This is the number of young fish that survive (from birth) to a specific age or grow to a specific size. The specific age or size at which recruitment is measured may correspond to when the young fish become vulnerable to capture in a fishery or when the number of fish in a cohort can be reliably estimated by a stock assessment.
Fish from a given stock that become available (i.e., recruit) to a fishery.
Additions to a population, either through birth or immigration, or, in the case of net recruitment, the differences between such additions and the losses resulting from death or emigration.
The addition of individuals to a population through reproduction and immigration.
the influx of new organism members into a population due to reproduction or immigration
The number of fish (recruits) added to the exploitable stock, in the fishing area, each year, through a process of growth (i.e. the fish grows to a size where it becomes catchable) or migration (i.e. the fish moves into the fishing area).
the process by which juvenile fish enter the exploitable stock and become susceptible to fishing.
number (or biomass) of fish which comes to a given --year-class or length-class during a specified period of time.
Entry of individuals into a particular population, life stage, age, or size category; e.g., recruitment into the stone crab fishery occurs when crabs reach legal size
The residue of those larvae that have: (1) dispersed; (2) settled at the adult site; (3) made some final movements toward the adult habitat; (4) metamorphosed successfully, and (5) survived to be detected by the observer.
This term has several meanings in fishery science. One definition is the size at which a fish can be legally caught. Another is the size at which a fish becomes susceptible to a particular fishing gear. In the context of this website, it refers to the number of young-of-year fish which enter the population in a given year.
Recruitment is a broad term that includes settlement of young-of-the-year abalone (less than 31 mm), growth into reproductive sizes that contribute to spawning populations (greater than 50 mm), and entry into the fishery at sport legal size.
A measure of the number of fish that enter a class during some time period, such as the spawning class or fishing-size class.
the young plants and animals that have survived the settlement phase on rocks/substrate that we can count in the field.
Successful natural reproduction and survival of juvenile fish to a size or age where many are likely to survive contribute to future generations.
(1) Entry of new fish into a population, whether by reproduction or immigration; (2) Addition of new individuals to the fished component of a stock (because they have acquired the size, age, or location that makes them part of it.)
The addition of new individuals to a population.
