To avoid similar establishments, we suggest regular malacologic and parasitologic surveillance of at least the thermal and hypothermal water bodies for these tropical invaders around European settlements.
During colder than average winters, ladyfish have experienced hypothermal mortality in both Tampa Bay (Springer and Woodburn, 1960) and the Indian River Lagoon (Snelson and Bradley, 1978).
These several relictual populations collectively suggest a wider distribution of the species to the north in the past, during a hypsithermal period, and a partial withdrawal during the current hypothermal period, occurring not long enough ago to have permitted subsequent taxonomic differentiation.
At the Ambassador mine and in the East Hills Area east of the mine, there are gold-quartz hypothermal veins, which were deposited under conditions of high temperature and pressure, probably genetically related to the later stages of emplacement of the preCambrian age quartz diorite mass.
He added "The mineralising system we are seeing at Nevera is very similar to prototype porphyry Cu and Cu/Au systems seen around the world with a large central intrusion surrounded by variably mineralized multiple porphyry apophyses, sitting at the base of a large mineralised hypothermal system with multiple mineral deposits, and this bodes well for future drilling".
The effect that this northward dispersal pattern has upon the population depends on whether these juveniles return south during autumn to overwinter or whether they become expatriated from the spawning population and die from hypothermal winter conditions at temperate latitudes.
