| Remarks | Abstract: A study of the macrobenthos of the tidal Delaware River between Burlington and Trenton, New Jersey, included measurements of density and biomass for common species. Tubificidae (Limnodrilus) were dominant, comprising over 90% of all organisms taken in the 3-year study period. Density seemed to be a function of water temperature (20-25 C, optimal) and was greatest in late spring and early summer. Other common species were larval Procladius culiciformis (Chironomidae) and Corbicula manilensis (asiatic clam). Procladius was most abundant in late summer just prior to and during emergence. The asiatic clam was in the process of colonizing the area and growth data have been calculated. Potential relationships between numbers and standing crop of the common organisms with sediment type, and seasonal changes were explored. |
