Abstract

The background of this research is that vertiqua is considered to have high production costs and small profits. Therefore, a business analysis is needed to increase the effectiveness of the fish farming business using the vertiqua system. The purpose of this study is to analyze the aquaculture business using the vertiqua system including capital and profit obtained. This research uses qualitative methods with descriptive explanations. The results of the research that has been done show that the R / C Ratio value obtained is 1.66, meaning that every 1 cycle cost expenditure will get 1.66 revenue. Koi fish farming using the vertiqua system is said to be feasible to continue because the R / C Ratio value is 1. The JWPM value with the calculation of 8 cycles for 1 year is 1.4, meaning that it takes 2 months and 2 days for the capital to return. Based on the business analysis conducted, the production of koi fish seeds using the upper biofical filter vertiqua system can be said to be feasible and has the potential to be further developed, because it can provide good profits with a good JWPM. In addition, cultivation using the upper biofical filter vertiqua system is very efficient in providing care for koi fish cultivation.

Abstract

Rainwater is often considered to have a negative impact on the survival of fish fry, mainly due to its slightly acidic pH. However, this study aims to investigate the effect of rainwater on the survival rate of comet fish fry (Carassius auratus). The research was conducted at the Bossbaster experimental pond, Legok Nyenang Village, Kadudampit District, Sukabumi Regency, over a period of three days. The fish fry used were one day old after hatching, with a size of approximately 5 mm. The study utilized 15 containers with a water volume of 10 liters per gallon and 15 aeration devices to maintain water circulation. Five treatments were tested: A (100% rainwater), B (75% rainwater), C (50% rainwater), D (25% rainwater), and E (0% rainwater). The research design followed a Randomized Complete Block Design (RCBD) with three replications for each treatment. The data were analyzed using the Median Test and Regression Test to maximize the obtained results. The results showed that rainwater did not significantly affect the survival rate of comet fish fry. The survival rate of the fry in all treatments ranged from 98.33% to 99.17%. This indicates that although rainwater has a lower pH, it does not significantly affect the survival of comet fish fry. Based on these findings, it can be concluded that the rainwater taken from the research site did not negatively impact the survival rate of comet fish fry. The quality of the rainwater used in this study is safe and can be used as a medium for raising fish fry without causing a decrease in their survival rate. This study provides valuable information on the use of rainwater in fish farming, especially for comet fish fry.

Abstract

This study was conducted to analyze the effect of rainwater on the survival of koi fry. The background of this study is based on the increasing demand for koi fish which encourages breeders to improve the quality and quantity of fry production. However, the success of seeding is influenced by several factors, especially air quality such as temperature and pH. Rainwater is known to have less stable quality, especially due to its low pH value, so it is necessary to study its impact on koi fry. This study was conducted on November 25–28, 2024 in the Bossbaster experimental pond, Legok Nyenang Village, Kadudampit District, Sukabumi Regency. The media used were 15 plastic gallons, each containing 5 liters of air and 40 newly hatched koi fry. The experimental design used a Completely Randomized Design (CRD) with 5 treatment levels and 3 replications. Treatments included A (100% rainwater), B (75% rainwater + 25% well water), C (50% rainwater + 50% well water), D (25% rainwater + 75% well water), and E (100% well water). The results of the ANOVA test showed that there was no significant difference (P>0.05) in the survival value of koi fish fry in the five treatments. Thus, it can be concluded that the use of rainwater does not have a significant effect on the survival of koi fish fry. In addition, the results of water quality observations showed that all parameters were still within the standard quality range, except for the temperature which was slightly below the standard.
