Lama Waktu Tingkat Kematangan Gonad Udang Vanamei melalui Ablasi dan Non-Ablasi
No full textPenelitian ini dilakukan untuk melihat perbedaan lama waktu pematangan gonad dari udang vaname yang di ablasi dan tidak di ablasi. Penelitian ini dilaksanakan di instalasi Pembenihan Udang di Balai Perikanan Budidaya Air Payau (BPBAP) Situbondo, Jawa Timur. Karakteristik induk udang yang baik adalah udang jantan dan betina memiliki karakteristik reproduksi yang sangat bagus. Spermatofora jantan berkembang baik dan berwarna putih mutiara dan udang betina matang secara seksual dan menunjukkan perkembangan ovarium yang alami. Induk berasal hasil pemuliaan Multipication Broodstock Center (MBC) dengan bobot tubuh sebesar 30-35 g (jantan) dan 40-45 g (betina). Induk diberikan kombinasi tiga jenis pakan selama masa pemeliharaan dengan frekuensi pemberian 4 kali sehari sebesar 40% dari biomassa yakni pukul 07.00, 11.00, 15.00 dan 19.00. Proses ablasi dilakukan pada pagi hari. Proses ablasi yang dilakukan adalah dengan cara memegang induk betina secara perlahan-lahan dan hati-hati sehingga udang tidak merontaronta dengan cara melipat ekor udang ke arah dalam secara perlahan. Lalu setelah itu dilakukan pemotongan tangkai mata menggunakan gunting arteri yang telah dipanaskan. Pemotongan tangkai mata dapat dilakukan pada bagian kanan ataupun kiri sesuai kondisi mata induk. Setelah di ablasi, induk udang diamati tingkat kematian untuk meyakinkan ketersediaan induk yang akan digunakan untuk pengamatan tingkat kematangan gonad. Tingkat kematangan gonad udang vaname menunjukkan ada perbedaan pada lama hari inkubasi untuk perlakuan ablasi dan non-ablasi. Periode waktu untuk perkembangan TKG udang yang di ablasi antara 0-12 hari sedangkan 0-22 hari untuk yang tidak di ablasi.This study was conducted to see the time difference in the gonad maturation time period of ablated and non-ablated Vaname shrimp. This study was conducted at the Shrimp Hatchery Instalansi at the Brackish Water Aquaculture Center (BPBAP) Situbondo, East Java. The broodstock originated from the Multipication Broodstock Center (MBC), where they were bred for body weights of 30-35 g for males and 40-45 g for females. During the rearing period, the broodstock received a combination of three types of feed four times a day at 40% of biomass, at 07:00, 11:00, 15:00, and 19:00. We carried out the ablation process in the morning. We perform the ablation process by gently folding the shrimp's tail inward and holding the female parent slowly and carefully to prevent it from struggling. Next, use heated artery scissors to cut the eye stalk. Depending on the condition of the parent's eye, you can cut the eye stalk on either the right or left side. We observed the mortality of shrimp broodstock after ablation to ensure its availability for gonadal maturity observations. The difference in the number of days needed for ablation and non-ablation treatments was seen in the vanamei shrimp's gonadal maturity level. The time period for the development of TKG in ablated shrimp is between 0 and 12 days, while 0 and 22 days for non-ablated shrimp

Tujuan penelitian ini adalah mengevaluasi suplementasi L-karnitin dan tepung kayu manis terhadap kadar lemak dan tekstur daging ikan patin pada fase pembesaran. Ikan patin berukuran 125,4 ± 7,85 g dan panjang 24,71±0,68 cm dipelihara selama 60 hari dalam wadah hapa berukuran 2 x 1 x 1 m3. Ikan diberi pakan tiga kali sehari ad satiation dengan perlakuan, sebagai berikut: kontrol (K), penambahan L-karnitin 1 g kg-1 (LK 1), L-karnitin 2 g kg-1 (LK 2), kayu manis 5 g kg-1 (KM 5), dan kayu manis 10 g kg-1 (KM 10). Sampel diambil pada awal, pertengahan, dan akhir pemeliharaan untuk pengukuran kadar lemak daging. Parameter yang diamati yaitu lemak daging dan tekstur daging. Hasil menunjukkan bahwa pemberian KM 10 menghasilkan kadar lemak yang lebih rendah dari perlakuan lainnya setelah 30 hari dan penurunan yang lebih besar yaitu berkisar 51,06% dan 42,55% pada perlakuan LK 2 dan KM 10 pada hari ke-60. Nilai indeks hepatosomatik juga menurun yang diikuti oleh penurunan kadar lemak hati. Nilai kekerasan daging menunjukkan peningkatan kualitas yang terlihat dari nilai yang semakin rendah. Pemberian tepung kayu manis 10 g kg-1 pada fase pembesaran menunjukkan hasil terbaik pada pemberian selama 60 hari dalam menurunkan lemak daging ikan patin hingga memenuhi standar filet, karena adanya proses lipolisis serta pemanfaatan lemak menjadi energi. Kayu manis ini menjadi sangat potensial untuk dikembangkan sebagai feed additive dalam upaya memperbaiki kualitas daging ikan patin fase pembesaran.Striped catfish meat has a high-fat content which is undesirable to markets and customers alike and needs to be reduced. This study aims to evaluate the effect of dietary L-carnitine and cinnamon powder on reducing the fat content of striped catfish meat in the grow-out stage. Striped catfish measuring 125.4 ± 7.85 g and 24.71 ± 0.68 cm body length were kept for 60 days in a hapa with size 2 x 1 x 1 m3. Thefish were fed three times a day at satiation with the following treatments: control (K), the addition of L-carnitine 1 g kg-1 (LK 1), L-carnitine 2 g kg-1 (LK 2), cinnamon 5 g kg-1 (KM 5) and cinnamon 10 g kg-1 (KM 10). Sampling was conducted on the initial, middle and final day for meat fat content analysis. The parameters observed were meat fat and meat texture. The results showed that dietary KM 10 significantly reduced meat fat content compared to controls on the 30th and it showed a more significant reduction, namely 51.06% and 42.55%, in the treatment LK 2 and KM 10 after 60 days treatment. The hepatosomatic index value also decreased, followed by decreased liver fat levels. The lower values of meat hardness imply an increase in meat quality. It can be concluded that the application of dietary cinnamon powder at 10 g kg-1 (KM 10) is the best level to reduce the fat content of striped catfish meat in meeting the fillet standards. This cinnamon has excellent potential to be developed as a feed additive to improve the quality of striped catfish meat in the rearing phase
