domination of the first gonadal maturity level. It describes that the female is abundant in optimum condition and ensures for future generations, and Pearson’s correlation result informs that increasing the value of environmental parameters will affect the optimization of T. pectoralis life.

Betta cf raja termasuk cupang liar (wild Betta) endemik dari Pulau Sumatera. Betta cf raja menjadi target buruan untuk dijadikan ikan hias dikarenakan di pasaran harga cukup mahal. Produksi masih mengandalkan hasil tangkapan, sehingga populasi di alam mulai sulit ditemukan. Belum lagi dampak konversi lahan dan masalah lingkungan. Tujuan penelitian ini adalah menganalisis karakteristik habitat Betta cf raja berdasarkan parameter fisika kimia perairan di Pulau Sumatra. Penelitian ini bersifat eksploratif yakni dengan langkah mencari wilayah yang menjadi habitat alami berdasarkan informasi kunci (pengangkap cupang liar). Analisis data menggunakan uji Krusskal Wallis dan Mann Whitney dengan software Statistical Package for the Social Sciences (SPSS) dan Principal Component Analytical (PCA) dan Unweighted Pair Group Method with Aritmhmetic Averange (UPGMA) dengan software Multi Variate Statistical Package (MVSP). Hasil uji Kruskall Wallis seluruh parameter uji menunjukan hasil signifikan. Selanjutnya dilakukan uji Mann Withney yang menunjukkan pada Stasiun 1 dan 2 parameter yang nilainya signifikan adalah suhu, nitrat, dan phospat. Pada stasiun 1 dan 3 yang signifikan adalah nitrat dan Stasiun 2 dan 3 juga nitrat. Berdasarkan hasil uji PCA menunjukkan bahwa BOD, COD, kekeruhan, konduktivitas, dan TDS sebagai penciri utama habitat Betta cf raja di Pulau Sumatra. Hasil uji UPGMA antar lokasi pengamatan menunjukan nilai similaritas Jambi (75%) dan Riau dan Sumatra Utara (88%).
