Abstract

Overfishing makes the population of gonggong conch even smaller in their habitat. Its preservation can be maintained by cultivating gonggong conch, including by preparing mature gonads through induction using gonadotropim hormone. This study aims to obtain an effective type of hormone treatment in accelerating the maturation process of the gonggong conch gonads. This research was conducted in April - July 2020 at the Laboratory of the Faculty of Maritime Science and Fisheries, Raja Ali Haji Maritime University, Tanjungpinang, Kepri Province. The method used is a completely randomized design (CRD) with 4 treatments and 3 replications, injection treatment NaCl 0,5µL/head (K), injection treatment oodev® 0,5µL/head (PA), injection treatment PG600® 0,5µL/head (PB), injection treatment oodev® 0,25 µL + PG600® 0,25 µL/head (PC). The results showed that the highest GSI value is PC treatment (0.12±0.36%). Effective treatment in accelerating the process of maturing of gonggong conch gonads is a PC treatment because it reaches TKG II through the histology result ogf gonad. The highest absolute weight growth of the gonggong conch was the PC treatment (0.07±0.01 g). The highest growth length of the gonggong conch was the PC treatment (0.83±0.23cm).

Abstract

This study aims to determine the dosage of different papain enzymes in trash feed to increase the survival and seed growth of Napoleon Cheilinus undulates fish. This research was conducted in December 2019 - January 2020 at the Napoleon fish rearing location in Kiabu Village, South Siantan, Anambas Islands Regency. The method used was experimental with a completely randomized design (CRD) with 4 treatments and 3 replications. Where K: without the enzyme, A: 6% the enzyme papain, B 7% the enzyme papain, C: 9% the enzyme papain. Data analysis using One-Way ANOVA and Duncan's Test. Showed the best growth was obtained in treatment C (administration of 9% papain enzyme) with the results of absolute weight growth of ((0.329 ± 0.020g) and survival (100 ± 0.00%) The results showed that 9% C treatment was the best treatment for growth.

Abstract

This research was carried out on April - June 2021 at the Pengujan Fish Seed Center, Teluk Bintan Districts, Bintan Regency. The purpose of this study was to determine the best percentage of water change for the survival rate of barramundi larvae. This research was conducted using a Completely Randomized Design method (CRD) with 4 treatments and 3 replications consisting of: (1) K (without water change), (2) A (20% water change), (3) B (25% water change) and (4) C (30% water change). The results showed that the optimal percentages of water change was treatments A with a larval survival rate of 19,87±1,00% and a larval absolute length growth of 0,23±0,03 mm.

Abstract

This study aims to determine the optimal temperature range of rearing media for the growth and survival of barramundi larvae. This research was conducted in the biology laboratory of the Faculty of Marine Sciences and Fisheries, Raja Ali Haji Maritime University. The test fish used were 3 day old white snapper larvae which were kept in 13 aquariums where one aquarium was specifically for organ observation. The aquarium used is 25x25x35 cm filled with 10 liters of water with a density of 5 fish/liter. The temperature treatments were P1 (26°C), P2 (28°C), control (30°C), and P4 (32°C) with 3 replications. The design used was a completely randomized design. Larvae were fed rotifers using the abliditum method with a frequency of 3 times a day. The results showed that the white snapper larvae produced a length growth rate and survival rate of 4.99 mm and 28,67 % at an optimal temperature of 32°C.

Abstract

Ikan kerapu cantang (Epinephelus fuscoguttatus x Epinephelus lanceolatus) di Indonesia sedang dikembangkan dan digalakkan sebagai komoditas budidaya laut unggulan untuk diekspor dengan nilai yang cukup tinggi. Harga ikan kerapu berkisar antara Rp. 110.000- 120.000/kilogram. Pembudidaya umumnya memberikan pakan pada ikan budidaya hanya menurut kebiasaannya, tanpa mengetahui tentang kebutuhan. Salah satu usaha yang dapat dilakukan dalam usaha budidaya untuk mendukung tingkat keberhasilan budidaya salah satunya dengan cara pengaturan frekuensi pemberian pakan. Sehingga perlu dilakukan penelitian lebih lanjut tentang frekuensi yang tepat untuk dapat mengoptimalkan pertumbuhan ikan kerapu cantang. Penelitian ini dilaksanakan pada bulan Oktober -November 2020 di Kelompok Budidaya Maju Mandiri, Kelurahan Kampung Bugis, Kota Tanjungpinang, Kepulauan Riau. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan yaitu A : 1 kali/hari, B : 2 kali/hari, C : 3 kali /hari, D : 4 kali/hari. Analisis data menggunakan One-Way ANOVA dan uji lanjut Duncan. Hasil analisis data menunjukan bahwa nilai FCR, EP, BM, PM, SGR terbaik terjadi pada perlakuan D dengan nilai FCR (2,25±0,02), EP (44,49±0,36 %), BM (26,8±0,28 g), PM (5,0±0,35 cm), SGR (0,638±0,006g/hari).
