Abstract

Interest in the cultivation of koi carp commodities has increased during the Covid-19 pandemic. Breeders come from various communities. This study aims to determine whether topographic differences have an effect or not on the growth of koi carp. The research was conducted from February to March 2022 for 45 days. The location of the research was carried out in three different places, Kaliangkrik, Tempuran, and Kebumen. The research method used was a Completely Randomized Design (CRD) with 3 treatments and 3 repetitions. The first treatment is an altitude of 1,030 meters above sea level (Kaliangkrik), the second is 323 meters above sea level (Tempuran), and the third is 26 meters above sea level (Kebumen). The data were analyzed using the Analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) further tests. The results showed that topographic differences affect the growth of koi fish both in weight and length growth of koi fish. The altitude that produces the best growth in this study is at an altitude of 26 meters above sea level or located in Kebumen. This is supported by the data showing the highest weight (average 4,1 g), the longest (average 2.5 cm), the lowest FCR (average 2,16), and the highest Survival Rate (SR) high (80%).

Abstract

Graphical Abstract   Highlight Research The Linf CL value in male karumba was 44.21 mm and female was 42.8 mm, with negative allometric growth. The theoretical maximum lifespan (Tmax) of individual karumba, estimated using the VBGF, was 4 to 6 years. The growth coefficient (K) K. karumba is considered quite slow between 0.5-0.9 per year. The exploitation value of karumba is considered vulnerable at this time so that there is a need for management in terms of capture. The results show that recruitment occurs almost every month. Estimated peak recruitment of karumba is around November and January.     Abstract This study provides the first information on the population parameters of Karumballichirus karumba. A total of 902 K. karumba samples were collected, consisted of 412 males and 490 females. The von Bertalanffy parameters were estimated to have asymptotic length L∞ (mm): male = 44.21, female = 42.8, and pooled = 44, negative allometric condition factor, growth rate K (/years): male = 0.58, female = 0.67, and pooled = 0.9. Growth performance index (ϕ') : male = 3.05, female = 3.08, and pooled = 3.24. The natural mortality rate M (/years): male =0.7, female = 0.8, and pooled = 1, and shrimp mortality rate F (/years): male = 1.57, female = 2.89, and pooled = 3.12. The current exploitation rate is slightly higher than optimal exploitation rate = 0.5, indicating that there is a need to regulate fishing so that it is sustainable. The size of the first time caught is still below (1/2 Linf); thus, the reproductive opportunities of K. karumba are guaranteed, and in terms of utilization, fall into the category of sustainable fishing. The estimated life span of K. karumba is 4 to 6 years. Reproduction occurs continuously every month, indicated by the discovery of ovigerous females. The highest recruitment occurs in January and November. YPR (yield-per-recruitment) shows that the value of Fcur = 3.12 years⁻¹ in the estimated population is lower than Fmax = 5 years⁻¹ and above F05 = 1.99 years⁻¹ and F01 = 1.8 years⁻¹.
