Thinking too much ?

Having noticed some fish that can move between salt and fresh water eg mullet and bass, does this mean for instance that i could keep macks in an areated tank instead of gold fish????? In other words can all fish make this move can rainbows exist in salt water for instance or pollack move into fresh.

the title is right ur thinking too much

most fish can withstand a slight increase or reduction in salinity, but only for short periods of time, after that they become dehydrated, the main difference between saltwater and fresh water fish is the way they asorb water. so obviously a bass in a mill pond is going to get thirsty. somefish can do extended periods of time such as salmon and to a lesser degree mullet. they have certain mechanisms that deal with metabolic absorbtion and excretion that can be adjusted depending on the enviroment. but even this must happen gradully, an instant change in the slinity of water will kill all fish.

brown trout can live in saltwatwer water they then turn into sea trout.

Think they're completely different species

A brown trout that moves to a tidal estuary becomes a slob trout I think, you might be getting mixed up!

some brown trout will move to a rivers estuary and their appearance changes over time, they then look very similar to seatrout, they are then called Drock'en/slob/estuary trout.(people have their own name for them), they will move in and out of the river on each tide, i catch a lot of these trout every year and they can put up a very good scrap

Kept a flounder alive overnight in my bath once to return it after weighing!

Nope- they are the same species.

Something lost forever somewhere in the haze inside my head remembers from my childhood something about eels migrating to the Sargasso Sea, is that fresh water eels or is it some myth that I remember half hearing about way back in my school days

nope its true

did i read in another post on the site that pike can be found in rivers estuary some times?

salmon dont eat when they return to freshwater, seatrout and brown are the same species, just live in different areas, sliver eels can live in the sea but you usally find them close to a river, mullet and bass can feed/live in brackish water but for a short time, some sea fish dont go near freshwater as it kills them. There is one sea fish that i and many others have caught miles upriver from the sea, and are known to be able to live in fresh, brackish and sea water, the humble flounder

Apparently the humble flounder has been caught in Lough Neagh down near Ballyronan i beleive.

Years ago I had a caravan in East Cork next to Inch beach. All the flounder that were caught during a session were put into a stream that flowed in to it the beach. The next morning I’d go down and there would be some still is there alive and kicking. I never found a dead flounder as for dogfish done the same thing once zero success.

As a young lad I caught dabs behind the old greyhound track in the Western Rd. in Cork. For those not in the know it’s the channel that pass UCC.

To top that in the old days of the “weigh-in” system I had a specimen Painted Ray at a competition in Garryvoe. When I got home I put the fish in to the sink to wash it and gut it. Once the water flowed over the ray it showed signs of life. I put water in the bath and a full carton of table salt. The next morning the ray was wrapped in wet towels, taken down to Monkstown pier where it swam away.

Ok i was thinking to much then great replies theres some great stories hidden away in peoples heads me thinks

found the article about pike in saltwater http://www.esoxhunter.com/SaltyPike.php
