Artificial Intelligence in Aquaculture
The seventh and final installment in the series “Happy Fish – How Aquaculture Operators are Growing Better Fish.” While we will only be able to scratch the surface of this topic, there is great potential in machine learning and artificial intelligence applied with aquaculture and fish farm systems. We wanted to ask leading industry experts Matt Clarke of Poseidon Ocean Systems, ...

floating fish feeds vs sinking feed pellets
Generally there is no nutritional difference between floating and sinking feed. Advantages of floating feed • High Nutrition Retention • Environment-friendly • Easy to Store • Best for a Young Fish Breed • Monitoring the fish Advantages of sinking feed • Better for fish who likes to live in bottom level of water. • Great for sky or pavid fish that are scared ...

Choose the Suitable Fish Feed Pellet
The cost of fish feed accounts for a large proportion of the coast produced by fish farmers. Feed pellets are widely used in fish farming. Choosing only the right quality fish feed particles can improve feed utilization, growth rate and immune system, and prevent disease. Therefore, fish farmers must learn how to choose the right fish feed pellets. First, the nutrition of fish feed. The basic ...

Underwater Unmanned Aerial Vehicle-Future of Marine Fisheries
First of all, there is huge market space for underwater drone. In terms of Fisheries and aquaculture, China's aquaculture area is 8465,000 hectares, of which 27.38% is mariculture area and 72.62% is freshwater aquaculture area. There are 32,000 aquaculture farms in China, covering an area of 10 million hectares. It is necessary to check the temperature, salinity, PH value, dissolved oxygen of ...

Transgenic fish are ready for us. Are we ready for them?
After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of ...

Anti‐anxiety drugs and fish behaviour: Establishing the link between internal concentrations of oxazepam and behavioural effects
Psychoactive drugs are frequently detected in the aquatic environment. The evolutionary conservation of the molecular targets of these drugs in fish suggest that they may elicit mode‐of‐action mediated effects in fish as they do in humans, and one the key open question is at what exposure concentrations these effects might occur. In the present study, we investigated the uptake and tissue ...

Drying Sardine Fishes by Microwave Drying Machine
1. Why Fresh Sardine Fishes Need to Be Dried by Microwave Drying Machine? Sardine fish is an important source of high-quality protein required in human diet, but it has not yet been fully utilized, due to the limited storage period and, sometimes, their strong fishy odor. Fresh sardine fish contains up to 80% of water, and it is a highly perishable material and having a short storage life. ...

Bioaccumulation of decamethylpentacyclosiloxane (D5): A review
Decamethylpentacyclosiloxane (D5) is a widely used, high–production volume personal care product with an octanol–water partition coefficient (log KOW) of 8.09. Because of D5's high KOW and widespread use, it is subject to bioaccumulation assessments in many countries. The present study provides a compilation and an in‐depth, independent review of bioaccumulation studies involving D5. The ...

Forecasting fish biomasses, densities, productions, and bioaccumulation potentials of Mid‐Atlantic wadeable streams
Regional fishery conditions of Mid‐Atlantic wadeable streams in the eastern United States are estimated using the BASS bioaccumulation and fish community model and data collected by the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP). Average annual biomasses and population densities and annual productions are estimated for 352 randomly selected ...

Development of an adaptive monitoring framework for long‐term programs: An example using indicators of fish health
Detecting unwanted changes associated with localized human activities in aquatic ecosystems requires defining the value of an indicator expected at a site in the absence of development. Ideally, adequate and comparable baseline data will be collected at an exposure location prior to that development, but this is rarely done. Instead, comparisons are made using various designs to overcome the ...

Incidence of Aeromonas species isolated from water and fish sources of Lake Manzala in Egypt
Lake Manzala situated in the east of Nile Delta, between the Damietta branch of Nile River and Suez Canal. The lake receives pollution from different sources, which make the lake polluted and eutrophicated. Samples were taken from five sites of the lake. Faecal coliforms showed the highest counts 2.2× 10 3 cfu ml –1 and 4× 10 3 cfu ml –1 in water in El-Kapoty and El-Mataryia areas, ...

Threshold‐dependent sample sizes for selenium assessment with stream fish tissue
Natural resource managers are developing assessments of selenium (Se) contamination in freshwater ecosystems based on fish tissue concentrations. We evaluated the effects of sample size (i.e., number of fish per site) on the probability of correctly detecting mean whole‐body Se values above a range of potential management thresholds. We modeled Se concentrations as gamma distributions with ...

Effects of anionic polyacrylamide products on gill histopathology in juvenile rainbow trout (Oncorhynchus mykiss)
Anionic polyacrylamide (PAM) products are commonly used to remove suspended materials from turbid waters and to help mitigate soil erosion. In the present study, juvenile rainbow trout (Oncorhynchus mykiss) were exposed to between 3 to 300 mg/L of ten commercially available PAMS (Clearflow Water Lynx Polymer Log and Clearflow Soil Lynx Granular Polymer; Clearflow Enviro Systems Group Inc.) and ...

Wreck Removal - Palymyra Atoll - Case Study
In the summer of 1991,a 121 foot long Taiwanese long line fishing vessel, the HUI FENG #1, ran aground on an atoll in the middle of the Pacific. With a footprint of just 4.6 square miles Palmyra Atoll forms the most northern vegetated island in the Northern Line Islands, lying some 1,000 miles south of Honolulu. The atoll has a long storied past and is now a national monument and wildlife ...

Investigating Alternatives to the fish early‐life stage test: A strategy for discovering and annotating adverse outcome pathways for early fish development
The fish early‐life stage (FELS) test (Organisation for Economic Co‐operation and Development [OECD] test guideline 210) is the primary test used internationally to estimate chronic fish toxicity in support of ecological risk assessments and chemical management programs. As part of an ongoing effort to develop efficient and cost‐effective alternatives to the FELS test, there is a need to ...
