By contrast, Paraleptophlebia spp. (mayfly, Epherneroptera) are relatively...

Creator:: Moosapanah, G. Reza
Abstract:: This investigation demonstrates the feasibility of a polyculture system using effluent water from land-based salmon culture systems to feed juvenile Manila clams, Tapes japonica (Deshyes), and an evaluation of an artificial diet for feeding juvenile clams. An economic analysis of the polyculture system was compared to cultures of a single...
