Abstract

The production of cryopreserved sperm giant grouper has been successfully carried outto support produced hybrid grouper in Indonesia. Thawing cryopreserved sperm is oneof key to successfully insemination. However, research on the effect of thawing timeof cryopreserved sperm giant grouper (E. lancolatus) on motility rate and viability ratehas not been conducted. This research aims to determine the effect of different durationthawing of cryopreserved sperm giant grouper (E. lanceolatus) on motility rate andviability rate. This research was conducted in December 2020 at Batam MarineAquaculture Fisheries Center, Batam City, Kepulauan Riau Province. The method usedwas experimental completely randomized design (CRD) with 4 treatments and 3replications, namely 3 seconds, 9 seconds, 15 seconds, 21 seconds. Data analysis usedANOVA and Duncan’s continued test showed that the best motility happened in 21seconds (69,99±4,74), the best sperm viability happened in 21 seconds (54,29±1,76).The results obtained indicate that 21 seconds is the best treatment.

Abstract

This study aimed to gain rGH dose for the growth of Asian Seabass This research was conducted from July to September 2020 in Madong Village, Tanjungpinang City, Riau Islands Province. The method used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely K: without rGH, A: 10 mg rGH / kg of feed, B: 12 ​​mg of rGH / kg of feed and C: 14 mg of rGH / kg of feed. The results of the absolute weight parameter study showed the values ​​of K (24.79 ± 3.13 g), A (23.87 ± 1.91 g), B (42.01 ± 1.87 g) and C (41.93 ± 0.99 g). The daily growth rate parameters indicated the values ​​of K (0.59 ± 0.07 g), A (0.57 ± 0.05 g), B (1.00 ± 0.04 g) and C (1.00 ± 0.02 g). This study concludes that the rGH affects the growth of Asian Seabass seed. It can be seen from the best treatment namely the treatment with a dose of rGH 12 mg/kg of feed with an absolute weight parameter value of 42.01 ± 1.87 g and a daily growth rate of 1.00 ± 0.04 g / day.

Abstract

This research is about the growth rate of green and brown Kappaphycus alvarezii seaweed in different cultivation methods. This study aims to compare the growth of Kappaphycus alvarezii green and brown varieties and determine the appropriate cultivation method for waters in the Riau Islands. This research was conducted from 27 May 2021 to 11 July 2021 for 45 days in Berakit Village, Teluk Sebong District, Bintan Regency, Riau Islands Province. In this study, there were two variations, namely the green variety and the brown variety with a Randomized Block Design (RAK) with each variation having 3 treatments and 3 replications. The parameters measured were absolute weight growth, specific growth rate, survival and water quality. Data analysis used a two-way ANOVA test of variance and continued with the Tukey test. The results showed that the highest seaweed growth was found in green varieties with the best cultivation method being floating rafts.
