Municipal fishermen experience collisions and being rammed by larger marine vessels. Automatic identification system (AIS) can be a solution for them, if not for its high cost. Likewise, in emergency situations, due to limited cellular coverage at sea, fishermen do not have the means to communicate ...
The blue crab (Callinectes sapidus) is a dominant ecological species of high commercial value. Spawning stock and recruitment of the Chesapeake Bay population declined by 80% in the 1990s. After severe management actions were implemented in 2008, female abundance rebounded to pre-1994 levels and stabilized. ...
Shrimp farming is a major industry covering 23% of Philippine annual aquaculture production, which requires performing better management practices (BMPs) including growth monitoring and feed management. Traditionally, growth is monitored manually using analog weighing scale and caliper; but the manual ...
Offshore fish farms remain a vibrant and important production sector for seafood in the aquaculture industry. Being offshore with no grid-based power supply, the continuity and quality of the power supply to the fish farm is crucial. This paper presents an implementation of an Internet of Things (IoT)-based ...
This study presents the design and development of a nutrient film technique hydroponics system for lettuce. Hydroponics is a method of cultivating crops with the use of water with nutrient solutions as medium. This nutrient film technique hydroponics system was built as an alternative to traditional ...
Monitoring the dynamics of fish behavior is impactful both in the research for fisheries and aquaculture production. One of the most explored approaches to monitor the fish is tracking-by-detection along with computer vision. Presently, there are several challenges in this field, including underwater ...
This paper shows the design, construction, and implementation of an Automated Aquaponics system. Most of the commercial aquaponics system in the Philippines is grid-dependent thus making it cost-ineffective. The design of the system has three-part, hydroponics, aquaculture, and control systems. The ...
Segmentation is a challenging task for the complex and low-quality underwater images, as this is prerequisite to advanced tasks in fish monitoring such as fish detection and classification. A demand exists for underwater image segmentation algorithms that can robustly segment fish from its background. ...
Food shortage is a serious problem facing the world and is prevalent in urban areas. The scarcity of food is mainly caused by crop failure. Environmental factors offered by the rural areas determine the condition of crops to be produced. This scenario pomps, the explication of urban farming. However, ...
This paper introduces the development of monitoring and maintaining optimal water quality in an aquaponics system. The design is based on the hydroponics system’s Nutrient Film Technique (NFT) in which plant roots are being exposed to a thin layer of nutrient water in a long narrow channel. The design ...
Aquaponics is an integration of aquaculture and hydroponics and the naked eye cannot predict and distinguish abiotic factors specifically in the water. The study used a Costus Igneus (insulin plant) to discover if it will grow successfully in the Aquaponics setup rather than traditional soil setup and ...
Last May 2019, fish farms in Taal Lake suffer from fish kill resulting in an estimated loss of 405 tons of fish. It was reported that the measured water sample from the lake shows significant loss of dissolved-oxygen due to over-crowding of fish farm. With the crisis mentioned, recent studies utilize ...
The gut microbiome plays a key role in animal health and metabolism through the intricate functional interconnection between the feed, gut microbes, and the host. Unfortunately, in aquaculture, the links between gut microbes and fish genetics and production phenotypes are not well understood. In this ...
Recent literature on marine fish farming brands it as potentially compatible with sustainable resource use, conservation, and human nutrition goals, and aligns with the emerging policy discourse of ‘blue growth’. We advance a two-pronged critique. First, contemporary narratives tend to overstate marine ...
Microalgae are often used as nutritional supplements for aquatic animals and are widely used in the aquaculture industry, providing direct or indirect nutrients for many aquatic animals. Microalgae are abundant in nature, of high nutritional value, and some of them are non-toxic and rich in antioxidants ...
With the growth of sensing, control and robotic technologies, autonomous underwater vehicles (AUVs) have become useful assistants to human divers for performing various underwater operations. In the current practice, the divers are required to carry expensive, bulky, and waterproof keyboards or joystick-based ...
Simple Summary Research for alternative protein sources that may replace fish meal and fish oil in fish diets is one of the ongoing tasks for aquaculture. Sturgeons role captive fish production increases due to the rapid decrease in its wild stocks during the 20th century. Insect meals are a novel ...
Small-scale fisheries are responsible for landing half of the world’s fish catch, yet there are very sparse data on these fishing activities and associated fisheries production in time and space. Fisheries-dependent data underpin scientific guidance of management and conservation of fisheries systems, ...
Abstract Coronavirus disease 2019 (COVID-19) emerged from the West District of Southern China Seafood Wholesale Market in late December 2019 and has been declared a global pandemic by the World Health Organization (WHO). Infection with severe acute respiratory syndrome coronavirus (SARS-CoV-2) presents ...
Abstract The stock‐specific distribution of maturing salmon in the North Pacific has been a persistent information gap that has prevented us from determining the ocean conditions experienced by individual stocks. This continues to impede understanding of the role of ocean conditions in stock‐specific ...
