While we may have lagged recently on our blog posts (our apologies) the Society has nevertheless been very busy at Wreck Pond. In mid-June, we started our river herring young-of-year (YOY) monitoring. As its name implies, this monitoring targets river herring born earlier in the year, and is complementary to our spring fyke net sampling: whereas the spring fyke sampling lets us know when and how many adult river herring are coming into Wreck Pond to spawn, the YOY monitoring lets us know if the spawning has been successful. The results of previous years’ work indicate that at least some YOY river herring migrate downstream in Wreck Pond in early summer. Because of this, the Society has expanded the timeframe of YOY monitoring to start in early June instead of September as was done the first two years of the survey.
On July 12, 2018, the Society caught 142 YOY alewife. This is a fantastic catch considering the most we have ever caught for an entire season was five. Further, the following week we caught nine more. In addition to alewife, we have caught a number of other species including Atlantic silverside, stripped killifish, mummichog, northern puffer, and one short bigeye.
