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 ...
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 ...
Levels of some heavy metals in muscles and liver of freshwater farmed Fish at Abbassa
Type: Journal Article
In the present study, the levels of iron, zinc, cadmium, copper, lead, manganese, and calcium in muscle and liver tissues were investigated in different species of commercially available farmed fishes (Nile tilapia, striped ...
Survival, male morphotypes, female and male proportion, female reproductive status and tag loss in crosses among three populations of freshwater prawn Macrobrachium rosenbergii (de Man) in India
Type: Journal Article
The present study examined the variation in survival, proportion of male morphotypes, female and male proportion, female reproductive status and tag losses in nine crosses from a complete (3 × 3) diallel mating of three ...
Vulnerability of coastal livelihoods to shrimp farming: Insights from Mozambique
Type: Journal Article
Millions of people around the world depend on shrimp aquaculture for their livelihoods. Yet, the phenomenal growth of shrimp farming has often given rise to considerable environmental and social damage. This article examines ...
Classifying degrees of species commonness: North Sea fish as a case study
Type: Journal Article
Species commonness is often related to abundance and species conservation status. Intuitively, a "common species" is a species that is abundant in a certain area, widespread and at low risk of extinction. Analysing and ...
Integrated floating cage aquageoponics system (IFCAS): An innovation in fish and vegetable production for shaded ponds in Bangladesh
Type: Journal Article
Farmer participatory action research was carried out from July to December 2013 to design and construct a technology known as IFCAS (integrated floating cage aquageoponics system) for growing fish and vegetables in shaded ...
Genetic parameters for survival during the grow-out period in the GIFT strain of Nile tilapia (Oreochromis niloticus) and correlated response to selection for harvest weight
Type: Journal Article
The aims of this study were the estimation of genetic parameters for survival rate from tagging until harvest and the evaluation of the correlated response in survival rate to selection for harvest weight in the genetically ...
Are trunk lateral line anomalies and disoriented scale patterns in European seabass (Dicentrarchus labrax) influenced by genetics?
Type: Journal Article
Different kinds of defects are observed on farmed fish, and while a lot of research has concentrated on skeletal abnormalities, little is known on scale anomalies. In this paper, a survey for lateral line shape anomalies ...
