The landmark-based morphometric and meristic analysis of the kelp grouper (Epinephelus bruneus), red spotted grouper (E. akaara) and seven-banded grouper (E. septemfasciatus) were performed to compare the differentiation of overall body shape and structure. The measurements of the morphometric dimensions were observed in 25 parts (truss dimension: 16 parts; head part dimension: 9 parts) of 38 m...

Lysozyme acts as an innate immunity molecule against pathogen infection. In this study, a new G-type lysozyme gene with a typical G-type lysozyme domain (designated as Ec-lysG) was cloned and characterized from the orange-spotted grouper, Epinephelus coioides. The full-length Ec-lysG cDNA contains 1419 bp and encodes a 256-residue protein containing a 25-residue signal peptide at the N-terminus...

this study was conducted to investigate the effects of curcuma zedoaria and zingiber zerumbet on non-specific immune responses of grouper (epinephelus coioides). fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of c. zedoaria and z. zerumbet mixed diets twice daily for two weeks. non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...

This study was conducted to investigate the effects of Curcuma zedoaria and Zingiber zerumbet on non-specific immune responses of grouper (Epinephelus coioides). Fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of C. zedoaria and Z. zerumbet mixed diets twice daily for two weeks. Non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...

Suppression subtractive hybridization (SSH) was used to generate a subtracted cDNA library enriched with gene transcripts differentially expressed in the spleen of orange-spotted grouper Epinephelus coioides after 5 days of infection with Singapore grouper iridovirus (SGIV). In the forward and reverse-subtracted libraries, 260 and 153 non-redundant expressed sequence tags (EST), respectively, w...

The white grouper (Epinephelus aeneus) is a promising candidate for domestication and aquaculture due to its fast growth, excellent taste, and high market price. A linkage map is an essential framework for mapping quantitative trait loci for economic traits and the study of genome evolution. DNA of a single individual was deep-sequenced, and microsatellite markers were identified in 177 of the ...

This is the peer reviewed version of the following article: Li, S., Monroig, Ó., Navarro, J. C., Yuan, Y., Xu, W., Mai, K., Tocher, D. R. and Ai, Q. (2017), Molecular cloning and functional characterization of a putative Elovl4 gene and its expression in response to dietary fatty acid profiles in orange-spotted grouper Epinephelus coioides. Aquac Res, 48: 537–552, which has been published in fi...

In Taiwan, the mushroom Antrodia camphorata (AC) is used for medicinal purposes, including cancer prevention and treatment. This study aimed to investigate effect of AC-supplemented diets on innate immunity disease resistance orange-spotted grouper Epinephelus coioides against two bacterial infections—Vibrio alginolyticus Streptococcus iniae. Orange-spotted groupers were fed at 0 (control), 1.5...

We investigated the androgenic effects of 17α- methyltestosterone (MT) on gonadal sex reversal in juvenile red spotted grouper Epinephelus akaara. The fish were immersed in 17α-MT at 1 and 5 mg/L. Treatment method of 17α-MT was once weekly for 4 and 8 weeks. Fish were sampled at 12 months after end of the treatment period in order to histological analysis. At the initiation of an experiment (70...
