POV: You look over the stern and a 6-ton apex predator is playing in your wake. 🤯🐋 Absolute chills seeing this massive orca keeping pace right under the boat!

An interesting Review - Bioecology, Conservation Status and Breeding Efforts of Wild 𝐵𝑒𝑡𝑡𝑎 Fish (Teleostei: Osphronemidae) in Kalimantan, Indonesia: making the strong case for coordinated research and conservation programs to preserve Kalimantan's unique 𝐵𝑒𝑡𝑡𝑎 fauna. Kalimantan, the Indonesian part of Borneo, is a major centre of diversity for wild 𝐵𝑒𝑡𝑡𝑎 species, harbouring 29 species grouped into eleven species complexes.

"To enhance conservation effectiveness, several priority actions are recommended. First, there is an urgent need for the establishment and effective management of protected peat swamp forests and blackwater ecosystems, which represent critical habitats for many stenotopic 𝐵𝑒𝑡𝑡𝑎 species. Second, the development of standardized, science-based captive breeding and genetic management protocols is essential to support ex situ conservation and prevent genetic erosion in captive populations. Third, improved regulation and monitoring of the ornamental fish trade are necessary to mitigate unsustainable harvesting pressures on wild populations."

"Most breeding efforts to date have been informal and led by hobbyist communities rather than academic institutions or conservation agencies. The online platform, YouTube, has been utilized to share wild Betta captive breeding activities such as 𝐵. 𝑎𝑙𝑏𝑖𝑚𝑎𝑟𝑔𝑖𝑛𝑎𝑡𝑎. These efforts have contributed to basic knowledge on courtship behaviour, parental care (mouthbrooding or bubble-nesting) and juvenile development, but lack standardized protocols and genetic monitoring. The absence of genetically managed broodstock poses risks of inbreeding and loss of genetic diversity, which is particularly concerning for species considered for future reintroduction.

To support conservation goals, there is a pressing need to develop science-based breeding protocols that include water chemistry replication, broodstock management and health monitoring. Establishing ex situ assurance colonies for the most threatened species can also serve as genetic reservoirs in the face of habitat collapse.

Furthermore, collaborations between academic institutions, public aquaria, local NGOs and regulated hobbyist networks should be encouraged to share knowledge and resources. Successful models from other taxa, such as killifish and cichlids, demonstrate that community-driven breeding programs, when guided by scientific frameworks, can significantly aid conservation outcomes. A recent example comes from Indonesia, where the NGO Sulawesi Keepers has implemented coordinated captive-breeding and species-rescue initiatives for endemic freshwater fishes, illustrating how nongovernmental efforts can support conservation goals. While Kalimantan's wild 𝐵𝑒𝑡𝑡𝑎 species show promising potential for captive management, significant investments in research, training and policy frameworks are required to realize their role in long-term species conservation."

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁
Kalimantan, the Indonesian part of Borneo, is a major centre of diversity for wild 𝐵𝑒𝑡𝑡𝑎 species (family Osphronemidae), harbouring 29 species grouped into 11 species complexes.

These fishes occupy specialized habitats such as blackwater streams, peat swamp forests and acidic lowland rivers. Despite their ecological significance and popularity in the ornamental fish trade, many species are threatened by rapid habitat loss, overharvesting associated with the aquarium trade and pollution.

This review synthesizes current knowledge on the diversity, distribution, habitat preferences, conservation status and breeding efforts of wild native 𝐵𝑒𝑡𝑡𝑎 species in Kalimantan. Species-rich provinces such as West Kalimantan and Central Kalimantan support many localized endemics highly sensitive to environmental change. Peat swamp degradation and conversion to monoculture plantations are major threats to many habitat-specialist 𝐵𝑒𝑡𝑡𝑎 species, several of which are classified as endangered or critically endangered.

Captive breeding efforts remain limited and are largely conducted by hobbyists, with few science-based protocols in place. To ensure long-term conservation, integrated efforts involving habitat protection, sustainable harvest management and ex situ conservation through captive breeding are essential.

This review highlights the urgent need for coordinated research and conservation programs to preserve Kalimantan's unique 𝐵𝑒𝑡𝑡𝑎 fauna.

Dark sistem game @EASFCMOBILE @EASPORTSFC kaku.. dapet lawan sinyal oren kadang merah, padahal main mah aman itu sinyal gw stabil, kadang 15ms paling tinggi ya 30ms, yg kena imbas menyambung ulang malah gw taek. Device yg gw pake mh oke lah. Mmng taek nih kga pernah di fix apa ya

Volcanic lightning is always impressive to see, but it's not just an awesome photographic subject. It could also yield clues about the Earth’s geological past. This picture was taken by Takehito Miyatake during an eruption of sakurajima volcano in 2014 https://t.co/nxcqXE7s3N

Went walking around Gaines street yesterday in Tallahassee and had to snap a few photos of one of my old favorites from when I was at FSU. Pour one out for The Warehouse, no longer in business but one of the few remaining hints at what the area was like before College Town.
