The Reproductive ability of parent fish which just finish spawming are common with stage I of gonadal maturity takes for a long time. Gonad may not mature if it is notgiven treatment. Doses of OODEV between 0,3 – 07 cc/kgs body weight give effect in inducing gonadal maturation.This Research shows that the highest fecundity was an average of 33190 eggs obtained from on Treatment C, and the largest egg diameter was an average of 0,7 mm also obtained in the treatment C. The highest HIS score was in treatment C (0,95%), while the highest IGS value obtained in treatment A (13,183%). The result of the Observations on the gonad histology climbing perch parent fish was the treatment with OODEV hormones caused the development of maturity level. Change in values and levelsof water quality were considered metting the standard for live fish climbing perch fish. The statistical test result on all the above test parameters showed that al was notsignificantly different among all treatment given; thus from the given hypothesis HO wasaccepted and H1 was rejected which means that OODEV injection dose did not significantly affect the maturation procces. The treatmen with OODEV was more than the level without the use of OODEV Hormones (Control). This is because of the role of the FSH in OODEV Hormone influenced the development of biosytesis of estradiol -17 betha and gonad.

Lokasi penelitian terletak di PTPN IX Danau Salak, Kecamatan Astambul Kabupaten Banjar. Hasil penelitian menunjukkan bahwa nilai curah hujan peluang kejadian terlampaui 75% selama 10 tahun terlihat bahwa curah hujan tertinggi diperoleh pada bulan Januari sebesar 249,6 mm/bulan, sedangkan curah hujan terendah diperoleh pada bulan September yaitu sebesar 66,5 mm/bulan. Nilai evapotranspirasi potensial (ETc) rata-rata di lahan kebun sawit adalah 129,96 mm, sedangkan evapotranspirasi aktual (ETA) adalah sebesar 174,23 mm. Nilai kandungan air tanah (KAT) rata-rata sebesar 66,68 mm dengan surplus air sebesar 14,06 mm. Nilai evapotranspirasi potensial (ETc) rata-rata di lahan hutan konversi (karet) sebesar 122,97 mm, sedangkan evapotranspirasi aktual (ETA) sebesar 174,23 mm. Nilai kandungan air tanah (KAT) rata-rata sebesar 66,68 mm, dengan rata-rata surplus air sebesar 21,05 mm. Terdapat perbedaan antara lahan hutan konversi dengan lahan yang sudah dikonversi menjadi perkebunan kelapa sawit. Perubahan ini menyebabkan penurunan nilai surplus air yang ada sekitar 9 mm per tahun dengan perhitungan nilai surplus pada hutan konversi sebesar 1.569 mm per tahun menjadi 1.560 mm per tahun pada lahan perkebunan. Penurunan ini akan berakibat pengurangan pada debit air yang berakibat pengurangan nilai air tersedia yang mampu dimanfaatkan oleh stakeholder pengguna air, dan salah satunya adalah sektor domestik. This study aims to assess the potential evaporation value (Etc) of oil palm and conversion forest plantations using the water balance change model according to Mather (1957) and Blaney-Criddle on oil palm plantations with conversion forest land. The research location is PTPN IX Lake Salak, Astambul District, Banjar Regency. The results showed that the probability of rainfall being exceeded by 75% for 10 years showed that the highest rainfall was obtained in January of 249.6 mm/month, while the lowest rainfall was obtained in September of 66.5 mm/month. The average potential evapotranspiration (ETc) in oil palm plantations is 129.96 mm, while the actual evapotranspiration (ETA) is 174.23 mm. The average value of soil water content (KAT) is 66.68 mm with a surplus of 14.06 mm. The average potential evapotranspiration (ETc) in conversion forest land (rubber) is 122.97 mm, while the actual evapotranspiration (ETA) is 174.23 mm. The average value of soil water content (KAT) is 66.68 mm, with an average surplus of 21.05 mm. There is a difference between conversion forest land and land that has been converted to oil palm plantations. This change causes a decrease in the value of the existing surplus of water by about 9 mm per year with the calculation of the surplus-value in conversion forests from 1,569 mm per year to 1,560 mm per year on plantation land. This decrease will result in a reduction in water discharge which results in a reduction in the value of available water that can be utilized by water user stakeholders, and one of them is the domestic sector.

Climbing perch enlargement activities are constrained by available fry, due to insufficient production. One of the unknown aquaculture factors is the best water level that can be used in spawning activities for climbing perch. The purpose of the study was to determine the effect of water level manipulation on the spawning results of climbing perch carried out naturally. The study used 3 treatments, namely water levels of 40 cm, 50 cm, and 60 cm and each treatment was repeated 4 times, while the parameters observed included fecundity, egg diameter, fertilization rete, hatching rate, survival rate, and water quality. The results showed that fecundity, egg diameter, fertilization rate, the highest hatching rate were obtained at treatment B of 26419.50 eggs, 0.63 mm, 59.50%, and 41.25%, respectively, while the highest survival rate was obtained in treatment A, which was 71.00%. Water quality during the study was still at the tolerance limit that supports the spawning of climbing perch, namely temperatures between 25.2 – 26.2oC, pH between 7.05 – 7.34, and DO between 3.77 – 4.21 mg / L. Based on diversity analysis (ANOVA) it shows that Fhitung < Ftabel is stated to be no real difference between all treatments given (receive H0) and the results of regression tests show that a water level of 45 cm is optimal for natural spawning of climbing perch Kegiatan pembesaran ikan papuyu terkendala dengan benih yang tersedia, karena produksinya yang tidak mencukupi. Salah satu faktor budidaya perairan yang belum diketahui adalah ketinggian air yang terbaik yang dapat digunakan dalam kegiatan pemijahan ikan papuyu. Tujuan penelitian untuk mengetahui pengaruh manipulasi ketinggian air terhadap hasil pemijahan ikan papuyu yang dilakukan secara alamiah. Penelitian menggunakan 3 perlakuan, yakni ketinggian air 40 cm, 50 cm, dan 60 cm serta masing-masing perlakuan diulang sebanyak 4 kali, sedangkan parameter yang diamati meliputi fekunditas, diameter telur, derajat pembuahan, derajat penetasan, survival rate, dan kualitas air. Hasil penelitian menunjukkan bahwa fekunditas, diameter telur, derajat pembuahan, derajat penetasan tertinggi diperoleh pada perlakuan B masing-masing 26419,50 butir, 0,63 mm, 59,50%, dan 41,25%, sedangkan survival rate tertinggi diperoleh pada perlakuan A, yakni 71,00%. Kualitas air selama penelitian masih berada pada batas toleransi yang menunjang pemijahan ikan papuyu yaitu suhu antara 25,2 – 26,20C, pH antara 7,05 – 7,34, dan DO antara 3,77 – 4,21 mg/L.
