Title: | A Small Collection of Fish Population Datasets |
Version: | 1.0.1 |
Maintainer: | Conor Neilson <condwanaland@gmail.com> |
Description: | A collection of four datasets based around the population dynamics of migratory fish. Datasets contain both basic size information on a per fish basis, as well as otolith data that contains a per day record of fish growth history. All data in this package was collected by the author, from 2015-2016, in the Wellington region of New Zealand. |

Growth data of adult fish
Description
A dataset containing daily age and growth data for adult Galaxis maculatus.
Usage
adult_growth
Format
A dataset containing 16795 rows and 4 variables
- fish_code
Foreign key, matches to 'adults'. Identifies the fish being measured.
- period
a count of each otolith increment. Counts a day in the fishes life
- position
the distance of the increment from the centre of the otolith
- distance
the distance of the increment from the previous increment
Examples
data(adult_growth)
Adult fish metrics data
Description
A dataset containing metrics data for adult Galaxis maculatus.
Usage
adult_metrics
Format
A dataset containing 48 rows and 6 variables
- fish_id
a unique identifier for each fish
- standard_length
standard length of the fish (distance from posterior to caudal peduncle), cm
- body_depth
body depth of the fish at its maximum point, cm
- age
Age of fish when caught (days)
- birthdate
Day fish hatched
- growth_rate
Average daily growth of fish (mm/day)
Examples
data(adult_metrics)
Base table of adult fish sample sites and dates.
Description
A dataset containing base location and time catch information for adult Galaxis maculatus.
Usage
adults
Format
A dataset containing 48 rows and 4 variables
- fish_code
Primary key, uniquely identifies a fish
- site
Site where fish was caught
- day
Day group fish was caught on (H1 = 1st day fishing, H3 = 3rd day fishing). Used for by-day grouping analysis. For actual catch date see 'catch_date'
- catch_date
Date that the fish was caught on
Examples
data(adults)
Growth data of juvenile fish
Description
A dataset containing daily growth data for juvenile Galaxis maculatus.
Usage
juvenile_growth
Format

Foreign key, links with 'juveniles'
- otolith_code
Alternate key
- period
a count of each otolith increment. Counts a day in the fishes life
- position
the distance of the increment from the centre of the otolith
