This study was carried out to investigate the effect of replacing fish meal protein with fermented soybean meal (FSM) in diets on growth performance, feed utilization, morphological parameters, body composition, activities of antioxidant and digestive enzymes and also blood biochemistry of juvenile olive flounder (Paralichthys olivaceus). Five isonitrogenic and isolipidic diets were prepare...

Background: Contamination of feeds with cadmium leads to oxidative stress in vital tissues such as gills and affects the fish survival. Therefore, an increase in the capacity of the antioxidant defense system and detoxification system of fish may reduce adverse effects of pollutants. This study investigated the protective effects of microalga Spirulina platensis against oxidative stress in gill...

A 15-wk feeding trial was conducted to examine the supplemental effects of Barodon on growth performance, gastrointestinal histology, feed digestibility and innate immunity in olive founder. A basal commercial diet was used as a control and two other diets were prepared by spraying 0.1% or 0.2% of Barodon. Triplicate groups of fish (BW, 145 g) were fed one of the test diets to apparent satiatio...

Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...

This paper describes an approach to determine melamine (MEL) in liquid milk, yogurt, whole milk powder, fish feed, and fish at residue levels using capillary zone electrophoresis with diode array detection (CZE-DAD) for the first time. Suspicious samples were extracted with 1% trichloroacetic acid while 1 mL of chloroform was used to precipitate fat in the real samples. After centrifuging and f...

The continuous and rapid growth of aquaculture in terms of size and annual total production has resulted in the need to seek for pragmatic measures to reduce the cost of production which feeding covers approximately 60%. This present work reviews the advances made in the use of palm oil as an alternative lipid source in aquafeeds. In this review it is documented that with respect to price, avai...

n-3 HUFA have been used as feed in rnass cultivation of fish larva.2'5i Recentlydocosahexaenoicacid(DHA)wasrepertedtobethernosteffective n-3 HUFA for the growth of fish fry,6'7) but there is no known method to enrich zooplankton specifically with DHA, In this paper we report on enriching Euglena gracilis with eicosapentaenoic acid (EPA) and DHA, E. gracitis cells are about SO"m in size, contain...

the freshwater angel fish (pterophyllum scalare schultze, 1823) is south american cichlid become very popular among aquarists. there is little information on their culture and aquarium husbandry. in this study growth performance and survival rate of angelfish subjected to different feeding frequencies were evaluated. four groups of angel fish juveniles (0.87 ± 0.01 g; 3.98 ± 0.08 mm) were fed e...

Two trials were conducted to determine the effect of dietary enrichment with arachidonic acid (ARA)-rich triacylglycerols fraction, obtained from the microalga Parietochloris incisa, on the recovery of guppies, Poecilia reticulata, from infection with Tetrahymena sp. Commercial feed (0.7 mg ARA g feed) was directly enriched with the algal hexane lipid extract. Three (12.5, 25.0, 50.0 mg ARA g f...
