SIU grad’s research illuminates pollution threats to endangered Calif. fish

The Sacramento Deep Water Ship Channel was still and quiet as the boat cut through the morning fog. For Cristina La, then a graduate student at Southern Illinois University Carbondale, this was the moment she had been preparing for over months of planning and lab work. Somewhere below the boat swam the last remaining stronghold of California’s delta smelt — a tiny, silvery fish whose decline has become a warning signal for the entire Sacramento-San Joaquin Delta ecosystem.

SIU Carbondale's Class of 2029

SIU Carbondale enrollment up in Southern Illinois region, overall enrollment remains steady

Southern Illinois University Carbondale is pleased to report that the overall enrollment on the 10th day of class for fall 2025 remains steady (flat) at 11,785 – only five fewer students than last year – which saw a record percentage enrollment growth. This figure reflects increases among several demographics, including new students from the Southern Illinois region (6%), new students from states bordering Illinois (16%) and online students (23% growth overall, 161% in graduate programs). The success of the university’s enrollment stability was also greatly enhanced by the strategic efforts of Academic Affairs, yielding a 5% growth in retaining continuing students – from 7,532 to 7,898. Despite these increases, an area of concern was the overall reduction of international students, which accounted for the largest decrease among various groups.
