How we take from the wild should be regulated and controlled....


it is, to an extent, by the marine aquarium council I mentioned before. MAC certified chains (collectors, importers, exporters) regulate the number of fish that are taken from specific areas and they work with local governments to set up zones where fish are not allowed to be taken for food or the ornamental fish trade. the main thing we can do is buy from MAC certified sources.

And here we go, my first catch Very Happy Right on spot!

Here they are saying exactly what is happening in this trade, here in Europe but is similar elsewhere.

Quote:
The number of ornamental fishes kept in German aquariums is rising, but the supply of offspring is not sufficient to meet the needs of the fish enthusiasts. Therefore, millions of ornamental fishes from foreign countries are being imported to Germany. This provokes a number of new problems regarding the protection of species and the animals' welfare during transportation. For the assessment of the transport conditions, 1000 shipments of ornamental fishes were evaluated at the Rhein-Main-Airport, Frankfurt, Germany. Water samples were taken from 100 shipments and were examined for anaesthetics. The results were disturbing: 41% of the shipments have total transportation times between 31-42 h resulting in an oxygen deficit in the transport bags (5.2%) and dead ornamental fishes. Also, damage of the transportation containers, high fish densities as well as drastic size differences among the fishes in one transport bag were noticeable. In 99% of the cases, formal defects could be noted. The German association of pet stores has declared that fishes belonging to three special fresh water families should not be kept in an aquarium, but 1200 of such fishes were imported. The HPLC analysis of the water samples revealed an additive. The non-declared anaesthetic 2-phenoxyethanol was present in all samples taken from shipments from Singapore. The results emphasize that improvements are urgently necessary for the control of the air transport and trade of ornamental fishes.

This one is a bit better, have a good read Smile

The trade and hobby should be geared towards healthy fish, rather than high volume but low grade fish; and also towards sustainable harvest and captive breeding. This we believe, is good for the trade, hobbyists, and will also help the cause of habitat and species conservation in general.

This is also interesting;

3.1 Condition Upon Arrival

The coral reef fauna totalled 601 specimens packed individually in bags of assorted dimensions. Anemones were packed without water or oxygen according to standard.

The seams of the bags which had been made with a thin strip welding machine are less leak-proof than the broad wafered seams and in some instances leakages had resulted in the death of the fish. The seams had not been tapered (as in the better bags made in Europe) resulting in sharp corners in which some fishes were trapped. The thickness of the bags was good and the quality of polyethylene sheeting from which they were made was good, the sheets having an even thickness.

The water temperature within the bags was adequate and above 20

Current ornamental fish packaging systems are characterized by very high fish loading densities and high metabolic wastes in the transport water after shipment. They focus mainly on management of the quality of transport water. Recent studies using the guppy as a model fish showed that post-shipment mortality could be reduced through enhancement of the stress resistance of the fish, and hence emphases should also be placed on the preparation of the fish for transport and recovery of the fish after shipment. Farmers can contribute significantly by applying nutritional prophylaxis before harvesting. Exporters may use the salinity stress test to identify fish lots of good quality for transport, apply health prophylaxis to eradicate parasites and optimize other techniques such as starvation of the fish or addition of salt to the transport water to enhance the stress resistance of the fish. Importers may adopt proper acclimation procedure and allow fish to recover in low salinity water to reduce post-shipment mortality. As the main bulk of post-shipment mortality is stress-mediated and occurs during the 1-week recovery period, the industry should consider revising the basis of the current warranty system for their customers, from death on arrival to cumulative mortality at 7 days post shipment (or death after 7 days, DA7), in order to cut down fish losses after shipment.

Read the Guarantee & Claim at the bottom of this link please, so you understand how this trade functions;
http://idfdiscus.com.my/terms.php

As I already mentioned once, most shops will get refunds and no one BUT fish are suffering the consequences in this trade.
I mean they are already ready for 5% of Discus loss per shipment, that is the usual fact, but sometimes it exceeds the 5% , I know this.
