Over 15 years of ocean science and conservation online
The world of fisheries management is so full of laws and regulations that it’s no wonder many fishermen feel persecuted by the government. That’s why I was pleasantly surprised to see the National Marine Fisheries Service trying something new.

Oceanic whitetip sharks are considered by many to be a poster-child for shark conservation. Once one of the most abundant species of pelagic sharks on Earth, unregulated overfishing throughout their global range had led to a precipitous decline in their population. In some parts of their range, the species has declined in population by more than 70% in the last few decades. Scientists haven’t been able to find them in significant numbers for many years. One of the few remaining known aggregation sites is Cat Island in the Bahamas, and that’s where an international team of researchers just went to find these animals.

Oceana has released their list of finalists for the Ocean Hero award. As always, the finalists represent people who have done some amazing things for our oceans. This year, one of the nominees for the “Junior Hero” category is Sophi Bromenshenkel, an 8 year old shark conservationist.
We are in the midst of a global extinction crisis. Biodiversity is in decline as species after species disappear. Some estimates predict that up to 50% of species will be committed to extinction by 2050. Other estimates claim the current rate of extinction may be 10,000 times the background rate. Many ecologists and conservationists have declared the current species decline the sixth great mass extinction.
A recent paper published in the journal Nature argues that our current estimates of species loss are based on a flawed model and tend to overestimate the magnitude of species decline. The paper has received plenty of attention, and has been heavily criticized by ecologists and conservation biologists. The paper is wrong, but it is wrong for the right reasons, and the criticisms it has garnered point to a gaping hole in our understanding of population dynamics.
In this week’s edition of Shark Science Monday, Claudia Li of Shark Truth discusses the Happy Hearts Love Sharks wedding contest, which aims to reduce the consumption of shark fin soup at wedding banquets.

The SeaMonster has posted a lengthy e-mail discussion among several key players in fisheries science regarding Ray Hilborn’s recent “Let us eat fish” Op-Ed in the New York Times. The discussion is, quite frankly, epic, and I encourage anyone interested in fish, ecology, fisheries, or seafood to give it a read. Forum on fish, food, … Read More “Forum on fish, food, and people at the SeaMonster” »
This week at the International Marine Conservation Congress, a great resource was introduced. Science to Action, an affiliate of Conservation International, released a dual volume called “A scientist’s guide to influencing decision making /a decision maker’s guide to using science”.

This morning, Plymouth Marine Laboratory launched a new public service announcement about ocean acidification entitled “Connecting science, industry, policy and public”. According to the Official MPA Blog:
Depending on your view of phylogenetics, a recent publication in Nature reporting the discovery of a new kingdom-level branch on the tree of life, basal to Kingdom Fungi, is either a major revision of our current view of taxonomy or completely unsurprising and expected. While we mostly refer to the four kingdoms within Domain Eukarya as Protista, Plantae, Fungi, and Animalia, it’s understood by the scientific community that Protista is essentially a catch-all category, not a true clade, for eukaryotes that don’t quite fit into the other three groups. While this is convenient for organization, it fails to adequately express the diversity of protists. Four kingdoms is a useful system, but there’s no reason why diversity at the kingdom level couldn’t be much higher. A strict cladist could create hundreds, if not thousands of kingdoms from Protista alone.
