鱼虱不能吃。
鱼虱的腹面有许多倒剌，能用来在鱼体上不断爬行，刺死鱼体，吸吮鱼血，引起鱼种大批死亡。在温暖的南方（水温16-30℃），一年四季均可发生。长江流域一带，每年6-8月为流行盛期。鱼虱对寄主年龄无严格的选择性，对大鱼主要是妨碍生长，一般不引起死亡，但对鱼种危害很大，少量寄生就能引起死亡。

4. 危害海洋生物的新闻
目前已经有很多的海洋生物因为垃圾而死亡，尤其是各种塑料垃圾。当下，塑料已经成为了海洋中所发现的第一大类垃圾。对此，有一家非营利组织就表示，从海滩和海洋收集到的所有垃圾中，塑料垃圾占了85%左右，放眼望去，看到的都是塑料瓶和塑料袋。这家非营利组织正在全球150多个国家组织海岸清理活动，所以这一数字是相对可靠的。
另外，也有相关机构做过统计，每年约有800万吨塑料垃圾进入海洋，全部加起来可以绕地球420圈，这无疑是一个令人吃惊的数字。现实生活中，许多人都不重视对塑料垃圾，习惯性的将塑料垃圾到处乱扔，特别是一些在海滩边上游玩的人，当喝完饮料后，一般都是将塑料瓶直接扔进海里。此外，还有各种各样的塑料袋也不例外，很少会有人专门收集好放进垃圾桶，基本上都是随意丢弃。而这些塑料垃圾最终都被冲入海洋中。
塑料垃圾的危害是很大的，最大的一个问题就是威胁海洋生物的生命。目前，已经有不少海洋生物因为塑料垃圾而失去了生命，对此，有科研机构曾做过研究，认为塑料将会威胁至少600种不同的海洋生物。比如棱皮龟，经常将塑料袋误认为可食的海蜇，从而吞进肚子里，由于无法消化，最终丧命。还有信天翁和海燕等在内的90%的海鸟，也通常会误食塑料，由此导致的结果也不例外。预计到2050年，这一数字将会上升到100%，意味着所有的海鸟都会吃下塑料，并因此丧命。
扔进海洋的塑料垃圾并不会自行消失，而是只能依靠降解，但通常情况下，需要400年的时间才能完全降解。对海洋生物而言，这就意味着一辈子，很有可能活不到塑料垃圾完全降解的那一天。如今，海洋中的塑料垃圾日益增多，不断侵占了海洋生物的生存空间，如果再不做出改变，那么死亡灭绝就是海洋生物唯一的结局。

海洋污染英语作文三：Sea pollution
Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.
In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.
Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).
This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.
海洋污染英语作文四：Sea Pollution
Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.
The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.
The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.
海洋污染英语作文五：Polluting the seas
The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.
In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.
As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.
