The otoliths (or\nsimilar measurements of age) provide direct observed\ncoordinates of age and length. The tagging data provide\ninformation about the observed length at release and length at\nrecapture at a later time, where the age at release is unknown\nand estimated as a vector of parameters. The growth models\nprovided by this package can be fitted to otoliths only,\ntagging data only, or a combination of the two. Growth\nvariability can be modelled as constant or increasing with\nlength.", "License": "GPL-3", "URL": "https://github.com/arni-magnusson/fishgrowth", "Encoding": "UTF-8", "RoxygenNote": "7.3.3",
