Welcome to rfishbase 5! This is the fourth rewrite of the original
rfishbase package described in Boettiger et
al. (2012).
Another streamlined re-design following new abilities for data hosting and access. This release relies on a HuggingFace datasets hosting for data and metadata hosting in parquet and schema.org.
Data access is simplified to use the simple HuggingFace datasets API instead of the previous contentid-based resolution. This allows metadata to be defined with directly alongside the data platform independent of the R package.
A simplified access protocol relies on duckdbfs for direct reads of
tables. Several functions previously used only to manage connections are
now deprecated or removed, along with a significant number of
dependencies.
Core use still centers around the same package API using the fb_tbl()
function, with legacy helper functions for common tables like
species() are still accessible and can still optionally filter by
species name where appropriate. As before, loading the full tables and
sub-setting manually is still recommended.
Historic helper functions like load_taxa() (combining the taxonomic
classification from Species, Genus, Family and Order tables),
validate_names(), and common_to_sci() and sci_to_common() should
be in working order, all using table-based outputs.
rfishbase 1.0relied on parsing of XML pages served directly from Fishbase.org.rfishbase 2.0relied on calls to a ruby-based API,fishbaseapi, that provided access to SQL snapshots of about 20 of the more popular tables in FishBase or SeaLifeBase.rfishbase 3.0side-stepped the API by making queries which directly downloaded compressed csv tables from a static web host. This substantially improved performance a reliability, particularly for large queries. The release largely remained backwards compatible with 2.0, and added more tables.rfishbase 4.0extends the static model and interface. Static tables are distributed in parquet and accessed through a provenance-based identifier. While old functions are retained, a new interface is introduced to provide easy access to all fishbase tables.

Installation
remotes::install_github("ropensci/rfishbase")

library("dplyr") # convenient but not required
Getting started
Generic table interface
All fishbase tables can be accessed by name using the fb_tbl()
function:
fb_tbl("ecosystem")

You can see all the tables using fb_tables() to see a list of all the
table names (specify sealifebase if desired). Careful, there are a lot
of them! The fishbase databases have grown a lot in the decades, and
were not intended to be used directly by most end-users, so you may have
considerable work to determine what’s what. Keep in mind that many
variables can be estimated in different ways (e.g. trophic level), and
thus may report different values in different tables. Also note that
species is name (or SpecCode) is not always the primary key for a table
– many tables are specific to stocks or even individual samples, and
some tables are reference lists that are not species focused at all, but
meant to be joined to other tables (faoareas, etc). Compare tables
against what you see on fishbase.org, or ask on our issues forum for
advice!
fish <- c("Oreochromis niloticus", "Salmo trutta")
fb_tbl("species") %>%
mutate(sci_name = paste(Genus, Species)) %>%
filter(sci_name %in% fish) %>%
select(sci_name, FBname, Length)
# A tibble: 2 × 3

In most tables, species are identified by SpecCode (as per best
practices) rather than scientific names. Multiple tables can be joined
on the SpecCode to more fully describe a species.
To filter species by taxonomic names, use the taxa table from
load_taxa(), which provides a joined table of taxonomy from subspecies
up through Class, along with the corresponding FishBase taxon ids codes.
Here is an example workflow joining two of the spawing tables and
filtering to the grouper family, Epinephelidae:
library(rfishbase)
library(dplyr)
## Get the whole spawning and spawn agg table, joined together:
spawn <- left_join(fb_tbl("spawning"),
fb_tbl("spawnagg"),
relationship = "many-to-many")
# Filter taxa down to the desired species
groupers <- load_taxa() |> filter(Family == "Epinephelidae")
## A "filtering join" (inner join)
spawn |> inner_join(groupers)
# A tibble: 227 × 95

Species Names
Always keep in mind that taxonomy is a dynamic concept. Species can be split or lumped based on new evidence, and naming authorities can disagree over which name is an ‘accepted name’ or ‘synonym’ for any given species. When providing your own list of species names, consider first checking that those names are “valid” in the current taxonomy established by FishBase:
validate_names("Abramites ternetzi")
[1] "Abramites hypselonotus"
rfishbase can also provide tables of synonyms(), a table of
common_names() in multiple languages, and convert common_to_sci() or
sci_to_common()
common_to_sci(c("Bicolor cleaner wrasse", "humphead parrotfish"), Language="English")
# A tibble: 5 × 4
Species ComName Language SpecCode
<chr> <chr> <chr> <int>
1 Labroides bicolor Bicolor cleaner wrasse English 5650
2 Chlorurus cyanescens Blue humphead parrotfish English 7909
3 Bolbometopon muricatum Green humphead parrotfish English 5537
4 Bolbometopon muricatum Humphead parrotfish English 5537
5 Chlorurus oedema Uniform humphead parrotfish English 8394
Note that the results are returned as a table, potentially indicating other common names for the same species, as well as potentially different species that match the provided common name! Please always be careful with names, and use unique SpecCodes to refer to unique species.
SeaLifeBase
SeaLifeBase.org is maintained by the same organization and largely
parallels the database structure of Fishbase. As such, almost all
rfishbase functions can instead be instructed to address the
fb_tbl("species", "sealifebase")

Versions and importing all tables
By default, tables are downloaded the first time they are used.
rfishbase defaults to download the latest available snapshot; be aware
that the most recent snapshot may be months behind the latest data on
fishbase.org. Check available releases:
