Commercial Aquaponics Production and Profitability
The purpose of this research by David C. Love et al, Johns Hopkins University, US, was to document the production methods, crop and fish yields, and profitability of commercial aquaponics in the United States (US) and internationally. ...
Mosquitofish Genitalia Change Rapidly Due to Human Impacts
Half-century-old roads connecting portions of Bahamian islands while fragmenting the tidal waters below – leads to rapid and interesting changes in the fish living in those fragmented sections, according to a new study from North Carolina State University....
Assessing Aquaculture Sustainability: A Comparative Methodology
Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development...
Examining Gelatinized and Non-gelatinized Corn Starch Based Diets in Rohu Carp
Labeo rohita may be able to utilize the non-gelatinized corn starch based diet more efficiently and being economical it spares the protein based cost effective feed, according to research by Mahwish Qamer et al, University Faisalabad, Pakistan....
Aquaculture and Organic Aquaculture in Turkey
Organic aquaculture has been implemented in Turkey since 2010. As organic aquaculture represents a new practice area and sufficient promotional efforts and governmental support is not available, satisfactory levels have not been achieved yet in this sector....
New Aspect in Cartilage Growth “The Invasive Interstitial Type”
Growth of hyaline cartilage is achieved either by chondrocyte division “interstitial type of growth” or by perichondrial cell differentiation of mesenchymal cells to differentiated chondrocytes which deposit successive circumferential layers of cartilage...
Practical Supplementation of Shrimp and Fish Feeds with Crystalline Amino Acids
Fish meal has historically been the protein source of choice in aquatic feeds, but global supplies have reached a plateau making it less available and more expensive. As a consequence, the use of cheaper proteins made from processed plant proteins, byproducts...
Engineering or Food? Mechanisms of Facilitation by a Habitat-Forming Invasive Seaweed
Nonnative species that form novel habitats strongly affect ecosystem processes. The effects of these ecosystem engineers can be both positive and negative but the mechanisms behind their effects are not well described. In this study Jeffrey T. Wright...
Replacement of Fishmeal with Microalgae on Common Carp Weight Gain, Meat, Composition and Survival
The use of blue green algae Spirulina in aquaculture has several potential advantages over the production of fish, writes Nasreen M. Abdulrahman and Hawkar J. Hamad Ameen, University of Sulaimaniya....
Use Of Ulva Lactuca Studied In White Shrimp Diets
Research conducted by Susan Laramore et al, Harbor Branch Oceanographic Institute at Florida Atlantic University, studied whether fresh U. lactuca harvested weekly from a land-based integrated multi-trophic aquaculture system could be utilized as a...
Probiotics for Health Management in Aquaculture
Aquatic animals have a much closer relationship to their external environment than terrestrial animals and are thus more susceptible to pathogens in their environment....
Stickleback Fish Dads Influence Offspring Behaviour and Gene Expression
Researchers report that some stickleback fish fathers can have long-term effects on the behavior of their offspring. The most attentive fish dads cause their offspring to behave in a way that makes them less susceptible to predators. These behavioral...
When Is Spillover from Marine Reserves Likely to Benefit Fisheries?
The net movement of individuals from marine reserves to the remaining fishing grounds is known as spillover and is frequently used to promote reserves to fishers on the grounds that it will benefit fisheries. Here Colin D. Buxton et al, University of...
AQUAPLAN 2014-2019 - Australia's National Strategic Plan for Aquatic Animal Health
AQUAPLAN 2014–2019 is Australia’s third national strategic plan for aquatic animal health. It outlines the priorities to strengthen Australia’s arrangements for managing aquatic animal health, and to support sustainability, productivity, and market...
Profitable Sustainability in Aquaculture
Consumer awareness of sustainable aquaculture production has led to increased interest in certification for sustainable aquaculture practices. In contrast to common belief, this certification encompasses a broader scope than just environmental issues....
