..from this report from Natural Shrimp.
Some general information about vibrio and a) biofloc process is not ubiquitous at all where the major shrimp growing is done to satisfy commodity markets b) vibrio is also found in the sea so should there be concern to go swimming c) Taiwan shrimp industry collapsed due to vibrio well point infection – maybe a good pre filter technology for shrimp hatcheries also? Or does chlorine and thiosulphate work just as well?
Unsure exactly what the sell is – surely it should be the shrimp harvest as the profit? There are plenty of treatment processes being offered by RAS and equipment companies. From mechanical, chemical, biological, electrical (pulsed ozone, UV, cold plasma).
For God’s sake sell the frigging shrimp guys. I tried to buy the shrimp from Medina del Campo here in Spain over Internet but did not work….
I remember in the 1970’s swimming off Monaco where floating human feces was our major problem. You had to water ski around the shit. The Oceanographic Institute in Monaco released an exotic seaweed accidentally into the sea when cleaning out a tank back then.
In the 1980’s vibrio was also common. Sea urchins were carriers. Offshore boats were collecting the seaweed every year for decades from the release – not plastics! Talk about near shore beach cleanups. Tourism and all that…
In the UK in the 1970’s children were receiving police in all schools as the Dangerous Litter act went from £10 to £100. Celebrities were used in the Keep Britain Tidy – Tidyman campaign. It was very public and children got involved – it was a jolt for Baby Boomer families because that education led to children shaming adults…….even in public………..shame is more that world did not learn faster.
Generation X parents were not all on board yet its only from Millennial on that there was 100% on boarding – but by then their near environment was well covered.
Fast forward to 2019. Most ocean plastic wastes come from just 10 rivers and countries where education requires bolstering. Yes this is already a generation behind with regards to the cardinal sin of littering….
At the beach this year got to see 18 year old French girls doing this. These are now considered post-millennial under latest guidelines from Pew research…..but get this…
……my daughters, yes my daughters, at 12 years old, have a friend who is competing as Spanish representative in JESC – Junior Eurovision song contest. She went to the beach to do the video on saving the Oceans and plastics and all that good stuff….but guess what….my daughters say they could not find any plastic on the beach and had to take some with them for the shoot!
Well done Spain.
Good luck Melani in Poland for November….
Desalination and filtration is oft used in shrimp processing facilities and freshwater is also required in hatcheries.
As always water technology to do with marine environments is important in the shrimp industry.
BBC News – Temperature maps from space would ‘boost crop production’
What – EU does not have this already in place? Or is this a fund raising exercise?
Back in the 1980s and in South America we had access to NASA satellite pictures of our shrimp ponds in Ecuador. Idea was to use color and heat signature of 30 hectare ponds to calculate water/feed requirements – with feeding by modified crop duster plane and water exchange capabilities for pond algal growth.
It was too expensive and anyway better to have on ground analysis for rapid response – especially in proactive preventative pond culture husbandry. Yes shrimp farming was about growing and maintaining algal blooms in those days and efficiencies on fertilizers and water exchanges. Uneaten feed acted as fertilizer as well.
This UK announce project seems to be using NASA technology also.
With the advent of agTech localized drones I wonder if this is really necessary for crop production and management.
Biofilms are an emerging issue in shrimp processing and in production systems. They can harbor antimicrobial resistant (AMR) bacteria. Methods to control and eradicate need to be looked at.
Harvesting shrimp in the old days meant getting down and dirty pond side. Rostra punctures and cuts were the norm. These would rapidly get staph infected and workers would wipe eyes, transfer infection etc.
My cure was garlic to clean cuts. But many use chloramphenicol as cheap and very effective. Of course plastic eye drop bottles get chucked….!
Farm HR protocols may not be tight in that aspect of supporting workers in hazardous jobs. Would be interesting to see what standards policies are….
Blue light might work also somewhere in chain…
