While we have already harvested our F4 generation Royal Blue xbacks some years ago, we only harvested our F4 generation Sapphire Gold xbacks today. F3 brooders were placed in the mud ponds in the year 2002 and they are now already 4 years old, a ripe age for adult xbacks to start to hold their eggs well.
Selection criterion for these F3 brooders were based on the following factors - good gold intensity, high base colour contrast, spoon head, sissors bite mouth, and golden head features. Due to these stringent requirements, not more than a hundred fishes made the grade. But we are still very happy that they have started to reproduce their offsprings and am really looking forward to seeing the growth of these fry in the next 4-5 months.
Have a good time reviewing these uncensored pictures, taken using sequential shots.
虽然我们已于几年前收获了我们的F4 世代皇室蓝过背金, 我们只在今天收获了我们的F4 世代蓝宝石紫蓝底过背金。 F3的种鱼已经早在2002 年被安置了在泥池塘里栽培，而且他们现在已经4 岁, 到达 一个可以开始孵好蛋的成熟年龄. 选择这些F3种鱼标准是根据以下因素- 重金质感、高底色对比、 汤匙头、吻合嘴 和头顶带金黄线/金黄块的特点。由于这些要求较高, 能够令人满意的F3种鱼不超过一百条。 尽管如此， 因为它们此刻已经开始生产他们的子孙后代，我们仍然感到非常愉快。同时，我们也很盼望看到它们 在未来4-5 个月内的成长。
