Length-Weight relationships

Let's suppose we have the following a list of species stored at species.txt:

cat species.txt

Odontesthes regia
Engraulis ringens
Menticirrhus undulatus
Sciaena deliciosa

We can obtain their LWRs by using:

fishbase.py species.txt -lw

While output file name is based on input and on above example this file is named species_fishbase_lw.tsv, option -out can also modify default names.

cat species_fishbase_lw.tsv

species	a	b	n	Country	RangeLength
Odontesthes regia	NA	NA	NA	NA	NA
Engraulis ringens	0.02150	2.604	NA	Peru	NA
Engraulis ringens	0.00674	3.000	NA	Peru	NA
Engraulis ringens	0.00460	3.121	NA	Chile	NA
Engraulis ringens	0.00421	3.144	NA	Chile	NA
Engraulis ringens	0.00375	3.221	NA	Chile	NA
Menticirrhus undulatus	0.01027	3.000	1	NA	61.0, 61.0
Sciaena deliciosa	NA	NA	NA	NA	NA

Synonyms

We can also extract species synonyms according to this database with the option -syn:

fishbase.py species.txt -syn

Again, by default fishbase.py uses its input to name its output, however this can be modified with -out option.

cat species_fishbase_syn.tsv
