Abstract

Highlight ResearchWastewater in hybrid grouper culture should be maintain before resirculate and dispose to aquatic environment to avoid eutrophication.Seaweed that is used for biofilter must be observed for its suitability, performance and effectivity.Ulva sp. has the best effectiveness to reduce nutrient in wastewater of hybrid grouper aquaculture by absorbing then stored into thallus.Ulva sp. is proven has the best SGR and adaptability in wastewater of hybrid grouper culture.AbstractWastewater generated from hybrid grouper culture needs to be managed to improve water quality before being recirculated, or discharged in the aquatic environment. Seaweed biofilter has been proposed in wastewater treatment technology for marine fish farming. This study aimed at comparing which of these species i.e. Ulva sp., Sargassum sp., Gelidium sp., and Dictyota sp.  work best to absorb nutrient wastewater hybrid grouper culture. This research utilized these seaweed as treatments and controls with three replications using Completely Randomized Design. A statistical analysis was conducted to investigate the significant differences in the nutrient absorptions among various seaweed species by using ANOVA and least significant difference. Non-parametric tests namely Kruskal-Walis, Mann-Whitney, and t-test were used with confidence interval of 95%. The results revealed that Ulva sp. has the best ability to reduce the Nitrogen 80%, while Dictyota able to reduce  Phosphor 88% by Dictyota sp. generated from wastewater of hybrid grouper culture. While the highest absorbtion of Total Kjeldahl Nitrogen (104%) and phosphate (182%) that stored in thallus were performed by Ulva sp. Ulva sp. had the best performance and highest growth rate (1.9% d-1) as biofilter in hybrid grouper cultivation than other species.

Abstract

Highlight ResearchThe most significant morphological variation was the snout length and caudal peduncleT. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same populationT. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species AbstractHairtails (Trichiurus spp.) are economically important fisheries resources and have become an export commodity. In Indonesia, there are several hairtail species; however, each species distribution is not yet certainly known. This study aimed to identify and determine the morphometric and meristic character of the hairtail from the northern coast of Java, Indonesia. Fish specimens were obtained from fishermen catches in the north coast of Pati and Demak (Central Java) and the northern coast Cirebon (West Java), which captures the fish in less than one-week fishing operation. Fish samples were grouped based on morphological similarities identified in previously published works. After that, 22 morphometric and four meristic characters were measured and counted. Principal Component Analysis and Discriminant Analysis were used to analyze morphometric data, while the meristic data were compared to the available published works. The hairtail caught at the northern coast of Java was long, flat, silvery in color, and had a sagittal crest, with the fin formula being D.III.125-134, P.I.10, and A.I.98-104. According to the morphological and meristic characters, the hairtail caught at Java's northern coast was identified as Trichiurus lepturus. The most significant morphological variation was the snout length and caudal peduncle. The PCA and scattergram analyses showed that T. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same population.  T. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species.

Abstract

  Highlight Research 1. Lymphocystis disease is reported to infect seawater and freshwater fishes 2. The four important freshwater fish species in Indonesia are evaluated on their susceptibility to Lymphocystis Disease Virus 3. Lymphocystis infection causes behavioural changes and mortality with different onset times after infection on the four fish species 4. LCDV load is varied in quantity among different organs. Abstract Lymphocystis disease has a broad host range and has been reported to enter Indonesia. However, information regarding its susceptibility and predilection organs in fish is lacking. This study examined the susceptibility of four important fish species in Indonesia, namely, giant gourami (Osphronemus goramy), hybrid tilapia (Oreochromis sp.), Siamese fighting fish (Betta splendens), and hybrid catfish (Clarias sp.). The fish were infected with virus filtrate by intraperitoneal injection and immersion. The postinfection observation period was 60 days. Viral load was quantified by qPCR and expressed as major capsid protein (MCP) copy number/mg tissue. Mortality was observed in all fish species, with the highest recorded in hybrid catfish and the lowest in Siamese fighting fish. All the fish species showed changes in their clinical symptoms, such as anorexia and separation from schools. However, only giant gourami showed internal change seven days after injection (dpi), with white lesion detected in the liver. Viral load quantification showed that LCDV had different predilection organs in the four fish species. The highest viral load of giant gourami (1.7 x 104) was observed in the liver at 7 dpi, hybrid tilapia (7.5 x 103) was observed in the fins at 21 dpi, Siamese fighting fish (8.4 x 103) was observed in the fins at 14 dpi, and hybrid catfish (1.2 x 103) were observed in the fins and gills at 7 and 14 dpi. The findings indicated that giant gourami, hybrid tilapia, Siamese fighting fish, and hybrid catfish were susceptible to LCDV infection with different predilection organs.
