    Abstract In this study, we aimed to isolate, identify and characterize lactic acid bacteria (LAB) from the intestine of juvenile seabass (Lates calcarifer) as a new potential probiotic. Four strains of LABs were isolated from the intestines of ten healthy seabass juveniles. In the in vitro screening process using spot lawn assay, one isolate labeled as LAB3 showed inhibitory activity against Vibrio harveyi (ATCC 35,084). Strain LAB3 was determined to belong to the gram positive bacteria group with cocci shape and was identified as Enterococcus hirae using 16S rDNA analysis. This bacterium was able to grow at pH ranging from pH 2 to 10 with the best growth at pH 7. This strain was also able to grow at 0-4% NaCl after 24 h incubation and grew best at 1.5% NaCl. Enterococcus hirae strain LAB3 of the present study is worthy to be further characterized as a potential probiotic for use in seabass culture.

    Abstract Tilapia is one of the most common fish species that is intensively produced all over the world. However, significant measures at improving aquaculture health must be taken since disease outbreaks are often encountered in the rapidly developing aquaculture industry.

    Abstract Epinephelus fuscoguttatus (Forsskål), or brown‐marbled grouper, is a favoured species among aquaculture farmers for its relative easy management and high commercial value. Disease outbreaks, however, negatively impact farmers' livelihoods by reducing fish harvest yields. Traditional selective breeding of disease‐resistant strains is still being practised due to limitations in vaccines and effective antibiotics. Development of biomarkers and molecular quantitative techniques has potential to advance approaches in handling outbreaks of disease. This study aimed to determine selected proteins' expression patterns and suitability as infection‐resistant markers in brown‐marbled grouper. Experimental infection of brown‐marbled grouper with Vibrio parahaemolyticus was established. Fingerlings (N = 70) were acclimatized and maintained in saltwater at 28 ± 2°C, pH 7.9 ± 1, salinity 29 ± 1 ppt and dissolved oxygen 5 ppm. V. parahaemolyticus at 5 × 10¹¹ CFU/ml was injected into the dorsal area of the fish and monitored for 7 days. Expressions of alpha‐2‐macroglobulin, nattectin and parvalbumin were determined in liver, spleen, and blood cells by quantitative PCR. Alpha‐2‐macroglobulin in plasma was detected by western blot immunoassay. Clinical signs of infection included skin haemorrhagic lesions and depigmentation. Susceptible and resistant fish were differentiated by lesions >5 cm and absence of lesion at injection site, respectively. Infection significantly increased expression of alpha‐2‐macroglobulin, nattectin and parvalbumin in the liver and spleen but not in blood cell samples. Levels of alpha‐2‐macroglobulin and parvalbumin were significantly increased in liver of susceptible grouper, whereas alpha‐2‐macroglobulin significantly increased in plasma of resistant fish. In conclusion, alpha‐2‐macroglobulin is a potential infection‐resistant biomarker in brown‐marbled grouper and readily detected in fish plasma.

    Abstract This study was designed to profile the metabolites of Isochrysis galbana, an indigenous and less explored microalgae species. ¹H Nuclear Magnetic Resonance (NMR) spectroscopy and Liquid Chromatography-Mass Spectrometry (LCMS) were used to establish the metabolite profiles of five different extracts of this microalga, which are hexane (Hex), ethyl acetate (EtOAc), absolute ethanol (EtOH), EtOH:water 1:1 (AqE), and 100% water (Aq). Partial least square discriminant analysis (PLS–DA) of the generated profiles revealed that EtOAc and Aq extracts contain a diverse range of metabolites as compared to the other extracts with a total of twenty-one metabolites, comprising carotenoids, polyunsaturated fatty acids, and amino acids, that were putatively identified from the NMR spectra. Meanwhile, thirty-two metabolites were successfully annotated from the LCMS/MS data, ten of which (palmitic acid, oleic acid, α-linolenic acid, arachidic acid, cholesterol, DHA, DPA, fucoxanthin, astaxanthin, and pheophytin) were similar to those present in the NMR profile. Another eleven glycerophospholipids were discovered using MS/MS-based molecular network (MN) platform. The results of this study, besides providing a better understanding of I.galbana’s chemical make-up, will be of importance in exploring this species potential as a feed ingredient in the aquaculture industry.
