Destructive Fishing

Increasing consumer demand for seafood, combined with concern over the health of our oceans, has led to many initiatives aimed at tackling destructive fishing practices and promoting the sustainability of fisheries. So, our aim was to develop a PCR-based technique for checking authenticity of fish fillets supplied in Tabriz (Iran). In present study, about 80 samples of frozen fish fillet with general trademarks including south fillet, excellent fillet and 40 samples of Javelin grunter fillet and Scomberomorus commerson fillets were collected from different chain markets all over the Tabriz. Lot Tolerance Per-cent Defective (LTPD) method was used in collecting the samples which is the low errors. Our research showed a higher rate of misbrandingand misla-beling found in markets with general names (85%) and specified names of Javelin grunter and Scomberomorus commerson (40%). Based on present study, the capacity of shark is high in mislabeling and fraud because of their situation in making steaks and fillet, low price in compared with other spe-cies and religious limitations.

Many destructive fishing practices are widely used at many sites of Central Travancore of Kerala, India. Most of these are indigenous methods practiced at high level to low level regions. It includes chemical poisons, plant poisons, fish traps, electric fishing etc. All these gears kill the fishes and their fries and fingerlings indiscriminately.  It is an endeavor to trace out the details of these harmful fishing methods.

The objective of this study is to find out and explain the destructive fishing practices occurred in Taka Bonerate National Park area and the factors that caused it. Data retrieval was conducted with in-depth interview techniques, literature studies and documents. The results showed that destructive fishing practices were still prevalent in the Taka Bonerate National Park area, both using chemicals (cyanide) and those using explosives (bombs) in fishing activities. The conclusions from this study are that fisheries destructive activities are generally not carried out individually but in groups, namely 3-4 people led by a captain. There are several contributing factors to the proliferation of destructive fishing practices in the small islands of Taka Bonerate National Park. Where they are still under guarded, and the conflicts of authority among the Taka Bonerate National Park management authorities, conflicts between fishermen, and availability of bombs and cyanides raw materials. The other are strong position of retainer and weak position of mustard in patron client relations between punggawa-sawi. The last factor but not least, that there are markets for them to sell the bombs and cyanide fishing.

Destructive Fishing

International agreements as well as European and national legislation prohibit exploitation and trading of a number of edible marine shelled molluscs, due to either significant declines in their populations or destructive fishing practices. However, enforcement of existing legislation in Greece is ineffective and many populations of “protected” species continue to decline, mainly due to poaching. The extent of illegal trading of protected bivalves and gastropods in Greek seafood restaurants was investigated by interviewing owners or managers of 219 such restaurants in 92 localities. Interviews were based on questionnaires regarding the frequency of availability in the menus and the origin of twenty-one species or groups of species, among which eight are protected - illegally exploited. Forty-two percent of the surveyed restaurants were found to serve at least one of the protected ¬- illegally exploited species. Among the illegally traded species, Lithophaga lithophaga, Pecten jacobaeus, and Pinnanobilis were served in a relatively high proportion of the surveyed restaurants (22.8%, 19.2%, and 16.4% respectively), outrunning many commercial species. In many cases these species were always or often available (11.4%, 4.6% and 5.0% respectively). There was substantial spatial variation in the proportion of restaurants that illegally served protected species with differing patterns for each species; very high proportions of illegal trading were observed in some marine regions (e.g., date mussels were served in >65% of the seafood restaurants along the coastline of Evvoikos Gulf). In most cases the illegally traded species were of local origin, while there was no finding of illegally imported molluscs from other countries. The strategy for enforcement of existing legislation should be greatly improved otherwise protection of shelled molluscs will remain ineffective.

Destructive Fishing

Coral reefs are a sundry subaqueous ecological community, combined with the calcium carbonate structures secreted by converting the carbon dioxide present in the water into limestone. The biotic portion of the coral reef is marine animal known as polyps that have resemblance with jellyfish. Unlike terrestrial environment, the marine component is tightly interdependent. Taking out one component or loss of from a system can have a devastating impact or undermine the entire marine ecosystem. Reefs specifically are a vital organism among underwater life which is dependent on corals and provide key microhabitat, shelter and breeding ground for thousands of species of fish, crustaceans, mollusks, etc. Coral reef possesses vital ethnobotanical properties, which cures asthma, arthritis, and even cancer. Apart from medicinal properties, further it provides 2/3rd of oxygen on earth. However, the destructive fishing practices, pollution and ocean acidification have endangered this kingdom and have led to the threatening of the entire fabric of the underwater life. As human beings are also dependent up to much extent for centuries, there is a high probability of being severely affected if the coral reef extinct leaving the seabed barren. Corals cover almost 1 % of the oceans present on earth, but the irony is 75 % of them are on a verge of extinction. Therefore, the present review focuses on its conservation, cultivation and significance of their application in the field of biomedical science.Keywords: Coral reef, endangered, ethnobotany, extinction, marine ecosystem, pollution.
