I took John's suggestion that I am misleading this "arm chair" forum personally ... it may have influenced the tone of my response
John,
I have been unable to confirm whether or not a resource assessment has been completed in Batasan, rapid appraisal or otherwise. Nor have I been able to confirm whether catch and effort is being monitored nor whether there is any information on the number of fishers exploiting the area nor even the size of the fishing ground. In addition to asking these questions on RDO, I posed these questions to MAC directly and the silence has been … well deafening. Almost three weeks now, and I am still waiting for a simple “yes/no” response. If it has been done, how hard would it be to simply say “yes, we’ve done it on this date”
Since it is your understanding that a rapid assessment has been done, could you please confirm when and that it was indeed using MAQTRAC? Thank you.
Frankly, I don’t trust statements such as: “the fish collected in quantity are most abundant”. Cow patties that butterflies, lionfishes and groupers (as you list) are most abundant on the reef. Naturally, these families are in low abundance. Groupers on the Great Barrier Reef, for instance, form less than 2% of the mobile community which doesn’t include all the damsels, gobies and blennies. Throw in the site attached species, and this proportion probably drops by half to two thirds. Butterflies are also not that common.
As to my statement that you can swim for 20 minutes on a typical reef in Bohol (I didn’t say Batasan in particular) and see few fish … I stand by this assessment for the Bohol reefs in general, with some notable exceptions, few and far between. I worked in Bohol for three years and our team quantitatively surveyed 30 reefs. I have personally probably swum on a 100 along that coast. Densities are outrageously low and arguing for additional pressure through collection … in the absence of resource assessments and catch data … is, well irresponsible and while certifiable …IMO, only for Bellevue.
Your suggestion that the reefs in this area are “adapted to coastal runoff” shows a poor understanding of the history of the area and reef ecology. The reefs of northern Bohol have been hammered by coastal runoff in the past 50 years associated with land clearing. Evolution certainly doesn’t occur that quickly and the reefs in Bohol are best described as heavily degraded rather than "adapted". They are not ok. I first dove in the Phils in 1981 … and the change since even then is remarkably depressing. For those new to the area, it may however be less obvious.
How do we know that the reefs from Batasan have “consistently produced a limited number of species" over the years"? I know there are no long term fisheries data for the area. Did MAC do formal interviews with fishers to assess historical catches and changes since? Is that information available? Our interviews with fishers in Bohol suggested declines in seahorses of 80% since the 60’s.
Great that MAC is collecting catch data (summarising invoices?) but what about effort ? Alone these data are as helpful as the GMAD report for assessing sustainability.
What about the in situ resource assessments? You say it is difficult. I disagree but say for a moment it is, why is MAC then pushing MAQTRAC ? Seems inconsistent? Say you’ll do it, get the tool developed, and then it’s too hard ? Say you’ll do it, certify and then a year later still be saying “it’s too hard?”. Ouch. How do you explain that to funders?
Resource assessments with good statistical design for most of the fish targeted for aquarium collection are, to borrow an Aussie expression, a piece of piss. Straight forward. Many are sufficiently site attached (fish not aussies). What is difficult is getting the capacity within the village to do the work … hiring a good Community Organiser … hiring a good biologist. You need to put the work into the VILLAGES not into Manila.
I am offended that you suggest I am misleading an ”arm chair” audience. I have more integrity than that. I also have more respect for this gang than that .. particularly my good friend Kalk. And ‘sides, it is not an armchair audience. There are quite a few members with their own direct experience underwater in the Phils plus those on the receiving end of fish and information from the field. I also have consistently backed up my statements with references, data or indicated the relevant professional experience.
However, your pollyanna anecdotes based on a quick fly through are a perfect example of such … influence. Went for a swim … lots of fish. Another example would be your inability to provide basic information on the Batasan MPA (e.g. size) whilst implying its mere presence is leading to sufficient spill over to balance collection …sounds great, eh?
Wa’ay problema dinhi.
I stand by my assessment of the resource based on a number of years experience in Bohol and even more years experience with the methods needed to do the work (despite being a youthful 60’s baby). How long were you there John ? How many reefs did you visit? I LIVED IN THE VILLAGES. I live and breath statistical design professionally.
Are you questioning my ability to see fish? I wear glasses but my mask is prescription. I have worked on reefs in the Caribbean,
Red Sea and SE Asia for more than 15 years. I am at least competent at counting fish, recognising that cryptics are always hard and short of rotenoning the reef (or hang on, cyaniding or dynamite) difficult to count. I haven’t seen the study of Peter’s but differences in density could simply reflect differences between areas. I don’t know where the roller beam trawl was … my guess would be in deeper water, off reef and these communities might have higher biomass; may also have caught more schooling fish, dunno. But out of context, it means nothing to me.
While I have your attention, perhaps you could tell me why MAC is/was pushing into Bilang-bilangan for a CAMP given there has been no historical aquarium collection there? Why add pressure? Looking for a better source of fish than the “healthy, consistently productive” reefs of Batasan?
Sincerely
Jessica
