1. Of the five by-catch species, four became progressively smaller over the 17-year period, by 25%-57%, suggesting the fisheries were driving down the size of the fish that remain in the oceans.

2. The composition and monthly variation of by-catch were analyzed on the basis of production investigation and data collected by fishing vessels in 2005 by Microsoft Excel.

3. Improving fishing methods to reduce "by-catch" of other species, such as endangered sea turtles.

4. In Alaska, officials forced fisheries to cut their by-catch by threatening to close them if they failed to do so, an example that Dr Myers believes other fishing regions should follow.

5. Discards of "by-catch" -- which are not only wasteful but can have broader environmental impacts on both specific fish stocks and entire ecosystems -- have been a concern of FAO's for years.

6. "There have already been some dramatic results, with by-catch being reduced by as much as 50 percent in some cases," reports Turner.

7. Fisheries in some parts of the world, notably Alaska, have developed ways to cut their by-catch by using new technology and switching fishing grounds.

8. But unfortunately Molas, even though they don't school, they still get caught in nets as by-catch.

9. With less selectivity in trawling, there will be inevitably much by-catch and many discards during catching the target species.

10. Based on production investigation and sampling data by fishing vessel in 2005, composition and monthly variation of by-catch were analysed with data analysis tool of Microsoft Excel.

11. Trawl sorting grids can effectively enhance the selectivity of trawl, reduce by-catch and discards, protect fish resources, which are compulsively used in many countries by legislation.

12. This will supply a scientific base for the research about the separating device. In 2000 many data about protecting fishery were consulted[sentencedict .com], especially the separating devices for by-catch.

13. There, fishermen might earn as little as 1US$ a day, and by-catch is often not discarded -- boat owners let their crews sell it for processing to meet demand for human and aquaculture consumption.

14. On the basis of data obtained in the shrimp trawl ecological survey for Tonggu Waterway of Pearl River Estuary, we analyzed composition of by-catch for the fishery in this paper.

15. A lot of skates and rays and the chimaeras are not as charismatic as white sharks or whale sharks or a manta ray, but these things are probably taken in far greater numbers in terms of by-catch.

16. And unfortunately, they make up a large portion of the California by-catch -- up to 26 percent of the drift net.
