Fish Bombs

A couple of weeks ago , I felt two bombs go off underwater. I was diving off Olango island near Cebu in the Philippines. The second of these was so loud that it spooked the shoal of fish I was watching, and made my adrenaline run hard for a few moments. Yet on the surface, there was no evidence of nearby bombing at all - indeed we were in a marine protected area with several dive and snorkelling vessels and a community patrol boat with no story to tell; the bombing must have been miles away, yet its underwater effect reached out way beyond its immediate impact.

Here in Sabah, something similar seems to be happening. Whilst I have never heard fish bombs in TARP, I have been told by others that they sometimes hear them - not exploding in the Park itself but several miles away up or down the coast. It is illegal in Sabah. But three days ago, newspapers report that a man killed himself and his estranged wife with one here in KK. And now it seems the Police will step up their efforts to enforce the law against fish bombing. They say they have caught five fish-bombers already this year; here's hoping this sad tale will truly mark the end of a not only hugely destructive and unsustainable livelihood practice, but a humanly dangerous one. An instructor friend of mine in the Philippines was near a bomb when it was detonated underwater and nearly killed, but challenging the boatmen involved was physically risky and he says the police are themselves afraid of the violence of fish bombers in the Philippines. Let's hope it is different here when (if) the police step up their campaign.

Here's a regular friend at Hanging Garden off Gaya island, photographed on 28th December 2006 ,who's cousins elsewhere in the state might benefit: the giant reef dwelling Broadclub cuttlefish Sepia latimanus (Mollusc Family SEPIIDAE).

304 fish species in TARP

31st May 2008 was gorgeous - blue skies and calm waves; this sea hare Aplysia dactylomela (a kind of giant sea slug from the family APLYSIIDAE) also seemed to think so as it charged across the sand off Sapi island to this clump of algae before grinding it to bits.

I gorged on my snorkelling session too: a better photo to upload with an improved description for one of my fish ID panels (Thalassoma lunare), a youthful colour variant to add for another (Lutjanus fulviflamma), an un-logged juvenile for a previously adult-only species (Halichoeres argus) and an adult photo for a species previously represented only by a juvenile (Pomacentrus chrysurus). Incidentally this caused me to concede that I had mistakenly recorded another such adult previously as Pomacentrus armillatus (which I have now removed from my checklist). Amazingly, this single snorkel session added 6 new species too, which (counting the discarded species) brings my total of observed species in the park to 304. Species added were Cephalopholis microprion (which stimulated a slight modification to my description of Cephalopholis cyanostigma), Cheilio inermis, Chromis viridis, Ctenochaetus striatus, Neoglyphidodon oxyodon and Pteragogus guttatus.
