I've never met anyone who uses strict Classical or Ecclesastical Latin pronunciation for scientific names; almost everyone uses a mishmash of pronunciations from Classical Latin and their native language. Vowels seem to be the worst part; most Latin vowels are pronounced rather differently from the same vowels in English, due to a linguistic event called "The Great Vowel Shift" (I'm not making this up). Most folks are more consistent about using Classical values for consonants.
So, Latin final "-i" is pronounced as English "-ee", while final "-ii" is pronounced as English "-ee ee" with a slight stop between the two syllables. Likewise Latin "ae" is pronounced much like English long "i", so all those "-idae" animal family names should end in "ih die", not "ih dee". I'm not suggesting anyone start pronouncing names this way, as it will only earn you funny looks.
A few examples of family names with Classical/typical English pronunciations:
Centrarchidae- "Kent rar kih die"/"Sen chrar kuh dee"
Cichlidae- "Kih klih die"/"Sih kluh dee"
Cyprinidae- "Ku prih nih die"/"Sie prin uh dee"
Names derived from languages other than Latin or Greek should not follow Classical pronunciation. So, if you're talking about Oncorhynchus apache, you would pronounce the "ch" in Oncorhynchus as a "k", but not so the "ch" in apache.

between my slurred speech and the hippy that works at my fish store there is likely to be some miscomunication... if you know what i mean
