Forecasting the number of individuals entering a fishery is critical for sustainable harvest and thereby management actions, but it remains challenging due to the considerable inter‐annual variability and the complex nature of causal factors. This long‐standing ‘recruitment problem’ has become even more urgent under ongoing climate change and the associated regime shifts overturning traditional predictive models. Leveraging th...

Marine capture fisheries play crucial roles in global aquatic protein supply and livelihoods of millions of people. Anthropogenic climate change comes as an overlying threat, potentially necessitating substantial adjustments of harvest control rules or rebuilding plans, especially for species (stocks) that are naturally adapted to restricted environmental fluctuations. Stock productivity, defined as surplus production provided...

The reproductive success of marine ectotherms is especially vulnerable in warming oceans due to alterations in adult physiology, as well as embryonic and larval survival prospects. These vital responses may, however, differ considerably across the species' geographical distribution. Here we investigated the life history, focusing on reproductive ecology, of three spatially distant populations (stocks) of Atlantic cod ( Gadus m...

The present study tracked oocyte development over 9 months and noted incidences of ‘skipping’, i.e. , adults terminating their upcoming reproductive cycle, in field‐caught north‐east Arctic (NEA) haddock ( Melanogrammus aeglefinus ), currently the largest stock of this species. Applications of advanced image and histological techniques revealed the presence of cortical alveoli oocytes (CAO), which prevailed as the most advance...

Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 fisheries resources—ranging from data‐poor to data‐rich stocks—in the North East Atlantic are most likely affected under the intermediate climate emission scenario RCP4.5 towards 2050. This region is one of the most productive waters in the world but subjected to pronounced cl...

Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild population dynamics, fisheries and aquaculture. In this extensive review spanning tropical and cold‐water environments, we examine the impact of higher‐than‐optimal temperatures on teleost reproductive developmen...
