Abstract

The purpose of this study was to identify chydoridae using conservative way, while the observations of the life cycle was done through a microscope to determine the egg production per parent and length of life. Individual chydoridae acclimatized to reach 10 generations (1 month), and 10 females were isolated for the production of seedlings. Based on literatures review, chydoridae used was derived from subfamily Aloninae (Alona spp.); while studies on the life cycle found: the egg size of chydoridae 150.2 ± 22.4 μm, and neonates have an average size of 291.82 ± 3.06 μm, and reached adult size after 2.3 ± 0.5 days, with an average size of 441.22 ± 10.2 μm. Time of embryonic development occured for 1-2 days. On the entire life cycle, only 2 eggs could be produced per individual. Based on this study, the number of eggs produced by the female during its lifetime ranges between 30-60 eggs. Similarly, the length of life of this organism on average 47.2 ± 11.7 days, with the longest lifespan was achieved 60 days. It was found also the maximum size was 1,037 ± 8.5 mm; while the average size of an organism's body was 800.42 ± 56.3 μm.Keywords: chydoridae, identification, life cycle, Alona spp

Abstract

This study aimed to determine the effect of providing a combination of natural feed maggots and pellets on the growth performance of Nile Tilapia and to ratio between maggots and pellets that promote growth of Nile Tilapia. The research was conducted from June to August 2020. The research method was using a completely randomized design (CRD) with 5 treatments and 3 replications with the following treatments: treatment A = 100% pellets, treatment B = 75% pellets and 25% maggots, treatment C = 50% pellets and 50% maggot, treatment D = 25% pellets and 75% maggot, treatment E = 100% maggot. The test fish used Nile Tilapia fingerling with average weighing 4 g / fish with density of 5 fish / container and maintained for 21 days. The containers used in this study were 15 plastic trays with a diameter of 40 cm and a height of 20 cm each with a water capacity of 15 liters. Growth performance data were Weight gain (WG), Specific growth rate (SGR), relative growth rate (SGR), feed convertion rate (FCR) and feed intake (FI). Based on the results of this study, it shows that the use of a combination of pellet and maggot feed as Nile tilapia juvenile has an effect on the growth performance of Nile tilapia so that maggot can be used as an alternative feed that has high nutritional content for tilapia fish cultivation. The treatment that gave the best growth effect on tilapia seeds was found at the dose of a combination of 50% pellet feed + 50% maggot, with Weight gain (5.5±1.1g), SGR (3.7±0.5%), RGR (139.4±53.4) and FCR (1.2±0.2)

Abstract

This study aimed to examine the effect of adding ciplukan (Physalis angulata) to feed on the growth of tilapia and to find a dose of ciplukan that was able to increase the growth of tilapia (Oreochromis niloticus). The test fish used were tilapia with an average size of 5-8 cm as many as 300 fish from the Center for Freshwater Aquaculture (BPBAT), Talelu. This research was conducted at the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University. This study used a completely randomized design (CRD) with 4 treatments, where each treatment had 3 replications so there were 15 experimental units, the treatment used was ciplukan flour with different concentrations consisting of: A: 0 g flour/kg feed, B : 10 g flour/ kg feed, C : 15 g flour/ kg feed, D : 20 g flour/ kg feed. The data collected consisted of fish weight to measure the fish growth. The results showed that the addition of ciplukan leaf extract in feed with different concentrations gave significantly different effects on the growth of tilapia with treatment B (10 g) showing the highest fish growth reaching 5.24 g, followed by treatment C (15 g) with the highest growth. reached 4.35 g. While the fish treated with D (20 g) only reached 3.16 g in weight where this value was not much different from the growth of fish in control A. Duncan's further test results showed that treatments B, C, D were not significantly different from each other, but these three treatments were very significantly different compared to fish that were not given ciplukan leaf extract. The study showed that ciplukan leaf extract added to feed gave significantly different effects on fish growth, with the best dose of 10 g extract/kg feed. Thus it can be concluded that ciplukan leaf extract can increase growth of Nile tilapia.

Abstract

This study aimed to determine the growth rate and survival of saline tilapia (Oreochromis niloticus) seeds with fed with different types of commercial feed. The study was conducted at the Aquaculture Technology Laboratory in April – July 2021. The experiment was designed using a completely randomized design (CRD) with 4 treatments, each with three replications. The treatments included A: Comfeed brand feed, B: Bintang brand feed, C: Turbo Feed brand feed, D: Supra ZT brand feed. The results of the analysis of variance showed that different commercial feeds had a significant effect on absolute weight growth and specific growth, very significant for absolute length growth, but on survival rates had no significant effect. The results of the BNT test on showed absolute weight growth and specific growth showed of treatment B was not significantly different from treatment A but significantly different from treatments C and D. While for absolute length growth, treatment B was significantly different from treatments D, C, and A. Treatment D, C, and A were not significantly different from each other.

Abstract

This research aimed to determine the growth of snakehead fries t reared in aquaponic media and fed commercial fish food. The treatments consisted of treatment A with a protein content of 40%, B with a protein content of 35%, and C with a protein content of 30%, each with three replications. The research was conducted for 32 days. The research found the absolute growth of treatment a was 1.34 g, treatment b was 0.775 g, and treatment C was 0.605 g. The daily growth rate for treatment a was 4.18%, treatment b 2.42%, and treatment C 1.89%. Linear regression analysis between protein content in food and growth weight of snakehead fish fry had a strong relationship to both absolute growth and specific growth rate. The higher the protein content, the higher the weight growth of snakehead fry. Keywords: snakehead fish, aquaponic, commercial food, protein

Abstract

Several previous studies regarding the use of Moringa leaf flour on fish had been carried out fish consumption including catfish, tilapia, and gourami. The objectives of this research were to determine the effect of substitution of Moringa leaf flour at different doses in feed formulation on the relative growth of tilapia and determine which treatment had the highest feed efficiency value. The results showed relative weight growth value for tilapia were obtained in treatment C (83.82%),  daily growth (C) 2.03%, food conversion ratio (FCR) 1.29, and Feed Efficiency 77.01%. Keywords: relative growth, daily growth, feed conversion ratio, feed efficiency value.
