Coral reef fishing and coral-algal phase shifts: implications for global reef status
Type: Journal Article
Coral reef fisheries support tens of millions of people, mostly in developing countries. Fishing on reefs can be classified into three stages: manageable, ecosystem-overfished, and Malthusian-overfished. Fishing with ...
Seaweeds preferred by herbivorous fishes
Type: Journal Article
Marine macrobenthic algae (or seaweeds), epiphytic microalgae, and other aquatic plants constitute the main food items of marine herbivorous fishes. About 5% of all fish species are herbivorous; only 30% of these are marine, ...
Control of microcystis aeruginosa using tannic acid
Type: Journal Article
One of the most difficult challenges facing the commercial fish producers is how to keep the constant balance that required maintaining a stable relationship among the water, fish and microscopic flora and fauna in their ...
Impacts of harmful algae on seafarming in the Asia-Pacific areas
Type: Journal Article
Seafarming to produce human food has recently intensified, particularly in the Asia-Pacific region. Disastrous impacts of harmful phytoplankton blooms, however, have been experenced during the past 20 years. In extreme ...
Cell wall disruption: An effective strategy to improve the nutritive quality of microalgae in African catfish (Clarias gariepinus)
Type: Journal Article
The rigid cell walls of microalgae may hinder their utilization in fish feeds. The current experiment assessed the correlation between the accessibility of microalgae nutri- ents and their in vivo digestibility in African ...
Food potential of aquatic macrophytes
Type: Report
Presents a review of the pathways in which aquatic macrophytes may be involved in the food production process, directly as human food, as livestock fodder, as fertilizer (mulch and manure, ash, green manure, compost, biogas ...
The role of Spirulina platensis (Arthrospira platensis) in growth and immunity of Nile Tilapia (Oreochromis niloticus) and its resistance to bacterial infection
Type: Journal Article
The current study was designed to optimize the dietary levels of Spirulina platensis in Oreochromis niloticus; this was tested via graded levels. Six isonitrogenous and isocaloric rations containing graded levels of dried ...
Enhancement of grazing gastropod populations as a coral reef restoration tool: predation effects and related applied implications
Type: Journal Article
In this study, we aimed to evaluate the efficacy of adding T. niloticus to control epilithic algal biomass and enhance coral recruitment on artificial substrata at a heavily fished reef in northwestern Philippines. Our ...
Effect of freshwater toxic and non toxic cyanobacteria, (Microcystis aeruginosa) strains on some biochemical parameters of Oreochromis niloticus
Type: Journal Article
This study was planned to determine the grazing rate of O. niloticus from both toxic and non toxic strains of Microcystis aeruginosa with its effect on fish health through study of some clinical signs, hematological and ...
Utilization of blue green algae (Anabena wisconsienense) as a feeding and biofertilization for Nile tilapia (Oreochromis niloticus) cultivated in rice fields
Type: Journal Article
This study has been carried out to investigate the growth performance and economic efficiency as well as pond productivity of Nile tilpia fingerlings cultured in rice fields as affected by dried blue green alga for nutrition ...
