linking tables for maximum efficiency

Hi,

I am trying to build two tables containing information about fish that we
have collected:

tbl Fish:
FishPK (one for each individual fish; autonumber)
CollectionPK (links to tbl Collection which contains information about where
and when we collected the fish)
FishName
FishAge
FishSex
FishLength

tbl FishAnalysis:
FishPK
Analysis1
Analysis2
Analysis3
Analysis4

The chemical analyses are only performed on a subset of the entire fish
collection.

I am pretty happy with this design, but am open to suggestions! In
particular, I want to know if this design allows me to:

1. build a query to find the individual fish that have (or have not) been
used for chemical analyses

2. build a form for entering results of the analyses - when I receive the
data, it looks like this
Collection ID (not PK)
FishName
Analysis1
Analysis2
Analysis3
Analysis4
- which means that I have to collect data from two separate tables before
adding the new results to tbl FishAnalysis. How do I build a form to simplify
this process? And is my design correct to enable my form?

I would appreciate any input!

Thanks,
