Effects of skipped spawning on the reproductive potential of argentine hake (Merluccius hubbsi)

We analyzed the effect of skipped spawning on the estimates of length and age at maturity and on the reproductive potential of Argentine hake (Merluccius hubbsi) from the Patagonian stock during the spawning peaks between 2005 and 2013. The length at first maturity increased by 2–3 cm in total lengt...

The reduction in egg production caused by skipped spawning ranged between 3.56% and 12.12%, when we used the maturity models with age data, or between 2.70% and 6.80%, when we used the models with TL data.
