Effects of C/N ratio and periphyton substrates on pond ecology and production performance in giant freshwater prawn Macrobrachium rosenbergii (De Man, 1879) and tilapia Oreochromis niloticus (Linnaeus, 1758) polyculture system
Type: Journal Article
The production performances of giant freshwater prawn Macrobrachium rosenbergii and Nile tilapia Oreochromis niloticus in C/N-controlled periphyton-based polyculture systems were evaluated in triplicate. The result of this ...
Effect of using periphyton substrate (Bamboo stems) on water quality, phytoplankton, zooplankton, periphyton and growth performance for tilapia, mullet and catfish in earthen ponds
Type: Journal Article
This experiment shows that the bamboo substrate improved water quality, survival rate and total production of fish.
Effect Of Different Prepared Antigens Of Pseudomonas fluorescens On Specific And Non-Specific Immune Response Of Nile tilapia (Oreochromis niloticus)
Type: Journal Article
The current work aimed to study four different prepared Ps. fluorescensantigens (formalin killed bacterin, extracellular product (ECP) suspension, sonicated cells (SC) suspension and mixture of ECP and SC suspension) to ...
Efficacy and safety of boric acid as a preventive treatment against Saprolegnia infection in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Saprolegniosis is a worldwide fungal-like infection affecting freshwater fishes and their eggs. Reports show high mortalities and subsequent economic losses annually from Saprolegnia infections. Most therapeutants against ...
Genetic parameters for uniformity of harvest weight and body size traits in the GIFT strain of Nile tilapia
Type: Journal Article
Animal breeding programs have been very successful in improving the mean levels of traits through selection. However, in recent decades, reducing the variability of trait levels between individuals has become a highly ...
Comparison of Asian aquaculture products by use of statistically supported life cycle assessment
Type: Journal Article
In this article, the authors investigated aquaculture production of Asian tiger shrimp, whiteleg shrimp, giant river prawn, tilapia, and pangasius catfish in Bangladesh, China, Thailand, and Vietnam by using life cycle ...
Differences in sexual size dimorphism among farmed tilapia species and strains undergoing genetic improvement for body weight
Type: Journal Article
Many tilapia (Oreochromis spp.) farmers produce all-male populations because of the superior growth rate of males compared to females. To investigate differences in body weight at harvest of males and females among different ...
Assessment of immune response supplemental immunoton and bovine lactoferrin as alternatives to antibiotics in nile tilapia (Oreochromis niloticus)
Type: Journal Article
An experiment was conducted to two different immunostimulants were investigated to detect changes in the activity of innate non-specific immune response, disease resistance and growth performance as alternatives to antibiotics ...
Value chain analysis of the aquaculture feed sector in Egypt
Type: Journal Article
This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability. The strengths and weaknesses of each link of the value ...
Performance of mono-sex tilapia (Oreochromis niloticus) in rice field with different ditch size
Type: Journal Article
The effects of ditch size on growth and production of mono-sex tilapia, Oreochromis niloticus in rain fed concurrent rice–fish system were technically and economically evaluated for a period of 4 months. Three different ...
