The production of appropriate genetically modified organisms (GMOs) offers considerable opportunities for more efficient and more effective aquaculture across a wide range of species. Although this potential is being realized in crop production with over 60 million hectares under cultivation, there has been no commercial use of GMOs in aquaculture. Here we review the nature of GMOs, the range o...
Plant breeders and educators working with the International Potato Center (CIP) needed freely available statistical tools. In response, we created first a set of scripts for specific tasks using the open source statistical software R. Based on this we eventually compiled the R package agricolae as it covered a niche. Here we describe for the first time its main functions in the form of an artic...
Received: 06, May, 2015 Final Accepted: 11, June, 2015 Published Online: 16, June, 2015 Aquaculture is an activity that has many interactions with the surrounding environment using resources and producing changes in the ecological system. Aflatoxins are distributed worldwide. Aspergillus species are able to grow in a wide variety of substrates and under different environmental conditions. Toxin...
Water quality management is one of the key problems for intensive aquaculture. In order to predict the aquaculture water quality accurately, the paper proposes an Improved Gray Model for aquaculture water quality prediction. The Gray Model is improved and combined with the BP Neural Networks to implement the prediction. The Improved Gray Model serves as the main body for prediction and BP Neura...
Aquaculture development in Africa has lagged far behind that seen in Asia. It currently produces less than 5% of Africa's fish. Over the past decade, however, growing demand, the availability of suitable technologies and growing capacity has produced aquaculture success stories in several countries. In Egypt, for example, aquaculture production has grown 10 fold since the 1990s. In Uganda produ...
Wastewater effluent from aquaculture ponds can affect aquatic ecosystems. To mitigate this problem, we designed 2 sets (southern and northern) of land-based and farm-scale sequential integrated multi-trophic aquaculture (IMTA) systems in order to reduce water pollution and to diversify and optimize aquaculture products in coastal southern Taiwan. In each system, the 1st pond cultivated milkfish...
Sustainably feeding the world’s growing population represents one of our most significant challenges. Aquaculture is well positioned to make contributions towards this challenge. Yet, the translation of aquaculture production innovations into benefits for rural communities is constrained by a limited understanding of the social dynamics that influence the adoption of new agricultural practices....
We provide an overview of selected recent operational applications of satellite remote sensing and marine Geographic Information Systems (GIS) procedures to the practice of sustainable aquaculture in southern Hokkaido, Japan, focusing mainly on kelp and scallop aquaculture. We also developed a suitable aquaculture site-selection model (SASSM) for suspension culture of Gagome (a kelp species) in...
One of the most promising applications of hot water is aquaculture. Temperature is one of the most principle parameters affects aquaculture life. It can cause stress and mortality or superior environment for growth and reproduction. Shrimp is warm water aquaculture type need hot water supply. To increase pond production it is necessary to keep water temperature at 34C. Artificial intelligence (...
Aquaculture activities are embedded in complex social-ecological systems. However, aquaculture development decisions have tended to be driven by revenue generation, failing to account for interactions with the environment and the full value of the benefits derived from services provided by local ecosystems. Trade-offs resulting from changes in ecosystem services provision and associated impacts...
