Uk cold water rock pool

[Subsea]

@Nman
In September, I received 100 Blue Tilapia fingerlings which were introduced to six different outdoor fresh water tubs; in ground tanks ranging from 150G - 1500G. A 30G glass tank outdoors with an air stone & heater was also set up outdoors; Blue Israeli Tilapia can withstand lower 50 degrees for a short time. Because Blue Tilapia can breed in full strength ocean, I added 1G of partial change water from reef tanks indoors. In addittion to this source of nutrition, I feed flakes to fingerlings. Due to inattention on my part, evaporation continued raising salinity to 40ppt with dead tilapia and green water. Because a sustainable source of phytoplankton is more time critical for me, I will adjust tilapia to salt water at another time. Next time I will use young adult tilapia for salt water conversion.

@Subsea My outside tub is sat at 11 c fish and inverts and anemones seem too be doing great oh and the crab and shrimps. I don’t know when low temperature is too cold I was thinking 4c but I don’t really know. I am not running a heater only a filter . Food the blennys are eating
mysis flake brine shrimp mussel and I am going to try limpets chopped up. They might eat them if so there are plenty of them . Sea weed is still alive and staying alive but not much growth this could be to do with temperature lighting or iron needs dosed but most seaweeds get there growth through light. Just something I will have to keep trying and learning I like tanks with sea weed in them they then look natural

they we're all over in the beach in newcastle litrally all over the rocks everywhere
idk about now as they are currently dumping loads of RAW sewage in the beaches in newcastle crustations dead all over the sand

Yep they want done for it . But they won’t get anything done maybe fine . But if we take a pebble off the beach it’s against the law it’s a bit of a joke imo

i always thought we we're allowed to take stuff from beaches in the UK has that always been a law cause i use to take sand/crabs home all the time when i was younger

What kind of seaweed in that tub? What kind of seaweed can you collect in cold water of the North Sea?

All my stuff is Caribbean / Gulf of Mexico. Yesterday, I was watching a podcast from a commercial seaweed farm in Pacific Northwest coast of Organ where they grow an ediable seaweed, Dulse. This morning when I did a goggle search, the first link was a seaweed farm in the Northeast on the coast of Maine.

Wild Atlantic Dulse - Nutritious Red Seaweed for Delicious and Healthy Cooking

Dulse available in leaf, granule, flake, and powder forms from Maine Coast Sea Vegetables

PS: TASTE LIKE BACON

Subsea I know sea lettuce grows fine in tanks but very delicate and can tear and the shrimps love it . Gutt weed grows well in the tanks they both a green sea weeds so now for brown or red seaweeds Irish moss sort seaweed doesn’t do much also serated wrack looks good but struggle’s in the tank . And I have a seaweed that clings on too other seaweeds and grows from there very feathery appearance

There trying too protect everything as you know but I just lets say go for a walk along the beach . No a new law if you Google beach laws oh it’s a joke

For GulfCoast livestock, I would say 50 degrees is lethal for fish. I will set heaters to come on at 60 degrees falling. For mineral makeup, I use liquid seaweed concentrate. Extra iron can not hurt.

So now, 30G tilapia conversion tank is a source of phytopkankton which is more valuable to me than tilapia janitors in salt water.

@Subsea have you got all the does and don't on outside plankton setup and how you exactly set it up please. I am going to do the same. Thanks nman

I just feed 2G of live phytoplankton from outdoor 30G phyto growout tank into fishless 30G mixed garden heavy on red macro and mixed inverts including flame scallop, sea apple, as well as ornamental sponges and a cannister filter as a hiflow cryptic refugium. The janitors in this tank include amphipods, copepods, snails, emerald crabs and bristle worms.

Looks good subsea

With respect to outdoor phytoplankton cultivation, it happened accidentally. I used partial water change water from several systems to setup Tilapia salt water conversion tank.

I feed tilapia heavy and once I saw phytoplankton growing, I added liquid seaweed concentrate:

If you like mussels and star fish this is for you

Not sure what notification I missed, but was out for a month.

Thinking of changing my dentist he’s told me my teeth were lovely .

Lovely meaning profitable.
