Live transport of the green sea urchin in air and immersed in seawater and the impact on subsequent roe enhancement after in-water transport
Philip James; Tor Evensen http://doi.org/10.1111/are.16004 ABSTRACT The roe enhancement of sea urchins from barrens requires suitable transport techniques to enable transport of live sea urchins to enhancement facilities. For the green sea urchin Strongylocentrotus droebachiensis, the maximum period that the ‘out of water’ techniques described in this manuscript could be used is temperature dependent. When transported at 3.0°C, this should…
Biofloc removal by the oyster Crassostrea gasar as a candidate species to an IMTA system with the marine shrimp Litopenaeus vannamei
L´ea Carolina de Oliveira Costa; Luis Henrique da Silva Poersch; Paulo Cesar Abreu https://www.sciencedirect.com/science/article/pii/S0044848621003938 ABSTRACT: Currently, aquaculture seeks to implement production models that keep up with the global demands for sustainability and reduced environmental impacts. One of the options adopted is integrated multi-trophic aquaculture (IMTA), which cultivates species of different trophic levels, improving the use of nutrients and increasing the…
Comparison of the growth of Saccharina latissima at a cultivated natural area and an aquaculture site in Sørvágsfjørður, Faroe Islands
Mayleen Schlund https://zenodo.org/record/6563042#.Ys6d6sVByUk Abstract The aim of this thesis was to assess the growth difference of the seaweed species Saccharina latissima at an Integrated Multi-Trophic-Aquaculture (IMTA) site compared to a reference site without fish cultivation in Sørvágsfjørður, Faroe Islands. Therefore, one growth season of S. latissima, CTD data and nutrient parameter (nitrate, ammonium, phosphate, silicate) were analysed. The seasonal temperature…
Effects of Microalgae Addition and Fish Feed Supplementation in the Integrated Rearing of Pacific White Shrimp and Nile Tilapia Using Biofloc Technology
Vitor F. Silva, Patriula K. M. Pereira, Mateus A. Martins, Marco A. d. Lorenzo, Herculano Cella, Rafael G. Lopes, Roberto B. Derner, Paola Magallón-Servín and Felipe do Nascimento Vieira https://zenodo.org/record/6497812#.Ys0y9cVByUl Abstract This study aimed to evaluate a Pacific white shrimp and Nile tilapia integrated system using biofloc technology with or without the addition of the microalgae Scenedesmus obliquus and with…
Defining Nature-Based Solutions Within the Blue Economy: The Example of Aquaculture
Adam D. Hughes https://doi.org/10.1016/j.jclepro.2020.123873 Policy brief article The concepts of Nature-based Solutions (NbS) and the Blue Economy (BE) are two prominent sustainability frameworks at the forefront of policy dialogues. However, investment within the BE has been slowed by the lack of a sufficiently robust operational definition. This lack of definition reduces investor confidence and impacts adoption by policy makers and...
Cultivation of the seaweed Ulva spp. With effluent from a shrimp Biofloc rearing system: different species and stocking density
Mateus Aranha Martins, Vitor Fernandes da Silva, Patricio René Tarapuez, Leila Hayashi, Felipe do Nascimento Vieira https://www.pesca.sp.gov.br/boletim/index.php/bip/article/view/1568/1476 Abstract This work evaluated the use of effluent from a marine shrimp biofloc rearing system to cultivate two species of the green seaweed of the genus Ulva. First, the growth of two Ulva species, U. ohnoi and U. fasciata, was evaluated. Second, the...
Nannochloropsis spp. as Feed Additive for the Pacific White Shrimp: Effect on Midgut Microbiology, Thermal Shock Resistance and Immunology
Ariane Martins Guimarães, Cristhiane Guertler, Gabriella do Vale Pereira, Jaqueline da Rosa Coelho, Priscila Costa Rezende, Renata Oselame Nóbrega, Felipe do Nascimento Vieira https://doi.org/10.1016/j.aqrep.2020.100479 Abstract The biofloc culture system (BFT) allows for the production of aquatic animals at higher stocking densities compared to conventional aquaculture systems and it has been proven to be efficient for shrimp (Litopenaeus vannamei) and mullet...
Evidence of total suspended solids control by Mugil liza reared in an integrated system with pacific white shrimp Litopenaeus vannamei using biofloc technology
Mariana Holanda, Gabriel Santana, Plinio Furtado, Ricardo Vieira Rodrigues, Vinícius Ronzani Cerqueira, Luís André Sampaio, Wilson Wasielesky Jr., Luis Henrique Poersch https://doi.org/10.3390/ani11010150 Abstract This work aimed to evaluate Nannochloropsis spp. as feed additive in the diet of Pacific white shrimp for their effect on midgut microbiology, thermal shock resistance and immunological parameters. Initially, the digestibility of the microalgae meal was...
Assessing the impact of bivalve aquaculture on the carbon circular economy
A.A. Alonso, X. A. Álvarez-Salgado, L. T. Antelo https://doi.org/10.1016/j.jclepro.2020.123873 Abstract Global production of shell calcium carbonate (CaCO3) from bivalve aquaculture amounts about 13.6 million metric tons per year. Shells, traditionally considered a waste of aquaculture activities, have recently acquired an interest under the current framework of zero waste circular economy. Shell CaCO3 is a sustainable biomaterial that could partly replace...
