Abstract

Glofish Tetra (Gymnocorymbus ternetzi) is a transgenic product of tetra fish in which a fluorescent gene from jellyfish is inserted into the fish egg genome, resulting in heritable expression of fluorescent protein. Currently, glofish is one of the most sought-after ornamental fish commodities, so it has high economic potential in the cultivation sector. The success of ornamental fish cultivation is influenced by the quality and type of feed given from the larval to broodstock phase. This study aims to determine the effect of providing different types and combinations of natural feed on the growth and survival of glofish tetra larvae. This research was conducted for 40 days in May - July 2025, located at the Fish Breeding and Cultivation Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau, Pekanbaru. The method used in this study was an experimental method using a one-factor Completely Randomized Design (CRD) with 4 treatment levels and 3 repetitions. The larvae used in the study were 7 days old and underwent feed adaptation for 2 days from the results of natural spawning carried out at the Fish Spawning and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. Feeding is done with a frequency of three times a day, namely at 08.00, 12.00, and 17.00 WIB, and is given to the larvae using the ad-satiation method. The parameters measured in this study were absolute length and absolute weight growth, larval growth rate, larval survival, larval response to feed and water quality. The results of the analysis of variance (ANOVA) test showed that providing different types and combinations of natural feed had a significant effect (P<0.05) on absolute length growth, absolute weight growth, specific growth rate and survival of glofish tetra larvae. The best treatment was P2 (AR2T4) with an absolute length of 2.34±0,01cd cm and an absolute body weight of 0.4409±0,0070c g, a specific growth rate of 2.85±0,025d %, and a survival rate of 95,00±1,67b %. The water quality in this study was classified as optimal, with temperatures ranging from 25.9 to 27.1 °C, pH 6.3 to 6.4, and DO 5.43 to 6.58 mg/L.

Abstract

Ketapang (Terminalia catappa) leaf solution plays an important role in water quality and the growth of catfish. This research was conducted in May 2023 at the Environmental Quality Laboratory of Aquaculture, Faculty of Fisheries and Marine Sciences, Universitas Riau. This study aims to determine the effect and get the best dose of ketapang leaf solution on the physics parameters of water growth media for catfish. This study used a completely randomized design (CRD) method with four treatments and three replicates, the size of the fish used in this study was 4-6 cm. The results of the research that has been done are the provision of ketapang leaf solution gives an influence on the concentration of pH, growth, and survival rate. The best treatments was obtained in P2 (4 g/L) with pH value (7.19±0.04), absolute length (0.93 cm), absolute weight (1.47 g), and survival rate (96.67%).

Abstract

The coastal waters of Indonesia are extensive, and one of the areas is the Mentawai Islands Regency. The Mentawai Islands are a distribution area for several types of turtles, including the leatherback turtle, green turtle, hawksbill turtle, and olive ridley turtle (Lepidochelys olivacea). The study focuses on the morphometric characteristics of olive ridley turtle hatchlings. Olive ridley turtles found in the Buggei Siata Turtle Conservation Area do not have complete morphometric data, so an observation of the morphometric characteristics of olive ridley hatchlings in this area was conducted. This study aims to determine the morphometric characteristics of olive ridley hatchlings and to complete the data for turtle conservation in Buggei Siata, Betumonga. The research was carried out from December 2021 to March 2022 at Buggei Siata Beach, Betumonga. The data analysis used ANOVA followed by Tukey's post-hoc test with 5 different nests and a total sample size of 35 hatchlings per nest. The results of the morphometric characteristics are as follows: carapace length (CL) ranged from 37.93 to 43.56 mm, carapace width (CW) from 28.36 to 36.35 mm, neck length (NL) from 10.08 to 14.21 mm, head width (HW) from 12.03 to 15.34 mm, front limb length (FLL) from 31.06 to 39.74 mm, plastron width (PW) from 19.74 to 29.85 mm, and weight from 13 to 18 grams. Significant differences were found between nests (p<0.05) in these measurements, while for head length (HL) from 16.98 to 19.91 mm, head height (HH) from 10.73 to 13.93 mm, rear limb length (RLL) from 11.37 to 21.88 mm, and plastron length (PL) from 23.86 to 37.21 mm, no significant differences were observed between nests (p>0.05). Based on the data, there are differences in the morphometric size of olive ridley hatchlings among the observed nests
