Aiyo, how many fries and young fish died in my hands ...
at least ah lau got a decent looking fish from his 22 of them. not bad liao. when i do culling, 1 in a 1000 can make in to next round, worst then Superstar leh.

Ya man... CP is very very lucky...

At least you still have 1 good one in 1000. I have tried two times at P1 level only and have to accept one unwillingly for keeping purpose. I find that if you match 2 different lineages of SVR, deformity rate is as high as 60%.

I would like to expand on the subject purported by cp on the development of fish and the classification of fish development by virtue of its sizes. Far too often we may subscribe to this belief and degrade a particular fish if we do not recognize another cause of concern and that is feeding behaviors.

Fish feed at different levels and food are formulated to suit their specific needs. Surface feeders, mid level feeders and bottom feeders are broad spectrum classification base on the nature of feeding and dwelling of respective species.
Generally speaking goldfish has the luxury to belong to all levels though the evolution of their mouth parts tend to yearn towards bottom feeders or browser like carps.

By the power of your observation, I believe if you have a keen eye, you would have recognized some behavioral feeding pattern why some fish lack behind in terms of development apart from genetics.This fish I call them as JIU CHENG(wo wo) or PAH JIAU.

From my personal experience I have pick up some poor feeders which have shown poor competitive skill to feed well, missing food thrown at all levels. We tend to succumb into giving extra more feed to benefit these born losers but ultimately overfeeding the more dominant siblings/occupants.Unable to compete against its more aggressive counterparts,this fish tend to develop poorly despite sharing all the same environment and enjoying the same luxury of space and water management.I think to harness its potential,this has to be recognized early ,isolate and,feed them separately in order to nurture them to their ultimate potential .
Just like an experienced educator being able to pick up slow and lacking learners among a cohort, we as keepers should exercise prudence in recognizing weak and slow developers and give these the extra attention to realize their potentials .It is not my intention to contradict cp’s inference but I rather view it as a complement to his excellent article on fish development with my supplementary findings.

As for my case, in my observation during the morning and evening feeds, all 22 fishes consume more or less the same amount of feed.All start and finish at the same time.There are no fast or slow feeders.

I conclude that their growth are already predetermined genetically.

Yes, my friend, you just hit the G spot.

hello CP,

I am not sure about your comment about commercial selling pattern.
But for me, I won't pay more because of bigger size. And I agree with white horse's statement.

But I think if the more knowledgable a hobbyist is, the tougher the commercial trade will have to work for your money. Of course, the knowledge must be valid, not just by listening.

Namaste

A futher update on the disparity in sizes of the FH,FM,FT phenomena:

Here's the size difference in Sept 05:

And here's how different they are today(pic taken 12 May 06):

And the smallest:




The many different sizes from a same spawn,same feeding,same water parameters,same upbringing conditions:
