Can a foreign expert successfully fish for a deep-sea giant using a squid weighing tens of kilograms?

This young man's fishing method is utterly ridiculous—he grabbed a giant squid weighing over forty pounds and threaded it directly onto the hook as bait He promptly tossed it into the sea and the massive squid slowly sank into the deep ocean To keep the vessel stable heaved two large stones into the water as anchors Several minutes passed the screen on the trolling lure displayed "known squid bite" yet he felt no strong pull After sensing something was wrong he quickly hauled the squid up—sure enough as expected the creature had been violently torn apart on the seafloor its head completely bitten off Its tail was also severely damaged The young man immediately realized the squid must have been too large The big fish couldn't fit in his mouth Then he pulled out a ten-pound squid Throw it back into the sea and try again—this squid is still lively Once submerged it keeps darting deeper into the ocean which attracts the attention of larger fish more effectively The fishing rod suddenly jerked with tremendous force as the line tightened and a marlin burst out of the water its temper as fierce as its speed This marlin looks to weigh around sixty or seventy catties with similar bite wounds on its body indicating there's an even larger fish in the water The young man immediately cuts off the fish's head Tossed back into the water as bait the fishing rod soon twitched again—upon closer inspection another swordfish had taken the hook though this one was significantly smaller The young man effortlessly hooked the fish onto the boat The fish appeared to weigh about 40 catties Clearly it wasn't the giant monster fish he'd been searching for Although today didn't bring the result he'd hoped for catching two swordfish was quite a pleasant surprise
