Half of Murres seabird population dies after this happened
How To Protect The Ocean
In this episode of the How to Protect the Ocean podcast, host Andrew Luan discusses the significant decline in the population of common murres, a seabird species in Alaska, which has seen about half of its population die off—approximately 4 million individuals—since the marine heat wave known as "the blob" occurred from 2014 to 2016. The primary reason for this drastic decline is linked to the effects of the heat wave on the marine food web rather than direct thermal stress on the birds themselves. The heat wave caused shifts in the availability of food sources, leading to starvation among...

The Pacific bluefin tuna population has seen a significant increase in the number of female tuna capable of reproductive success, indicating a successful conservation effort. The recent stock assessment revealed a substantial rise in the population of female Pacific bluefin tuna able to reproduce, showing that international efforts to protect and manage the species have been effective in reversing the decline and promoting population growth.
This success story highlights the severe threats faced by the Pacific bluefin tuna population due to overfishing, with the stock plummeting by over 96% from its historic high. Despite these challenges, there has been a notable turnaround in the population status, particularly in increasing the number of reproductive females, a crucial milestone in the conservation of this species.
The conservation success of the Pacific bluefin tuna demonstrates that with dedicated efforts and effective management strategies, it is possible to reverse the decline of marine species and promote their recovery. The increase in the number of reproductive females is a positive sign for the future sustainability of the Pacific bluefin tuna population.
The significant rise in the number of female Pacific bluefin tuna capable of reproductive success showcases the effectiveness of conservation efforts and emphasizes the importance of continued collaboration and conservation measures to ensure the long-term survival of this iconic species.
The overfishing of Pacific bluefin tuna had devastating consequences, leading to a staggering 96% drop in population from its historic high. This drastic decline highlighted the urgent need for immediate and effective conservation measures to prevent the species from facing extinction. The episode discusses how a scientific report in 2012 revealed the alarming state of the Pacific bluefin tuna population, emphasizing the severe impact of overfishing on the species.
The significant decrease in the Pacific bluefin tuna population served as a wake-up call, indicating that urgent action was required to reverse the trend of depletion. The episode mentions how the exploitation of these large and valuable fish for commercial purposes, such as the celebratory auction where a Japanese sushi chain purchased a bluefin tuna for $1.7 million, demonstrated how financial interests often outweighed conservation concerns.
The episode also touches upon the slow growth and long lifespan of tuna species, making their recovery a lengthy and challenging process. The conservation success story of the Pacific bluefin tuna serves as a beacon of hope, showcasing that with coordinated international efforts and effective management strategies, it is possible to reverse the decline of overexploited marine species. This success story underscores the importance of implementing sustainable fishing practices and conservation measures to protect vulnerable marine species like the Pacific bluefin tuna.
The episode highlights the exploitation of endangered tuna species by corporations for profit, noting how the value of individual tuna species can increase as they become more endangered. This phenomenon occurs because the scarcity of a species drives up its market value, making each individual catch more lucrative for those involved in the fishing industry.
In the case of the Pacific bluefin tuna, despite facing a significant decline in population due to overfishing, there were instances where a Japanese sushi chain purchased a bluefin tuna for a staggering $1.7 million in a celebratory auction. This exorbitant price tag demonstrates how the demand for these endangered species can lead to inflated prices, creating a financial incentive for exploitation.
Furthermore, the episode mentions a common practice where corporations catch endangered tuna species, freeze them for extended periods, and then sell them at a higher price when the species is on the brink of extinction. This strategy essentially turns the exploitation of endangered species into an investment opportunity for these corporations, prioritizing short-term profits over the long-term sustainability of marine ecosystems.
The documentary "End of the Line," referenced in the episode, provides further insight into the exploitation of tuna species for profit. It delves into the practices of the tuna industry in various regions, shedding light on the detrimental impact of overfishing and the commodification of endangered species.
Overall, the episode underscores the alarming trend where the increasing rarity of certain tuna species can paradoxically drive their commercial value up, leading to their exploitation by corporations solely for financial gain. This highlights the urgent need for robust conservation measures and sustainable fishing practices to protect these vulnerable marine species from further exploitation and potential extinction.
