“…Selain itu, dilakukan pengecekan keberadaan sperma dan perkembangan tingkat kematangan gonad ikan setiap bulan 45,46 . Upaya pemijahan juga dilakukan, baik dengan pemijahan semi alami 47, maupun buatan 48,49 . Hasil pemijahan buatan diperoleh telur yang diovulasikan berdiameter 3,1 ± 0,3 mm, rataan fekunditas 594 butir, derajat pembuahan 30,5%, derajat penetasan 65,5 %, dan sintasan 40% 50 .…”

Domestikasi ikan adalah penjinakan ikan liar melalui penguasaan siklus reproduksi diluar habitat aslinya. Kegiatan domestikasi ikan diawali dengan koleksi, pemilihan populasi yang akan didomestikasikan, pematangan gonad melalui modifikasi lingkungan, pemberian pakan, dan aplikasi hormonal, pendederan serta pembesaran. Permasalahan yang dihadapi dalam domestikasi ikan liar antara lain ketidakmampuan ikan dalam beradaptasi di penangkaran, sulitnya membedakan jenis kelamin jantan dan betina, ikan tidak dapat matang gonad sehingga tidak dapat dipijahkan didalam penangkaran, serta tingginya mortalitas larva pada saat pendederan. Tahapan penting untuk kegiatan domestikasi ikan diawali dengan pemilihan spesies yang tepat melalui pendekatan analisis komoditas sehingga ikan yang sudah terdomestikasi merupakan ikan budidaya baru yang mempunyai nilai ekonomis tinggi dan potensial untuk dikembangkan. Dari rangkain kegiatan yang telah dilakukan, terhadap ikan air tawar dapat di simpulkan pelakanan domestikasi ikan air tawar asli Indonesia dapat dilakukan melalui modifikasi lingkungan mendekati habitat aslinya, pemberian pakan disesuaikan dengan kebutuhan perkembangan gonad, memberikan hormon secara oral yang dicampurkan dalam pakan maupun melalui implant/suntikan. Dalam proses domestikasi analisa genotipe secara molekular maupun fenotipe melalui pengukuran meristik dan morphometrik pada populasi ikan perlu dilakukan untuk memilih populasi dengan variasi genetik yang tinggi. Pada ikan domestikasi secara alami, seperti ikan gurame, untuk meningkatkan produksi perlu dilakukan perbaikan terhadap teknologi budidayanya antara lain dalam pemilihan jenis kelamin induk yang tepat, penggunaan rasio pemijahan yang sesuai, lama penggunaan induk dalam pemijahan dan penanganan larva

“…Fish can be characterized by analyzing their morphology through the truss-morphometric method and their genetics using molecular markers such as random amplifed polymorphic DNA (RAPD) based on PCR [5,6]. Tis study also analyzed condition factors and growth patterns (lengthweight relationships) to determine the characteristics of wader fsh based on their environment.…”

A study on the morphology and genetics of the three species of dominant wader that live in the Progo River has been conducted. This study aimed to identify the three kinds of dominant waders in the Progo River, their morphology, and their genetics to ensure their right identity. Fish characterization was done by morphological analysis using the truss-morphometric method and genetic analysis using molecular markers. Random amplified polymorphic DNA (RAPD) based on PCR was used for diversity identification for interspecies and between species. Several analyses of water quality parameters (temperature, nitrate, phosphate, and ammonia) were also carried out to determine the habitat’s suitability for the fish’s survival. Based on the results of discriminant function analysis, all wader fish from the Progo River used in this study were classified into three species with the highest differentiation character D4 (distance between the starting point of upper tail fin and the starting point of lower tail fin). Results also show that wader abang fish have similar morphometric characteristics and DNA closer to wader kepe compared to wader pari. The length-weight relationship of wader fish from the Progo River shows that the growth pattern of wader abang and wader kepe is allometric positive, while that of wader pari is allometric negative. The value of the condition factor for wader fish from the Progo River indicates that the environmental habitat of wader fish is good and stable so that it can support the fish growth.

Sili (Macrognathus sp.) is one of freshwater fishes that has high economic value in Asia, since it is beneficial as a consumable fish and an ornamental fish. The economic potential of Sili triggers overfishing, especially in East Java. Domestication is a method to preserve Sili in East Java, preceded by identifying potential species of Macrognathus sp. from the natural catchment. This study aims to characterize the morphological differences of Macrognathus sp in several regencies in East Java based on morphological and morphometric phenotypes. Samples were collected at five different locations, specifically: Tulungagung (Boyolangu Watersheds), Kediri (Brantas Watersheds), Mojokerto (Brantas Watersheds), Lamongan (Bengawan Solo Watersheds), and Malang (Karangkates Reservoir). The main parameters observed were morphology and morphometry. The morphological analysis used identification guidelines, while morphometric data were obtained through 14 parameters measurement then analyzed using one-way Anova test on SPSS 25 software. Based on the morphological and morphometric analysis, it is known that the species of Sili in some regencies in East Java are Macrognathus tapirus and Macrognathus aculeatus. The results showed that samples from Tuban and Kediri are Macrognathus tapirus. Furthermore, the samples collected from Mojokerto, Lamongan, and Malang are Macrognathus aculeatus. One-way Anova test showed Sili from the five locations were significantly different based on the result value of p<0.05.
