Abstract:
... The growth, metabolic and blood parameters and oxidative stress biomarkers effects of adding Lippia alba essential oil (EO) to the diet (0=control, 0.25, 0.5, 1.0 or 2.0mL EO per kg diet) of juvenile silver catfish were investigated for 60days. Liver and muscle were used to measure the glucose, glycogen and lactate levels. Lipid peroxidation (LPO) was assessed as a marker of oxidative damage. Enzy ...

There has been an increase in the number of species isolated from fish or fish farm environments, some of them possibly associated with disease. Fourteen Flavobacterium-like isolates recovered from gills, surface of eggs and liver of rainbow trout were characterized ...

Abstract:
... Long chain polyunsaturated fatty acid (LC-PUFA) biosynthesis is limited in many marine species, normally due to lack of Δ5 fatty acyl desaturase (Fad) activity. Among exceptions, abalone possesses considerable LC-PUFA conversion ability from C18 precursors. However, its characterization and relevant enzyme are not well characterized. Here we successfully cloned and characterized two Δ5 Fads in aba ...

Current Canadian lobster enhancement programs rely on the release of postlarvae (stages IV and V), which are still vulnerable to high mortality. We hypothesized that larvae enriched in triglycerides (TAG) and polyunsaturated fatty acids (PUFA) during their ...

Stock enhancement through the release of cultured juveniles has been suggested as a possible recovery tool for depleted red (Paralithodes camtschaticus) and blue (Paralithodes platypus) king crab populations in Alaska, USA. Considerable progress has been made in the past decade in red king crab culture technology, but similar technologies are less developed for blue king crabs. As part of a stock ...

Abstract:
... The present study examined the effects of elevated CO2 partial pressure on the specific dynamic action (SDA) and ammonia excretion in European eel (Anguilla anguilla) following forced feeding. Two different hypercapnic scenarios were investigated; one in which pCO2 oscillated between 20 and 60mmHg over 24hourcycles, and one in which pCO2 was constant at 60mmHg. Since high CO2 results in low pH wit ...

In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), it is necessary to establish the limit for acceptable O2 reductions; the hypoxia tolerance threshold. In the present study, effects of temperature (6, 12 and 18°C) and hypoxia ...

Abstract:
... Many fish of aquacultural importance including sturgeon and paddlefish have a history of polyploidy in their evolutionary lineages. Spontaneous autopolyploids have been detected in several sturgeon species in culture despite the fact that the induction of triploidy is not a management tool in farming sturgeon for meat and caviar. In 2010, we discovered two female spontaneous autopolyploid white st ...

Excess levels of dissolved nitrogen gas (N2) may occur in recirculating aquaculture systems, as a result of aeration efforts, localized occurrences of denitrification, or from insufficient degassing of makeup water. If levels of dissolved N2 are sufficiently high, or if oxygen (O2) is also maintained at or above saturation, this leads to a supersaturation in total gas pressure (TGP). Depending on ...
