Polycyclic aromatic hydrocarbons (PAHs) consist of a group over 100 different organic compounds mainly generated by anthropogenic activities. Because their low water solubility, they tend to be accumulated in sediment, where degradation rate is very low. Few studies have been carried out so far investigate the effects PAHs on Artemia franciscana. easy manage at laboratory scale, but it not sens...

The application of magnetised water in aquaculture is still in its infancy. This study is a step towards gaining a better understanding of the effect of magnetism on water properties and on the biology of culture organisms, such as the brine shrimp, A. salina. The present study evaluates the effects of magnetic field exposure on water properties which in turn affect the hatchability of A. salin...

BACKGROUND Artemia (brine shrimp) is used as feed for fish fry and shrimp in aquaculture. Two employees in a Norwegian aquaculture research farm reported having chest symptoms when working in an Artemia hatch room. AIMS To determine the presence and prevalence of Artemia sensitization at the farm and the extent of any Artemia-related respiratory and hand skin symptoms and to identify the alle...

In the Crimean Peninsula, there are several hypersaline lakes that have hydromineral and biological resources. However, they under a significant anthropogenic load, which together with climate change leads to negative consequences for ecosystems. The aim of work was study seasonal changes physicochemical parameters water (temperature, pH, oxygen content, salinity, redox potential Eh, optical de...

Free mechanosensory neuromasts of larval fishes have been described as playing a complementary role to vision in feeding behaviour (Disler, 1971; Iwai, 1972a,b). In certain species or under limited conditions, free neuromasts play a major role in detecting prey. The larvae of mottled sculpin Cottus bairdi can feed on Artemia in the dark by using free neuromasts (Jones and Janssen, 1992). Artifi...

The growth ofCalanus finmarchicus nauplii was studied through three spawning seasons (2007, 2009, and 2011) using flow-through tubes. Natural seston was collected every second day and added as food source using a peristaltic pump. A mixture of cultured microalgae supplied in surplus concentration was used as a control treatment. No significant correlation between growth and food concentration m...

The effect of adding inulin to balanced diets for tropical gar (Atractosteus tropicus) larvae on growth, survival, digestive enzyme activity, and antioxidant activity was evaluated. were supplemented with 0.5, 1.0, 1.5, 2.0, 2.5% in addition a control diet (0% inulin). A total 1800 A. tropicus distributed 18 tanks used; the fed five times day (8:00, 11:00, 13:00, 15:00, 18:00) Artemia nauplii f...

ABSTRACT The green water technique uses microalgae in the of indoor larviculture, providing a darker environment to favor fish growth, welfare and health. We evaluated growth performance locomotor activity after light exposure pirarucu (Arapaima gigas) larvae reared or clear water. During one test, (3.6 ± 0.3 cm; 0.36 0.1 g) were 50-L circular tanks (n = 3 per treatment, 50 tank) static system ...
