“…Talas (2009) reported that propolis has protective haematological and biochemical effects on rainbow trout. Meurer (2009) indicated the potential use of brown propolis extract as a growth promoter to Nile tilapia fingerlings. Our study finds that the addition of propolis to the diet of trouts leads to the improvement of life characteristics of the aquaculture fish.…”

The aim of our study was to evaluate the effect of propolis on mortality of fish eggs due to mycosis, to study its efficacy on the fish growth rate and to analyze the histochemical and ultrastructural characteristics of muscle fibres. We evaluated the muscular development of fish in two different experimental conditions: traditional feeding and feeding with addition of propolis (groups A and B, respectively). The study was carried out on two species of teleosts bred in Italy, Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout). The use of propolis reduced mortality of fish eggs. The muscles were stained for myosin ATPase and succinic dehydrogenase to evaluate fibre type. The area, maximum and minimum diameter for each fibre type in relation to the body length were measured. The animals fed propolis showed a more rapid muscular growth compared to control fed the standard diet. Fibres were larger in the Salmo trutta than in the Oncorhynchus mykiss in both groups. In fish of A group, myotomal muscle, the presence of giant fibres and index of environmental stress was noticed. This type of study is valuable in order to extend the use of propolis as an antifungal agent and a natural product that can improve fish farming. ATPase and SDH activities, specific growth-rate, ultrastructural analysisEuropean aquaculture has shown a steady increase during the last twenty years, thanks to many initiatives promoted by the European Community to support this sector. But there are still many problems to solve, such as the support of ecocompatible activities, the improvement of animal health and welfare, product quality and consumer health assurance. Propolis is a mixture of various amounts of beeswax and resins collected by the honeybee from plants, particularly from flowers and leaf buds (Krell 1996). The colour of propolis ranges from yellow to dark brown depending on the origin of the resins. Propolis has attracted the researchers' interest in the last decades due to its biological and pharmacological properties, such as immunomodulatory, antitumor, antimicrobial, antiinflammatory, and antioxidant properties (Kanbur et al. 2009). The goal of this study was to analyze, for the first time, the influence of propolis on the fish muscular development and on the structural and ultrastructural characteristics of muscle fibre types. This study opens a new perspective on the investigation of biological properties of propolis, mainly with respect to the influence on the development of the trout and the mortality of fish eggs. Materials and MethodsThe following species of freshwater fish were used in our study: Salmo trutta (brown trout) and Oncorhynchus mykiss (rainbow trout). Experiment with eggsIn order to evaluate the effect of propolis on mortality of fish eggs, approximately 600 eggs (half and half) were placed in 3 "Californian tanks" arranged in cascade. Untreated samples (about 250 eggs) were used as control. The eggs were rinsed in propolis solution (1%) for 15 min, once every four days and then they were ...

“…Studies in mammals verified that propolis decreased dead and abnormal sperm and increased testosterone in rats (Yousef and Salama, 2009) and significantly increased body weight, and the relative weight of the testes and epididymis in rabbits (Yousef et al, 2010). In fish, propolis has been extensively used as a growth promoter (Meurer et al, 2009), immunostimulant (Talas and Gulhan, 2009) and hepatoprotective agent (Deng et al, 2011). However, no data are available regarding the effect of propolis on fish fecundity or semen quality.…”

This study aimed at identifying the effects of propolis and honeybee pollen (HBP) on growth performance, fecundity and some hematological indices of liver and kidney functions of Nile tilapia ''Oreochromis niloticus'' supplemented with 2.5% of propolis or HBP in diet for 21 days. The results showed that dietary propolis or HBP significantly (P<0.05) improved Specific Growth Rate (SGR), Average Daily Gain (ADG) and Feed Efficiency ratio (FER). Propolis significantly (P<0.0001) increased the percentage of O. niloticus with ripened eggs. Microscopically, the ovaries were seen to contain a large number of oocytes >4 mm in the treated groups. In male, HBP feeding significantly (P<0.05) increased testicular weight, gonadosomatic index and improved the semen quality. Nevertheless, propolis treated males showed a significant (P<0.05) increase in head abnormalities among all groups. Sections from the testes of HBP-fed group appeared highly active and showed accumulated sperms in seminiferous tubules. Propolis or HBP significantly (P<0.001) decreased the serum ALT. Concluding that, supplementation of fish diet with either propolis or honeybee pollen is promising a beneficial effect for fisheries due to its potential improving effect on the growth rate and fecundity and preserving some biochemical indices of liver and kidney functions of O. niloticus.

“…In sex-reversed Nile tilapia fingerlings, the reduction of hepatosomatic index was observed when feed was supplemented with probiotic additives (Meurer et al, 2009a). Meurer et al (2009b) suggested that this decrease in hepatosomatic index could be related to the nutritional aspect of fish and their growth rate, indicating that their metabolic reserves (glycogen/lipid) are used to enhance immunity against opportunistic organisms.…”

-This study evaluated the effect of feed supplementation (at doses of 0, 50, 100, 150, and 200 mg/kg) with SALUTO ® , a microencapsulated blend of essential oils including carvacrol, cinnamaldehyde, 1,8-cineol, and pepper oleoresin, in Nile tilapia (Oreochromis niloticus) broodstock on reproductive and growth parameters during the initial phase of rearing. The growth parameters, somatic indexes and gonadal and hepatic parameters were analyzed. Quantitative parameters of growth, ovary fat and crude protein were not affected by supplementation of the additive. However, an increase in crude protein in the female liver was observed in correlation with increased essential oil levels. The female hepatosomatic index was also correlated with supplementation of essential oils. Feeding Nile tilapia broodstock diets containing an essential oil compound (SALUTO ® ) affects only the females, promoting an increase in liver protein inclusion and hepatosomatic index without impairing performance.
