Abstract

This study was aimed to observe the effects of different cryoprotectants in embryo cryopreservation on damage and hatching rates of African catfish (Clarias gariepinus) embryo. The gastrula-staged embryos were treated 5% (v/v) solutions concentration of dimethyl sulfoxide (DMSO), propylene glycol (PG), honey, and combined cryoprotectants, respectively and preserved at temperatures of 4 and 0ºC for 30 min, 1 h, 2 h, 3 h, 4 h, 5 h, and 6 h, respectively. Thawing of embryos was conducted in freshwater at a temperature of 28ºC. Then, the embryos were incubated in the aquaria at 28ºC temperature. The result showed that the different cryoprotectants in gastrula-staged embryo cryopreservation affect damage and hatching rates of African catfish embryos at different length of preservation. The percentage of catfish embryo damage increases with different length of preservation and the storage temperature. A combination of DMSO-honey and PG-honey has the lowest damage percentage and the highest hatching rate of catfish embryo compared to other treatments (p<0.05).

Abstract

Euchema cottoni or Kappaphycus alvarezii is one type of seaweeds that is widely cultivated in Indonesia. Water pollution caused by the accumulation of Pb heavy metals will affect the seaweed to grow and develop. This study is aimed to determine the tannin levels in K. alvarezii and the relationship of Pb heavy metal pollution level with tannin levels in K. alvarezii in different waters. This study used an observational experiment, and samples were taken from two different locations with 4 stations in each. From each sample in both locations, K. alvarezii was taken and was then measured for the tannin levels, water quality, and heavy metals (Pb) in water and in K. alvarezii. The results were analyzed at the Laboratory of PT. Sucofindo and the Laboratory of Testing Service Unit, Airlangga University Surabaya. The data were analyzed using a statistical test in the form of a t-test to determine the differences in samples in both waters, and a C-square test was used to determine the relationship between PB and tannin levels in K. alvarezii. The results showed that the level of Pb heavy metal pollution in the two waters did not show a significant difference due to water quality which was quite similar in both locations. Moreover, the tannin content in K. alvarezii in Bluto waters (0.053±0.004%) was higher than that in Talango waters (0.020±0.009%). Meanwhile, a t-test showed a significant difference in seaweed tannins in both waters. The relationship between Pb heavy metal pollution and tannins of seaweed in Bluto and Talango waters was that they did not affect each other, and tannin concentration was more influenced by chemical oxygen demand (COD), salinity of both waters, and the cultivation methods used.

Abstract

The purpose of this study was to determine the administration of Caulerpa racemosa extract in clinical sign and intestinal histopathological profile of whiteleg shrimp (Litopenaeus vannamei) after infected by Vibrio parahaemolyticus. The study was conducted using a completely randomized design (CRD) with six treatments and three replications. Shrimp were divided into six groups, two control groups without the administration of C. racemosa extract, the other four groups with the administration of C. racemosa extract with successive doses; 30 mg/kg (P1), 60 mg/kg (P2), 120 mg/kg (P3) and 240 mg/kg (P4) through feed. On the 15th day of rearing, the control group was divided into two groups: negative control (K-) was injected with PBS and then positive control (K+) and four other treatments (P1, P2, P3 and P4) were infected with V. parahaemolyticus. The results showed that intestinal damage caused by V. parahaemolyticus infection were inflammation and necrosis. The administration of C. racemosa extract had a significant effect on the histopathological profile of the whiteleg shrimp intestine. The lowest percentage of damage was found in the P4 treatment, which was 19.6% with a indication of low damage. Clinical sigs appeared at 48 hours post-infection pale hepatopancreas, empty intestines, reddened uropods and gnats. From this study, it can be concluded that the administration of C. racemosa extract to the feed at a dose of 240 mg/kg is the best dose in reducing the level of damage to the intestinal organs of whiteleg shrimp infected with V. parahaemolyticus.

Abstract

Shrimp farmers have reported mass mortality of white shrimp (Litopenaeus vannamei), reaching 2-3 kg/day in Gerongan Village, Kraton District, Pasuruan Regency in mid-2021. Preliminary analysis suggests that mass mortality was caused by bacterial diseases. Thus, to find out the main pathogen causing the mass mortality, the present study investigated microbial composition in rearing media of white shrimp (Litopenaeus vannamei) infected by the white feces disease (WFD) and healthy white shrimp using next-generation sequencing (NGS) technology. The research was conducted by collecting normal water samples and infected shrimp pond water samples. The results of the NGS assay showed that Vibrio vulnificus was found dominant in WFD-infected shrimp pond water, therefore was suspected to be the main cause of WFD.
