I went out of my way to tame this for black pearls but I realized my 140% apprentice pickaxe gathers slightly more than the angler even though I pumped points into melee.
An angler combined with a flying tame is the best way to get silica pearls to your base, take a flying tame with lots of weight when you are collecting silica pears, when you're done dump all the pearls into your flier and fly back to your base
