Alnus glutinosa, Fraxinus excelsior and Papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. As part of our continuing screening of plant extracts for activities, the extracts of A. glutinosa, F. excelsior and P. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. Among ...
It has been found that appropriate probiotic applications increased growth performance and disease resistance in shrimp. Bacillus subtilis has been suggested as a potent probiotic in improving growth performance and enhancing immune response in white shrimp, Litopenaeus vannamei. The aim of this work was to evaluate the possible effect of B. subtilis administration on the meat fatty acid profil...
Speckled shrimp (Metapenaeus monoceros), is a commercially important prawn in the embayments and estuaries of the Mediterranean Sea. It is originally a Lessepsian species which had migrated from the Red Sea into the Mediterranean Sea through the Suez Canal. This study was carried out in the North-eastern Mediterranean Sea between November 2009 and October 2010 with monthly sampling of speckled ...

In this 30-day experiment, the effect of probiotics (Bacillus clausii, commercial probiotics: Enterogermina) and prebiotics (Galactooligosaccharides, GOS) on growth red cherry shrimp (Neocaridina davidi) has been investigated for 30 days. The trial was conducted with 270 shrimps (initial weight: 0.24±0.03 g) in 27 plastic tanks (volume 0.01 m3 area 0.05 m2) representing 9 groups. Except control...
This study investigated the effects of replacing commercial feeds with fresh black soldier fly larvae (BSFL) on immune enzyme activities, water quality in culturing environment, and intestinal microbiota Pacific white shrimp ( Litopenaeus vannamei ). Five different feeding regimes were designed, which 0% (control group), 25%, 50%, 75%, 100% replaced equal wet weight BSFL, respectively. The expe...
The compound eyes of mantis shrimps (stomatopod crustaceans) include an unparalleled diversity of visual pigments and spectral receptor classes in retinas of each species. We compared the visual pigment and spectral receptor classes of 12 species of gonodactyloid stomatopods from a variety of photic environments, from intertidal to deep water (> 50 m), to learn how spectral tuning in the differ...
Vibrio parahaemolyticus is a causative agent of human serious seafood-borne gastroenteritis disease and even death. Shrimps, often eaten raw or undercooked, are an important reservoir of the bacterium. In this study, we isolated and characterized a total of 400 V. parahaemolyticus strains from commonly consumed fresh shrimps (Litopenaeus vannamei, Macrobrachium rosenbergii, Penaeus monodon, and...
The compound eyes of mantis shrimps, a group of tropical marine crustaceans, incorporate principles of serial and parallel processing of visual information that may be applicable to artificial imaging systems. Their eyes include numerous specializations for analysis of the spectral and polarizational properties of light, and include more photoreceptor classes for analysis of ultraviolet light, ...
