Abstract:

Removal of nitrogen elements in culture water is one of the major concerns in recirculating aquaculture system (RAS). Maintaining a low concentration of nitrogen compounds is essential for a good quality of aquaculture production. Due to fish is very sensitive to the toxic ammonium/ammonia, nitrification biofiltration tank is often an integrate part of filtration in RAS to remove ammonium via nitrification. However, nitrate accumulation via nitrification in RAS is often observed during the operation, which is usually solved by replacing with the fresh water into the system. With the concern of

Abstract:

Intensive marine aquaculture may cause negative impacts on the aquatic environment by causing water pollution, algae bloom and reduction in biodiversity of the surrounding aquatic environment. The nutrient-rich effluents from aquaculture activities contain nitrogen and phosphate which serve as a nutrient source for bivalve, algae and invertebrates. Seaweed and mussels have been integrated with marine species in culture systems to remove the waste from aquaculture farms. The research has explored the nutrient uptake capacities of green seaweed (Ulva lactuca) and blue mussel (Mytilus edulis) int

With World Health Organization estimation of population increase to over 9 billion by 2050, malnutrition and food insecurity are predicated to be two of the main challenges facing the world in the future. Fish is a source of protein that can have a significant contribution for solving the global food crisis. Fish for human consumption is provided by both the aquaculture industry and the capture fisheries, however, the flat-lined production of seafood from capture fisheries means aquaculture production should double in number to provide enough protein by 2050.

Land based aquaculture systems are growing in popularity, and there is a drive to improve the efficiency of their energy and water systems for both economic and environmental benefit. Recirculating Aquaculture Systems (RAS) generally refer to systems that recycle their wastewater streams to be more or less a zero discharge facility. A more sustainable approach is emerging in the form of Integrated Aquaculture Systems (IAS) where maximum utility is realized from the various components so that fresh water use is reduced, water quality is improved, energy use is reduced, and new markets are creat

Recirculating aquaculture systems (RAS) produce aquaculture products on land with minimal discharge of waste products and minimal water loss. High costs associated with waste treatment for RAS have triggered the growth of integrated aquaculture systems (IAS) which incorporate macrophytes (aquatic plants) into the treatment train. The objective of this research was to examine a pilot scale inland marine IAS with three different methods for solids treatment: a sand filter followed by a plant bed, only a plant bed, and geotextile bags.

Abstract:

Fish farming or Aquaculture is a growing food-producing industry to culture the fish in artificially constructed tanks. A large number of fishes are reared in tanks for 100-150 days and produce food for the population. With increasing population and declining worldwide capture fishery, Aquaculture is perceived as a potential technique to meet the ever-expanding food demand without tarnishing the aquatic food chain. However, problems which are addressed in current systems like human intervention and unused feed material inhibit the production rate. This thesis provides methods and guidelines to

Integrated aquaculture systems (IAS) are a type of recirculating aquaculture systems (RAS) where the wastewater is treated and returned to the fish tanks. The important difference between the two is that in an IAS, wastes from the aquaculture component are recovered as fertilizer to produce an agricultural product whereas in an RAS, waste organics, nutrients and solids are treated and discharged. A pilot marine IAS at Mote Aquaculture Research Park in Sarasota, FL was studied for this project. Water quality monitoring, measurements of fish health and growth rates of fish and plants were perf

Six experiments were conducted to evaluate nitrogen uptake capacities of duckweed in barramundi recirculating aquaculture systems (RAS). Harvesting duckweed every four days increased the abundance and diversity of both heterotrophic and phosphate-solubilising bacteria, and maximised nitrogen uptake efficiency. A stocking density of less than 18.75 kg m-3 is recommended for culturing barramundi in integrated RAS. The inclusion of fermented duckweeds up to 35% is feasible without adversely affecting growth and physiological parameters of barramundi.

Abstract:

Aquaculture processes usually take place in remote and harsh environments, therefore its monitoring and supervision are constrained by several factors. Taking that into account, this MSc Dissertation proposes a technical solution for a remote supervision system for aquaculture platforms, which uses a sensoring method developed at CIBIO/InBIO. The proposed solution contemplates two different levels. At an upper level, there is a Gateway, an embedded data collection and communication system, based on a BeagleBone Black, which handles an I2C based sensor network and a SIM800 GSM module. At a lowe

碩士<br>國立高雄第一科技大學<br>電腦與通訊工程系碩士班<br>106<br>In recent years, Consumer consumption has dramatically increased with regard to food safety concerns. In order to reduce the harm more effectively, it has gradually moved towards organic researches that are non-toxic, pesticide-free, and free of antibiotics. Based on these reasons, the Energy Science and Technology Center of the university has completed the research and development program of the "Nontoxic Algal-bacterial Co-production Aquaculture Plant." However, due to cost of dissolved oxygen meter are found to be expansive in the market. Hence, the
