South American Silver Porgy (Diplodus Argenteus) Description

The South American Silver Porgy, as its name states, is a silver-colored fish. Their most distinctive feature is the little black spot at the base of their tail.

A South American Silver Porgy has a small lump in between its eyes. Their dorsal and anal fins are also quite short and appear to be folded into the body. The fins of the South American Silver Porgy appear to be made of soft spines. Its fins appear to be translucent but it has bright gold highlights at the tip. Its pectoral fins however appear to be more of transparent golden-yellow color. The tail fin of a South American Silver Porgy has a deep “v” that splits the tail into two with the edges being rounded.

Fishing: How to catch a South American Silver Porgy

For those who lose bait at the piers, some anglers say that the South American Silver Porgy is the culprit. For hook size, some people would use either a size 8-10 hook in order to catch them. They grow up to only 6-8 inches and only bigger if in deeper waters. They’re also quite fast and have a tendency to just nibble on the bait before finally eating the whole thing. When going fishing, ask first yourself what size you’re going for. The South American Silver Porgy can grow up to 15 inches and if you’re going that big, you’ll have to use clams or sandworms as bait. Otherwise, squid will be much easier. A lot of anglers have mentioned that squid stays on hooks better.

Once you’ve figured that out, head towards the area. Unlike some of their Porgy cousins, the South American Silver Porgy don’t stay in their reefs. They stay on the shallower ends of the water. It takes a bit of sight-fishing but once you find them, make sure you have your bait and line ready. Make sure you have a braided line that will withstand the current. Make sure to also add some chum made from crushed clams and shrimp to attract them to your fishing spot.

 

Habitat and Distribution

 South American Silver Porgy have a preference for clean water near rocky coasts and coral areas. They don’t wander too far into deep, staying in waters that are around 50 feet in depth. However, the South American Silver Porgy appear to have a preference for turbulent waters, probably as a way to help them keep moving. They can also be found in sandy shores and seagrass beds. They usually appear in schools as well.
