This study investigated the effects of adding green macroalgae gutweed (Ulva intestinalis) powder to zebrafish (Danio rerio) feed at different levels on innate immune responses, antioxidant defence, and gene expression. A total of 600 zebrafish ( 0.3 ± 0.08 g) were randomly allocated to 12 aquariums in four treatments with three replicates (50 fish...
The present study was performed to study possible effects of Dictyota dichotoma which is a brown macroalgae on whole body extract (WBE) and skin mucus immune parameters, antioxidant enzyme activities as well as expression of growth, immune, and antioxidant related genes in zebrafish (Danio rerio). Zebrafish with an average weight of 0.3 ± 0.08 g we...
The effects of adding laurel oil to the experimental diet on growth performance, biochemical compositions of fish and feeds, sand liver and intestine histology in Nile tilapia (Oreochromis niloticus) juveniles were evaluated. 180 fish (12±0.02 g) were used in the study. They were randomly placed in 12 tanks with a volume of 500 liters, with 15 fish...
Bu çalışmada Grobiyotik-A’nın yeşil kaplan karidesinin büyüme, yaşama oranı ve yem değerlendirme oranı üzerine etkileri araştırılmıştır. Deneme yemleri, ticari levrek yemine 4 farklı düzeyde (% 0, 0,5, 1 ve 2) Grobiyotik-A ilave edilerek hazırlanmıştır. Ortalama ağırlığı 1,65±0,08g olan Penaeus semisulcatus yavruları 0,785 m2'lik silindirik tanklar...

Herbal additives and vitamins have gained considerable attention to improve fish health. This study investigates the effects of vitamin C (VC), Thymus vulgaris L. essential oil (TE), and quercetin (QR) supplementation on growth performance, digestive enzyme, body composition, and biochemical parameters of common carp (Cyprinus carpio). Four hundred...
In the present study, the effects of dietary Halopithys incurva, a red macroalgae species, (0.25, 0.50, 1%) on whole-body serum and skin mucus immune system, antioxidant system and expression of various genes in zebrafish were investigated. At the end of the 8-week study, total protein, total immunoglobulin and lysozyme activities in whole-body ser...
In this study, the effects of GroBiotic®-A on growth performance, survival rate, and feed conversion ratio of green tiger shrimp were investigated. The commercial GroBiotic®-A was added to the commercial sea bass feed diet at four different levels (0, 0.5, 1, and 2%). Penaeus semisulcatus juveniles with an average weight of 1.65±0.08 g was stocked...

Aquaculture is one of the fastest growing and promising sectors of
food production all over the world. In commercial aquaculture, it is
very important to elevate disease resistance, feed efficiency and
growth performance of cultured aquatic species. If these are realized,
overall production costs would be remarkably reduced. Antibiotics

Using Ross et all (2000) technique, fish placed in individual plastic bags containing 5ml of 100 mM ammonium bicarbonate (NH4HCO3p) H 7.8 for approximately 1 min. or
Using Palaksha et all 2008 technique, the fish skin mucus was collected by gentle scraping using a soft rubber spatula.
I would appreciate any suggestion
I want to apply a trial in a commercial fish farming. I will research some non specific immune parameters. There are 30000fish/each pool. How many numbers fish should I use to resemble all populations?
Thank you for your interesting.
