Red tide has once again made its way into Corpus Christi Bay this week, and on Wednesday it brought with it sightings of dead fish along the shore.

The Texas Parks & Wildlife Department conducted more water sampling Wednesday afternoon and said there does not appear to be any major change in the red tide bloom that is now lodged in the bay.

Scientists noticed an increase in red tide from test results Monday in areas around the bay, including Indian Point Pier, Swantner and Cole parks. They also discovered a small fish kill in the area of Ropes Park.

The algal bloom is still considered to be in low concentrations, but even a slight increase can cause respiratory problems for everyone. Those most at risk for problems are anyone with respiratory ailments.

Authorities said it will take a seasonal climate change before the bacteria will dissipate -- a change of 10-15 degrees over a period of several days.
