We have estimated the power spectra of density fluctuations produced by cosmic strings with neutrino hot dark matter (HDM). Normalizing at 8h^-1 Mpc [where h=H₀/(100 km/sec Mpc) and H₀ is the Hubble constant] we find that the spectrum has more power on small ({}10h^-2 Mpc) scales than HDM+ inflation, less than cold dark matter (CDM) + inflation, and significantly less than CDM + strings. With HDM, large wakes ({~}20h^-2 Mpc) give significant contribution to the power on the galaxy scale and may give rise to large sheets of galaxies.
