I may make a note here and there, but, mostly, I purloined this article upon which I stumbled. I have left all of the attributions in so you know who the guilty parties are.

I am not sure if I approve of this genetic modification. Generally, I support reasonable genetic playing around, after all, all advances in agriculture and animal husbandry resulted from controlling the reproductive process of whatever was being manipulated. Jacob did this to his father-in-law to insure the goats and sheep he got to keep were the ones likely to be borne. I believe that was based on color. I forget who I studied about as a kid, but, I still recall the controlling of which peas got to fertilize the other peas led to the development of better peas. I have over 250 named varieties of day-lilies many of which are triploids, you got it, genetically modified plants and beautiful! Slaves, sadly, were bred for strength. Commenting on this fact caused Jimmy the Greek his job when he discussed the link between the prevalence of blacks in football and the foul habits of slave owners to breed their slaves for desired characteristics. You and I picked our brides and grooms based on certain genetic traits we found attractive. So, fiddling with genetics is not new. But, when you start using technology, we start to get nervous. Maybe with good reason. Somehow, Arnie the trout bothers me. I look at this body and do not see muscles, I see tumors. Finely developed bodies are pleasant to look at. This goes for human and animal. This fish does not turn me on! What do you think?

Meet Arnie, the Terminator Trout with the physique of a body-builder

Scientists have created a genetically-modified trout with the rippling muscles of a body-builder.

The mutant fish is the result of a decade-long effort by Terry Bradley, a professor of fisheries and aquaculture at the University of Rhode Island.

The rainbow trout’s enhanced muscle mass is between 15 to 20 per cent higher than that of a standard fish, thanks to Professor Bradley’s research into the inhibition of myostatin, a protein that slows growth.

The increased muscle mass will have commercial benefits in that larger fish can be grown without increasing the amount of food they need.

While the physical differences in the fish include a prominent dorsal hump, making it look as if it has muscular shoulders, and the appearance of ‘six pack abs’, no differences in behavior have been noted.

Describing the results as ‘stunning’, Professor Bradley told Science Daily: ‘Belgian blue cattle have a natural mutation in myostatin causing a 20 to 25 percent increase in muscle mass, and mice overexpressing myostatin exhibit a two-fold increase in skeletal muscle mass.

‘But fish have a very different mechanism of muscle growth than mammals, so we weren’t certain it was going to work.’

Luckily for Professor Bradley, it did work.

The team injected thousands of rainbow trout eggs with various DNA types designed to inhibit myostatin.

Of the eggs that hatched, those which carried the gene began to develop ‘body-builder’ physiques.

Professor Bradley added: ‘The results have significant implications for commercial aquaculture and provide completely novel information on the mechanisms of fish growth.

‘The results also allow for comparisons between the mechanisms of growth of muscle in mammals versus fish, and it could shed light on muscle wasting diseases in humans.’
