SANIBEL ISLAND, Fla. -- Friday marks two years since the nation's worst offshore oil spill.  BP's underwater well sparked an explosion on the Deepwater Horizon rig on April 20, 2010.  An estimated 206 million gallons of crude oil flowed into the Gulf but yet some are still seeing the effects two years later.

Some fisherman who fish in Gulf waters are seeing some mysterious looking fish.  Good news is, those fish aren't in southwest Florida but that could change in time.

It's been two years since the Deepwater Horizon drilling rig exploded, sending oil gushing into the Gulf for nearly three months before it was stopped.  Scientists Bruce Neill with Sanibel Sea School says, even though oil didn't reach southwest Florida shores, that could change.

"Perhaps we didn't have the oil, but the fish that were reproducing in areas that are more heavily contaminated by oil and dispersant will now move in their larval stages throughout the Gulf of Mexico," said Neill.

Reports show in the northern Gulf of Mexico, fish have lesions, open sores, chewed up fins.  Something Neill says is most likely from the 2010 oil spill.

"Since the Gulf oil spill, the rate of fish lesions has increased between 200 and 500 times.  The number of fish and crab and other marine life with deformities have been found," said Neill.

Fisherman Gendun Sakyal saying catching the big one isn't coming down to the oil spill.

"I didn't see any fact, I've seen little fish a lot in groups and thats a really good sign," said Sakyal.

While evidence from scientists isn't conclusive, the oil spill in April 2010 is still being felt and with the way the circle of life works, it could have a lasting effect.

"It would be nice to think that biology was so localized but the reality is that the way that most marine organisms reproduce is that their larvae travels long distances.  I think that we will continue to see the effects for years to come,: said Neill.

Quite a few of the fisherman in southwest Florida WINK News spoke with, say they haven't seen much backlash of the oil spill.
