From clothing giants and Leonardo di Caprio to new trade threats and shrimp market shifts, April was a fun-packed month for seafood news.

US clothing firm Patagonia's critical video on salmon hatcheries and salmon farming, revelations Leonardo di Caprio had spoken out against Alaska's controversial Pebble Mine development, and news that salmon prices suffered a "bloodbath" during the month, hit IntraFish's most-read headlines in April.

Also up there in the top most read, Senior Reporter Lola Navarro wrote how Ecuador's shrimp producers are feeling conflicting effects from the closure of back-door trading into China and asked if shrimp prices had reached rock bottom.

Editor-in-Chief Drew Cherry offered insight into Canadian seafood giant High Liner's turnaround plans when he sat down with CEO Rod Hepponstall one year into his new role.

Sticking in North America, it was bad news for Norwegian salmon producers who began to feel the pressure from not one, but three lawsuits against them for alleged price fixing in the US market. Whether it will go down the same track as the canned tuna industry lawsuits remains to be seen, but the effects of that are still playing out years later, so it's definitely one we'll be keeping a close eye on.

Reporter Rachel Sapin also wrote an interesting piece on Maine's growing aquaculture industry and whether it stands a chance in the face of increasing opposition.

In New Zealand, aquaculture is facing similar challenges, although climate change is also a key decider in the increasing need for the sector to move offshore, as New Zealand King Salmon CEO Grant Rosewarne told Editor Rachel Mutter.

We also heard how a new partnership with e-commerce giant Alibaba is part of Thai Union's strategy to take on the Chinese market.

Trade battles still bubbled away during the month with the EU hitting back against threatened US trade sanctions with a long, seafood-inclusive list of tariff target threats, pollock, salmon and lobster included.

But that is just a taste of the news, analysis and insight we featured on IntraFish last month.
