Invertebrate animals : collection and preservation /

Abstract

Preserving Living animals should be placed first in 50 per cent alcohol and then in 70-90 per cent alcohol. Alternatively, they may be placed directly in 3-5 percent neutral formalin solution. If material is being collected for subsequent cytological examination specialist literature on fixation techniques should be consulted. References

Methodological bias in the estimations of important meroplanktonic components from near-shore bottoms

“…Still, we demonstrated that methodological constraints, such as the use of formalin for preservation, can hinder abundance estimations and species identification of important meroplanktonic components, such as sponge and lecithotrophic bryozoan larvae, even though samples are collected very close to parental habitats. The implications of the use of formalin for the identification of adults and early stages of various marine animals have been reported in the literature (see Lincoln & Sheals 1979, Nishikawa & Terazaki 1996, Geldmacher & Wieland 1999 and it is also commonly accepted (although no explicit publications exist) that formalin has detrimental effects on various invertebrate larvae. However, and in spite of such knowledge, this remains a commonly-employed method for preserving invertebrate larvae and plankton in general.…”
