    Characterization of lignocellulolytic activities from fungi isolated from the deep-sea sponge Stelletta normani por Balestrini, Raffaella, Batista García, Ramón Alberto, Sutton, Thomas, Jackson, Stephen A., Tovar Herrera, Omar Eduardo, Balcázar López, Edgar, Sánchez Carbente, María del Rayo, Sánchez Reyes, Ayixon, Dobson, Alan D. W., Folch Mallol, Jorge Luis

    Publicado 2017
    “…The deep sea can be considered an extreme habitat due to low temperatures (<5ÊC) and high pressure, however marine sponges survive in these habitats. While bacteria derived from deep-sea marine sponges have been studied, much less information is available on fungal biodiversity associated with these sponges. …”

    The use of immune-stimulants in fish and shellfish feeds por Raa, Jan

    Publicado 2019
    “…Such substances may also, but not necessarily, render animals more resistant to infectiousdiseases and reduce the risk of disease outbreaks if administrated prior to situations known to result instress and impaired general performance (e.g. handling, change of temperature and environment,weaning of larvae to artificial feeds) or prior to expected increase in exposure to pathogenic microorganismsand parasites (e.g. spring and autumn blooms in the marine environment, high stockingdensity). In addition, aquaculture may benefit from the use of such immune-stimulants when they areused prior to, and during, developmental phases when the organisms are particularly susceptible toinfectious agents (e.g. the larvae phase of shrimp and marine fish, smoltification in salmon, sexualmaturation). …”

    Global Trends in Aquaculture and Feed Ingredient Use in Compound Aquafeeds por J. Tacon, Albert G.

    Publicado 2013
    “…By region, Asia accounted for over 91.2 percent of total global aquaculture production in 2011 (APR 8.46 percent since 1984), followed by the Americas at 3.53 percent (APR 7.59 percent), Europe at 3.20 percent (APR 3.99 percent), Africa at 1.84 percent (APR 14.82 percent), and Oceania at 0.25 percent (APR 9.02 percent).In terms of the major farmed species groups in 2011, finfish accounted for 41.6 million tonnes or 49.8 percent of total global aquaculture production in 2011 (valued at US $ 83.6 billion, with over 102 reported fish species, and production growing at an average APR of 8.85 percent since 1984), followed by aquatic plants at 21.0 million tonnes or 25.1% of total global production (valued at US $ 5.5 billion, with 12 reported aquatic plant species, and production growing at an average APR of 7.16 percent since 1984), molluscs at 14.4 million tonnes or 17.2 percent of total global production (valued at US $ 15.3 billion, with 27 reported mollusk species, and production growing at an average APR of 7.17 percent since 1984), and crustaceans at 5.9 million tonnes or 7.0 percent of total global production (valued at US $ 28.4 billion, with 15 reported crustacean species, and production growing at an average APR 13.1 percent since 1984; FAO, 2013).The total production of the major finfish and crustacean species groups fed industrially compounded or farm-made aquafeeds was reported to be 40.57 million tonnes in 2011 (FAO, 2013), with total global industrial compound aquafeed production estimated at approximately 35.75 million tonnes; the major compound feed fed species groups including: Chinese carp at 11.76 million tonnes (excluding silver carp and big head carp) with an estimated total compound aquafeed requirement of 10.19 million tonnes; Tilapia at 3.96 million tonnes with an estimated total compound aquafeed requirement of 5.79 million tonnes or 16.2 percent of total global compound aquafeed production;Shrimp at 3.93 million tonnes with an estimated total compound feed requirement of 5.54 million tonnes or 15.5 percent of total global compound aquafeed production; Catfish at 3.38 million tonnes with an estimated total compound feed requirement of 3.70 million tonnes or 10.3 percent of total global compound aquafeed production; Marine fish at 2.01 million tonnes with an estimated total compound feed requirement of 2.82 million tonnes or 7.9 percent of total global compound aquafeed production; Other freshwater and diadromous fish at 1.94 million tonnes with an estimated total compound feed requirement of 1.24 million tonnes or 3.5 percent of total global compound aquafeed production; Salmon at 1.93 million tonnes with an estimated total compound feed requirement of 2.51 million tonnes or 7.0 percent of total global compound aquafeed production; Freshwater crustaceans at 1.67 million tonnes with an estimated total compound feed requirement of 1.71 million tonnes or 4.8 percent of total global compound aquafeed production; Milkfish at 891,407 tonnes with an estimated total compound feed requirement of 820,000 tonnes or 2.3 percent of total global compound aquafeed production; Trout at 791,959 tonnes with an estimated total compound feed requirement of 1.03 million tonnes or 2.9 percent of total global compound aquafeed production; Eel at 255,284 tonnes with an estimated total compound feed requirement of 392,000 tonnes or 1.1 percent of total global compound aquafeed production in 2011.In terms of feed ingredient usage, the compound aquafeed sector still remains the largest consumer of fishmeal and fish oil, aquaculture consuming 78 percent of total global fish oil production in 2011 (major aquaculture species group consumer being salmonids at 66 percent followed by marine fish at 17 percent) and 68% of total global fishmeal production in 2011 (major aquaculture species group consumer being crustaceans at 30 percent, followed by salmonids at 22 percent, and marine fish at 21 percent; Dr Andrew Jackson, personal communication, The Marine Ingredients Organization, http://iffo.net). …”

    Electrochemical Evaluation of Reinforcement Concrete Exposed to Soil Type SP Contaminated with Sulphates por Santiago Hurtado, Griselda

    Publicado 2016
    “…The present research evaluates the electrochemical behaviour of concrete exposed to SP soil type, sand from marine environment and contaminated with 1, 2 and 3 % de MgSO4, this experimental setup simulates what happens on the foundations of civil infrastructure as bridges, docks, highways, etc., when they are built on contaminated soils with this aggressive agent due to discharges of wastewater, marine waters or areas polluted by agrochemicals. …”
