Effects of Antimicrobial Peptides Surfactin Administration on Growth Performance, Intestinal Digestive Enzymes Activities and Some Serum Biochemical Parameters of Orange-spotted Grouper (Epinephelus coioides) JuvenilesShao
Get PDFThis trial was conducted to investigate the effects of dietary surfactin supplementation on the growth performance, intestinal digestive enzyme activities, and some serum biochemical parameters of orange-spotted grouper (Epinephelus coioides) juveniles. Three hundred and sixty fish were randomly divided into six treatment groups with four replicates in each group and 15 fish in each replicate. The dietary surfactin levels of four treatment groups were 0 (control group), 25, 50, 100, 150, and 200 mg/kg, respectively. The trial period was 8 weeks. Compared with the control group, final body weight, weight gain rate, and feed conversion ratio were improved significantly by 100mg/kg surfactin supplementation (P0.05). Protease and lipase activity in intestine of 50, 100, and 150 mg/kg surfactin supplementation groups were significantly higher than those of the control group (P0.05). The blood urea nitrogen levels, and acid phosphatase and alkaline phosphatase activity in 100, 150, and 200 mg/kg surfactin supplementation groups were significantly ameliorated (P<0.05). The albumin level of 100 mg/kg surfactin supplementation group was significantly higher than that of the control group. Lysozyme activity of 50, 100, and 150 mg/kg surfactin supplementation groups was significantly higher than the control group (P<0.05). In conclusion, we demonstrated a promotion of growth performance and improvement of intestinal digestive enzyme activity, and some serum biochemical parameters of the orange-spotted grouper juveniles by appropriate surfactin levels supplemented in diet

On the r>h Shift in Kiên Giang Khmer
Get PDFThis paper presents an acoustic and perceptual study of the r>h shift in the variety of Khmer spoken in Giồng Riềng district, Kiên Giang province, Vietnam. In Phnom Penh Khmer, /r/ is realized as [h] in syllable onsets and onset clusters, and accompanied by lowered pitch, breathiness, and in some cases a change in the quality of the following vowel. In Kiên Giang Khmer, the r>h shift is accompanied by pitch lowering, but without changes in aspiration or vowel quality, and spectral measures did not indicate substantial differences in voice quality. Consistent with their productions, users of this dialect appear to rely solely on differences pitch to identify these lexical items. We discuss the implications of our findings for Khmer dialectology, mechanisms of sound change, and variation in the realization of rhotics more generally
Differences in Language Used by Deceivers and Truth-Tellers in Thai Online Chat
Get PDFDeception detection, especially in online communication, is a burgeoning area of research, but most previous studies have focused on English. Therefore, in this paper, we investigate the applicability of English deceptive features to Thai and also examine whether there are any Thai-specific features not found in English which are associated with Thai deception in online communication. 96 Thai-language chat dialogues were analyzed with results suggesting that features identified in English deception research cannot be transferred to Thai. Two Thai-specific indicators of deception were also identified. The results have implications for theories of deception detection and for the transfer of research findings between languages
Development of Polyculture and Integrated Multi -Trophic Aquaculture (IMTA) in Israel: A Review
Get PDFIsraeli aquaculture began in the 1920s, with common carp monoculture. This was followed by polyculture of carp with tilapias, grey mullet, and planktivorous carp. Scientific research on polyculture started in the 1950s and has since contributed to the global science and practice of green water aquaculture, especially with novel polyculture approaches and concepts. Today, the industry is characterized by intensive freshwater polyculture, implemented in earthen fish ponds and reservoirs. In the Mediterranean coastal plain, fresh, brackish, and marine water polyculture is carried out in semi-intensive fishponds. Polyculture in Israel is an entrepreneurial activity that combines ecological principles of Chinese polyculture with local technologies and objectives. The Biofloc approach (active suspension ponds, ASP), periphyton, and aquaponics, were developed in the 1980s in response to rising public and policymakers’ concerns and regulations on land use, pollution, use of chemicals, and organic manures. R&D on marine integrated multi-trophic aquaculture (IMTA) systems began in the early 1970s at the National Center for Mariculture (NCM) in Eilat. It started with sea bream and mullet in earthen seawater ponds, whose plankton-rich water recirculated through bivalve and macroalgae biofiltration modules. An advanced form of the concept was deployed in the early 1980s and was studied in detail using nutrient budgets. Several system models with fish, bivalves, and algae, on small and pilot scales, were studied and quantified. Abalone, sea urchins, shrimp, brine shrimp, Salicornia, and periphyton, were added to the Eilat marine IMTA models, beginning in the 1990s. Upon entering the third millennium, Israeli research further examined the relationship between the sustainability and economics of IMTA in world aquaculture
Stenotrophomonas maltophilia: an Emerging Pathogen of Ascites Disease in Farmed Yellow Catfish Pelteobagrus fulvidraco
Get PDFAscites disease causes significant economic losses in yellow catfish Pelteobagrus fulvidraco. Yet only scare information is reported on Stenotrophomonas maltophilia as a pathogen for yellow catfish. In this study, a virulent strain, temporarily named WY1, was isolated from diseased yellow catfish fry suffering from ascites disease, identified phenotypically and molecularly as S. maltophilia. A phylogenetic tree was constructed to examine isolate WY1 and compare it to other known isolates. In addition, isolate WY1 is apparently susceptible to aminoglycosides and tetracycline drugs for veterinary uses in aquaculture as revealed when screened against a range of common antibiotics. To the best of our knowledge, this is the first report of S. maltophilia as a pathogen of ascites disease in farmed yellow catfish
On the Number of Voices in Madurese
Get PDFTwo voices have previously been documented in Madurese: an active voice, and a non-active voice with e- prefixed verbs. In this paper I examine the non-active voice, which has variously been called passive voice or object voice, and demonstrate that it is a canonical passive voice. Furthermore, I document the existence of a distinct third voice, an object voice similar to that of other languages of the area. The object voice is used in the polite register, but not in the familiar register, so the two-voice system in the familiar register differs from the three-voice system in the polite register. The registers are also differentiated by nominal extraction patterns: objects may extract in polite speech, but not in familiar speech. In view of these contrasts, I argue that the familiar and polite registers each operate with distinct sets of morphosyntactic rules, or distinct grammars
