Five experimental diets were formulated to evaluate the effects of dietary enzymatically hydrolyzed tuna by-product on growth, non-specific immune responses, and hematology juvenile rainbow trout (Oncorhynchus mykiss). A basal diet with 50% fishmeal was used as control (CON) four other replaced 12.5% (TBB12.5), 25% (TBB25), 37.5% (TBB37.5), (TBB50) fish meal in CON diet. Juvenile (4.87 ± 0.05 g) randomly distributed into 15 tanks (50 L) fed 3–4% wet body weight two times a day. At end 7...
Three different dietary additives were evaluated based on growth performance, innate immune responses and disease resistance in juvenile Amur catfish Silurus asotus. Four diets prepared by supplementing 0.4% Song-gang® stone (SG), 0.05% Yucca meal (YM), β-glucan (BG) combination with 0.04% SG BG (SG + BG) to a basal commercial diet (control; CONT). Triplicate groups of fish averaging 4.95 ± 0.05 g fed one the test between 3 5% body weight for 8 weeks. At end feeding trial, gain, specific...
A feeding trial was conducted to determine the optimum level and effect of incremental dietary levels docosahexaenoic acid (DHA, 22:6n-3) on growth non-specific immune responses in juvenile rock bream, Oplegnathus fasciatus. basal diet without DHA supplementation used as a control, six other diets were prepared by supplementing with 4, 8, 12, 16, 20 or 40 g kg−1 DHA. These included no eicosapentaenoic and/or arachidonic contents. The actual concentrations 1, 4.8, 8.9, 13.1, 17.6, 21.2 41.4...
A feeding trial was conducted to evaluate the effects of two different sizes extruded pellets (EP) (EP1 - 3 mm or EP2 5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared semi-recirculation system. total 450 fish with an average initial weight 5.0 ± 0.2 g (mean SD) were fed one three experimental diets triplicate groups. At end 6-week trial, gain, specific growth rate, feed efficiency EP significantly higher than those MP (P < 0.05). Water quality parameters like...
The control of bacterial pathogens, including Edwardsiella piscicida, in the aquaculture industry has high economic importance. This study aimed to identify a potential live vaccine candidate against E. piscicida infection minimize side effects and elicit immunity host. evaluated virulence factors CK108, with special focus on flagella. two important homologous flagellin genes, namely flagellin-associated protein (fap) domain-containing (fdp). CK226 (Δfap), CK247 (Δfdp) CK248 (Δfap, fdp)...
Streptococcus iniae는 대표적인 어류병원균으로 인수공통의 질병을 일으킨다. S. iniae FP5228에 존재하는 병원성 인자를 찾고자 하는 연구과정에서 iniae를 24시간 이상 배양한 배양액에는 살아있는 균의 수가 급격하게 감소하는 현상을 발견하였다. 이 현상은 FP5228 균이 가지고 있는 14 kb plasmid 상에 toxin/antitoxin (TA) system의 구성요소인 toxin ζ와 antitoxin e 유전자가 관련이 있을 것이란 가설을 설정하였다. IPTG와 arabinose에 의해 e의 발현이 조절되는 pBP1140 vector system을 구축하였다. E. coli/pBP1140 균주는 toxin이 발현되는 조건에서 초기 생육이 느려졌고, 현미경의 관찰에서 균체가 길어짐을 확인하였다. 균주가 가진 plasmid를 없앤 CK287을 제조하였다. CK287 균은 배양 중 사멸되는 보이지 않았고, biofilm 생성능력도 감소하였고...
