"Without offspring net " hit piscine shrimp seedling to play havoc with piscatorial resource
Just passed in April, the fisherman with coastal the East China Sea entered Fu Xiu period it seems that, anchor of on 1000 fisher is in fishing port, fishermans are depressive completely on the face, "The East China Sea does not have a fish " become the fisherman's most agonized feeling. A fisherman describes Zhejiang so: 10 hours, with the diameter 70 rice, circumference 1000 meters net, be in ceaselessly maritime sweep anything away 35 sea mile, the fish that scoops up is worth 89 yuan only.
"A few this years the net is buckled smaller and smaller, closer and closer, say to should not make this kind of net normally, but do not add secret network to buckle washed-up, want be out of pocket, do not hit a fish. " Shandong flourish becomes benefit of piscatorial Zhang Sheng to say, 45 years before, go to sea 4 days can hit one boat fish, want abrass faucet aerator bility 10 days to hit almost now full, and those who hit is basic it is small fish, can sell when feed only, the price 2 yuan of ／ jin.
Flue knits closer more, results is less and less however
Be in our country a few more coastal besmear of the coastal waters of province, beach, everywhere sees a few cascade fold the net that vertical stroke rises to provide, these nets or tall or low, or scanty or close, only same place is mesh close, as seawater refluent, no matter big Yu Xiaoyu is met,be blocked by the net.
The name that fishermans have to these nets special also figure: "Without offspring net " " ground basket net " " centipede net " " the net that confuse fetch " ... piscine shrimp once " join a network " , do not have the likelihood that flee for one's life basically.
Annual 4 to June, be shrimp lay eggs period, some fisher set filter of network of close look line to catch shrimp roe through be being added in the net. Network of close look line cries again " close eye net " , 1 millimeter does not reach mesh size, the mosquito-curtain mesh that uses than summer is small still, fisherman of this boat hill returns reason figure ground call it " hole of shrimp roe bag " .
Because excessive catch, resource of fishery of the East China Sea is close to hopeless situation. Big fish was caught catch small fish, piscatorial net knits closer more, results is less and less however. "Go out now true never mind is great fish, it is head of a few small fish. Piscatorial branch just puts down fry the sea, had not been brought up to be scooped up. " piscatorial old Xu says, do not have method, have always compare had done not have, you also do not catch a family.
This kind of net is provided exist extensively also in maritime space of our country Nanhai. In Hainan island coastal, the fisherman has ththe most popular selling norton internet antivirusis kind of net call " set net " , use at catching coastwise a few miscellaneous fish and shrimp kind.
Hainan saves Chen Jiming of chief engineer of aquatic product institute to say, it is with Nanhai exemple, catching means has a variety of kind such as dragnet, purse net, gill net, purse net and gill net are aimed at specific fish breed, and dragnet blow area is larger. Current, guangdong, Hainan has many ships to use dragnet this kind of catching means.
Attenuation of advanced resource of fishery of catching technology aggravate
"Without offspring net " infestation, probably firm firm ground gave piscatorial protectionism a slap. This kind of shrimp letting a fish " may you die without sons " the net is provided cause the people widespread doubt, what how many years cried can you last why did development predestined relationship go " drain the pond to get all the fish " degree?
Zhejiang saves ocean and Lin Dongyong of piscatorial bureau deputy director general to say: "Drain the pond to get all the fish " it is piscatorial resource acute those who decrease advocate because of. Go up century at the beginning of 80 time up to now, zhejiang is in the number of total horse power of fisher increased 4 times above, mean fishing intensity twice to increase; In addition, catching technologthe bethe best selling modern dining chairsst selling north face shirtsy is more advanced, original fisherman relies on briny observation school, rely on compass to discern direction, break ground should rely on handiwork, be replaced by advanced machine, instrument now.
Besides shocking " without offspring net " , lamplight round, report is caught also aggravate the attenuation of piscatorial resource. A fisherman says, arrived in the evening, hundreds of boats open an about a hundred small cup lamp, offshore and ghastly one, the fish has phototaxis, see light, can swim, "Without giving thought to greatly small fish, be arrested entirely came up. Be arrested entirely came up..
The so called boat that catch shrimp, use the net clean-out sea that holding dc of about a hundred bend over namely actually, catching the shrimp that come up is dead mostly, "Power is too great, give Sun Dou of shrimthe best spring poolp roe shrimp caught. " according to statistic, only stage city one ground, have boat of shrimp of on 1000 report.
Cross catch bound, illegally aggravate piscatorial resource is destroyed. Coastal fisherman expresses Zhejiang, catch these small fish, having a lot of is foreign vessel of the other place, also have many be " 3 without the boat " —— does not have boat name number, without shipping certificate, without port of registry. These illegal fisher often change work way arbitrarily, go to sea in closed season, destroy fish multiply to grow.
Because current fishery superintends a system to be opposite hard,the illegal fisher that crosses canton undertakes condemnatory, so the fisher of coastal province became " you steal me, I steal you " , often cross a bound to catch illegally, and often use " without offspring net " wait for method drain the pond to get all the fish, cause damage of resource of fishery of whole coastal waters.
Hainan saves Chen Jiming of chief engineer of aquatic product institute to express, "Without offspring net " run rampant in foreland, main reason is our country still does not have the use of laws of pair of fishing gear fishing to publish detailed regulation.
The net is provided ban with limits hopeful of formulary the end of the year comes on stage
Be faced with dried up with each passing day fishery resource, "Without offspring net " bwatch case openere current is one disaster after another more. The personage inside course of study thinks, protect the descendants of good fish, protect long earnings of the fisherman namely. Accordingly, "Without offspring net " more should by at an early date without offspring.
The sea has begun to the retaliation of drain the pond to get all the fish, zhejiang a lot of fishermans are initiative proposal " extend closed season " . Be in charge of company of branch, fishery and piscatorial itself, realize resource of fishery of the East China Sea had arrived " the most dangerous when " , need increases protective strength.
Wave of accord with of the member that Hainan saves survey of catching department of ocean and piscatorial office says, piscatorial net provides the Ministry of Agriculture to still be in with catalog definitely now in establishing a procedure, had opened a symposium at present, seek the opinion that saves fishery to be in charge of a branch each littoral again even, the end of the year publishs hopeful this year relevant policy or regulation, what stipulate the net is providi wanharrison hot spring dealt modern dining chairsed in detail is accurate use and ban with limits.
Chen Jiming suggests, the transition that solves this one problem to still need to continue to drive fishery thoroughly upgrades, accelerate a fisherman change the line of production be transferred to civilian work. It is to want reasonable catch, science catchs. Piscatorial resource will be annual grow naturally, catch to also want to be in reasonable range, because this catchs,should control intensity strictly. 2 it is coastal waters catchs should catch to high seas stage by stage transfer. 3 it is to reduce piscatorial population stage by stage, drive up from course of study " doorsill " , try every means promotes common fisherman to change the line of production be transferred to civilian work, raise the content of science and technology of piscatorial catching course of study.
"Undertake restrict and be condemnatoried to destroying the behavior of piscatorial resource and net to provide, execute the law the branch should act jointly the firm that to production, sale restricted net has undertakes condemnatory. " the part suffers visit piscatorial proposal, answer to take the lead by marine fishery branch, in the light of use destroy resource net to provide undertake associated executing the law to act greatly, give to violatimodern dining chairsng compasses net to provide confiscate, to using person give warning. And but the city of city of the groove guard management board of branch of accredit water Wu, maritime space, ground runs a department, authority is provided to this kind of net undertake condemnatory.
