Biofloc Technology (BFT) in Aquaculture: What Goes Right, What Goes Wrong? A Scientific‐Based Snapshot

open access: yesAquaculture Nutrition, Volume 2024, Issue 1, 2024.
Aquaculture is a crucial industry that can help meet the increasing demand for aquatic protein products and provide employment opportunities in coastal areas and beyond. If incorrectly manage, traditional aquaculture methods can have negative impacts on the environment and natural resources, including water pollution and overuse of wild fish stocks as ...

cDNA cloning, expression and antibacterial activity of lysozyme C in the blue shrimp (Litopenaeus stylirostris)

open access: yesProgress in Natural Science, 2009
The gene coding for lysozyme in blue shrimp (Litopenaeus stylirostris) was cloned, sequenced and expressed in pET-32a vector. The deduced amino acid sequence of F. merguiensi lysozyme showed 37-93% similarity with the mouse, human, chicken, and tiger prawn counterparts. The lysozyme was purified to homogeneity and observed as a band of approximately 15

Combined effect of external ammonia and molt stage on the blue shrimp Litopenaeus stylirostris physiological response [PDF]

open access: yesJournal of Experimental Marine Biology and Ecology, 2004
NH3-N) for 24 hours. Only shrimps in stages C, D0, D1 and D2 were used for the analysis. Haemolymph was assayed for osmoregulatory capacity (OC), magnesium ion (Mg ion), total proteins, oxyhaemocyanin, lactate and glucose. Molt stage had an effect on OC, Mg ion and total proteins in control shrimps, and on OC, Mg ion and lactate in treated animals ...

Effect of Different Oxygen Concentrations on Physiological Energetics of Blue Shrimp, Litopenaeus stylirostris (Stimpson) [PDF]

open access: yesThe Open Zoology Journal, 2011
The influence of different oxygen concentrations on the bioenergetics parameters, osmoregulatory capacity and O:N atomic ratio of the blue shrimp, Litopenaeus stylirostris (Stimpson), was determined under laboratory conditions; shrimp were acclimated at 28 oC and 25psu and exposed to three different oxygen concentrations 2, 4 and 6 mg L -1 .

Effect of dietary protein level on growth and energy utilization by Litopenaeus stylirostris under laboratory conditions [PDF]

open access: yesAquaculture, 2007
Abstract A study was conducted using a bioenergetics approach to generate information on energy requirement and feed utilization of Litopenaeus stylirostris. Animals (initial mean weight 21 ± 1 g were fed ad libitum six experimental diets, ranging from 25 to 58% crude protein (CP), for 50 days.

Changes in Hemocyte Counts in Litopenaeus stylirostris Subjected to Sublethal Infection and to Vaccination

open access: yesJournal of the World Aquaculture Society, 2000
Abstract.— A study was conducted with juvenile Litopenaeus stylirostris to evaluate the impact on total hemocyte counts of the injection of (1) formalin‐killed Vibrio penueicida cells (vaccine) and (2) a sublethal infection with a moderately pathogenic strain of Vibrio alginolyticus.
