Abstract:
... To avoid mechanical compression of spermatozoa during the cryopreservation, a high dilution ratio with the cryoprotective medium is applied. Due to this, the sample volume increases, which entails increased cryobank capacity. Moreover, the high volume of cryomedias does not allow to fertilize of large volumes of eggs in practical artificial reproduction of common carp aquaculture. The current stud ...

Abstract:
... Protein arginine methyltransferases (PRMT6) has been shown to negatively regulate interferon (IFN) production in mammals, however, the role of teleost PRMT6 in IFN signaling remains largely unknown. In our previous study, black carp (Mylopharyngodon piceus) PRMT6 (bcPRMT6) has been identified to inhibit bcTBK1/bcIRF3 cascade. In this study, bcIRF3-induced transcription of bcIFNa, bcIFNb, bcp50 and ...

... In aquaculture, the therapeutic potential of andrographolide had been beneficially documented but still restricted owing to its high dosage and low bioavailability. To maximize andrographolide's potential value in carps, we want to create an effective delivery mechanism. During the 8-week Cyprinus carpio feeding trial, we aimed to test a low dose (0.05 g kg⁻¹ or 0.005%) andrographolide-supplemente ...

Abstract:
... Tilapia is the second most prolific species grown in aquaculture after carp, and is widely grown in >100 countries. Myostatin (MSTN) has been proved to be a negative regulator of skeletal muscle growth. Mutation of MSTN gene resulted in significant increase in both body size and muscle mass in vertebrates, mostly with a species-specific effect. To generate a new strain in Nile tilapia (Oreochromis ...
... The spring viremia of carp virus (SVCV) is a serious deadly virus that results in high mortality and significant economic losses in the aquaculture industry of carp species. The present study was conducted to evaluate the antiviral effect of 8 natural compounds against SVCV in epithelioma papulosum cyprinid (EPC) cells and common carp (Cyprinus carpio). Herein, artemisinin was identified to inhibi ...

Abstract:
... Freshwater carp polyculture farming has grown an important production system in Bangladesh in terms of income, nutrition supply, and employment generations in past decades. This study determines the farm-level technical inefficiency along with yield gap and yield loss among a sample of 183 farms practicing carp polyculture in Bangladesh. The result of technical efficiency shows that the farmers ar ...

Abstract:
... BACKGROUND: Three image analysis methods to measure visual texture were applied to an image with much texture (scaled carp), and one with little texture (mirror carp). For each method, the effect of image rotation at 0°, 10°, 20°, 30°, 45°, 60°, 75° and 90° was evaluated. RESULTS: Rotation did not change energy (E) and entropy (H) calculations using image histograms. Using co‐occurrence matrices w ...

Abstract:
... The release of hatchery-reared fish fry for restocking is important for the enrichment of fishery resources; however, the effective evaluation of the success rate of marking such fish is challenging. We exposed juvenile crucian carp (Carassius carassius) to a single concentration of SrCl₂·6H₂O for 5 d and evaluated the efficiency of Sr marking of the fish otoliths (sagittae, asterisci, and lapilli ...

Abstract:
... Climate change will expose the food‐producing sector to a range of challenges. Inland aquaculture farms are particularly vulnerable, due to the difficulty in changing their location, and therefore require specific tools to predict the influence of direct and indirect effects on production, environment and economic feasibility. The objective of our study was to apply a simple set of models to produ ...

Abstract:
... During evolution, the fish adopted versatile spawning tactics, which allowed them to use sperm competition effectively and prevent fertilization by inappropriate male gametes. Ovarian fluid (OF) affects spermatozoa performance in several fish species, as shown mainly in salmonids, and likely contributes to their reproductive tactics. Common carps utilize different spawning behavior compared to sal ...
