Wf.> hilve recorded the employment of mollusks, crustaceans, echinoderms, fishes, reptiles, and cetace<lns, and noted a high predominance of fishes over other aquatic animals. Asthma, bronchitis, stroke, and wounds arc the most usual illnesses treated by animal-based medicines. These results corroborate Marques' zoothcrapeutic universality hypothesis. According to him, all human cultures that prcscnt a developed medical system do use animals as medicines. Further studies are requested in order to estimate the existence of bioactive compounds of ph<lrmacological value in these bioresources.

  • The Weed That Feeds the North Atlantic
    DRIFTING PLANTS KNOWN AS SARGASSUM SUPPORT A COMPLEX AND AMAZING VARIETY OF MARINE LIFE. The Weed That Feeds the North Atlantic BY JAMES PROSEK PHOTOGRAPHS BY DAVID DOUBILET AND DAVID LIITTSCHWAGER 129 Hatchling sea turtles, like this juvenile log- gerhead, make their way from the sandy beaches where they were born toward mats of sargassum weed, finding food and refuge from predators during their first years of life. PREVIOUS PHOTO A clump of sargassum weed the size of a soccer ball drifts near Bermuda in the slow swirl of the Sargasso Sea, part of the North Atlantic gyre. A weed mass this small may shelter thousands of organisms, from larval fish to seahorses. DAVID DOUBILET (BOTH) 130 NATIONAL GEOGRAPHIC THE WEED THAT FEEDS THE NORTH ATLANTIC 131 ‘There’s nothing like it in any other ocean,’ says marine biologist Brian Lapointe. ‘There’s nowhere else on our blue planet that supports such diversity in the middle of the ocean—and it’s because of the weed.’ LAPOINTE IS TALKING about a floating seaweed known as sargassum in a region of the Atlantic called the Sargasso Sea. The boundaries of this sea are vague, defined not by landmasses but by five major currents that swirl in a clockwise embrace around Bermuda. Far from any main- land, its waters are nutrient poor and therefore exceptionally clear and stunningly blue. The Sargasso Sea, part of the vast whirlpool known as the North Atlantic gyre, often has been described as an oceanic desert—and it would appear to be, if it weren’t for the floating mats of sargassum.

  • Diet Composition of Juvenile Black Grouper (Mycteroperca Bonaci) from Coastal Nursery Areas of the Yucatán Peninsula, Mexico
    BULLETIN OF MARINE SCIENCE, 77(3): 441–452, 2005 NOTE DIET COMPOSITION OF JUVENILE BLACK GROUPER (MYCTEROPERCA BONACI) FROM COASTAL NURSERY AREAS OF THE YUCATÁN PENINSULA, MEXICO Thierry Brulé, Enrique Puerto-Novelo, Esperanza Pérez-Díaz, and Ximena Renán-Galindo Groupers (Epinephelinae, Epinephelini) are top-level predators that influence the trophic web of coral reef ecosystems (Parrish, 1987; Heemstra and Randall, 1993; Sluka et al., 2001). They are demersal mesocarnivores and stalk and ambush preda- tors that sit and wait for larger moving prey such as fish and mobile invertebrates (Cailliet et al., 1986). Groupers contribute to the ecological balance of complex tropi- cal hard-bottom communities (Sluka et al., 1994), and thus large changes in their populations may significantly alter other community components (Parrish, 1987). The black grouper (Mycteroperca bonaci Poey, 1860) is an important commercial and recreational fin fish resource in the western Atlantic region (Bullock and Smith, 1991; Heemstra and Randall, 1993). The southern Gulf of Mexico grouper fishery is currently considered to be deteriorated and M. bonaci, along with red grouper (Epinephelus morio Valenciennes, 1828) and gag (Mycteroperca microlepis Goode and Bean, 1880), is one of the most heavily exploited fish species in this region (Co- lás-Marrufo et al., 1998; SEMARNAP, 2000). Currently, M. bonaci is considered a threatened species (Morris et al., 2000; IUCN, 2003) and has been classified as vul- nerable in U.S. waters because male biomass in the Atlantic dropped from 20% in 1982 to 6% in 1995 (Musick et al., 2000). The black grouper is usually found on irregular bottoms such as coral reefs, drop- off walls, and rocky ledges, at depths from 10 to 100 m (Roe, 1977; Manooch and Mason, 1987; Bullock and Smith, 1991; Heemstra and Randall, 1993).

In extreme cases, when fishing pressure is high, aggregations can dwindle and even cease to form, sometimes within just a few years. Whether or not they will recover and what the long-term effects on the fish population(s) might be of such declines are not yet known. We do know, however, that healthy aggregations tend to be associated with healthy fisheries. It is, therefore, important to understand and better protect this critical part of the life cycle of aggregating species to ensure that they continue to yield food and support livelihoods. Why a Handbook? As fishing technology improved in the second half of the twentieth century, engines came to replace sails and oars, the cash economy developed rapidly, and human populations and demand for seafood grew, the pressures on reef fishes for food, and especially for money, increased enormously.

    A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.
