TAISHAN — To Lu Zice, discarded oyster shells are treasures. Taishan, a county-level city administered by Jiangmen in Guangdong province, generates over 100,000 metric tons of waste oyster shells annually, threatening the environment.

To solve this, Guangdong Bevan Biology Co, founded by Lu, processes 50,000 to 60,000 tons of shells annually, yielding products worth over 20 million yuan ($2.9 million). Over the next three years, Lu plans to scale production to 100,000 tons, valued at over 100 million yuan. The company plans to expand further to process 150,000 to 200,000 tons annually, effectively eliminating Jiangmen's oyster waste.

Collaborating with the Guangdong Academy of Agricultural Sciences, Lu recently partnered with Zhu Ronghua, Chairman of Qi Yong Tang Health Technology (Guangdong) Co. In March, they joined forces to convert aquaculture waste into high-value items like soil conditioners and ecological powder coatings. Historically used in building materials since the Tang and Ming dynasties, oyster shell products now drive a sustainable, full-scale industrial chain along the South China coast.

Japan’s bluefin tuna hauls are surging nationwide, forcing officials to impose strict restrictions or suspend fishing entirely as some prefectures race toward their annual limits at an unprecedented pace.

According to the Fisheries Agency, the April catch of large bluefin tuna weighing 30 kilograms or more reached a staggering 320.7 tons. This figure marks a historic record for the month since the current management system began in 2018, nearly doubling the volume recorded the previous year.

Smaller bluefin tuna weighing less than 30 kilograms also hit record highs for April, increasing by 10.4 percent to 300.6 tons.

Pacific bluefin tuna fishing is managed under strict international agreements, which subject Japan's waters to annual catch quotas starting each fiscal year in April.

The rapid surge has put immediate pressure on local limits. Fukui and Toyama prefectures have already exhausted more than 50 percent of their quotas for large bluefin tuna, while Kochi has surpassed the 40-percent mark. For smaller tuna, Fukushima Prefecture has already burned through over 90 percent of its allocation, and Fukui is past 50 percent.

Lahad Datu Maritime Zone Director, Maritime Commander Dzulfikhar Ali, stated that the vessels were intercepted between 3:30pm and 5:00pm during Op Sejahtera 1/2022 and Op Tiris 4.0.

The first vessel was caught fishing for anchovies 0.37 nautical miles southeast of Kampung Jaya Baru, breaching regulations by operating less than 1.5 nautical miles from the shoreline. A 25-year-old local skipper and two foreign crew members, aged 43 and 57, were detained. The vessel and its catch are valued at RM115,000.

In a second operation 0.23 nautical miles east of Kampung Jaya Baru, a suspicious pump boat was intercepted. The skipper jumped overboard and escaped to land. Authorities discovered fish caught using explosives, seizing the boat and catch valued at RM7,000.

All seized items and suspects were taken to the Lahad Datu Fisheries Jetty for further investigation.

The Norwegian-owned salmon farming company said it may have to seek further funding, however, and it is currently exploring possibilities.

During the period, Proximar harvested the last mixed batch of fish affected by earlier production disruptions.

Biological performance remained strong, with superior share above 95% and high survival rates of 97.6% in the grow-out.

The company doubled its turnover from Q1 2025 to NOK 60.1 million (£4.8m) which included an insurance payout.
