  • Chapter 11 the Biology and Ecology of the Oceanic Whitetip Shark, Carcharhinus Longimanus
    Chapter 11 The Biology and Ecology of the Oceanic Whitetip Shark, Carcharhinus longimanus Ramón Bonfi l, Shelley Clarke and Hideki Nakano Abstract The oceanic whitetip shark (Carcharhinus longimanus) is a common circumtropical preda- tor and is taken as bycatch in many oceanic fi sheries. This summary of its life history, dis- tribution and abundance, and fi shery-related information is supplemented with unpublished data taken during Japanese tuna research operations in the Pacifi c Ocean. Oceanic whitetips are moderately slow-growing sharks that do not appear to have differential growth rates by sex, and individuals in the Atlantic and Pacifi c Oceans seem to grow at similar rates. They reach sexual maturity at approximately 170–200 cm total length (TL), or 4–7 years of age, and have a 9- to 12-month embryonic development period. Pupping and nursery areas are thought to exist in the central Pacifi c, between 0ºN and 15ºN. According to two demographic metrics, the resilience of C. longimanus to fi shery exploitation is similar to that of blue and shortfi n mako sharks. Nevertheless, reported oceanic whitetip shark catches in several major longline fi sheries represent only a small fraction of total shark catches, and studies in the Northwest Atlantic and Gulf of Mexico suggest that this species has suffered signifi cant declines in abundance. Stock assessment has been severely hampered by the lack of species-specifi c catch data in most fi sheries, but recent implementation of species-based reporting by the International Commission for the Conservation of Atlantic Tunas (ICCAT) and some of its member countries will provide better data for quantitative assessment.

  • Lake Huron Scuba Diving
    SOUTHERN LAKE ASSESSMENT SOUTHERN RECREATION PROFILE LAKE Scuba Diving: OPPORTUNITIES FOR LAKE HURON ASSESSMENT FINGER LAKES SCUBA LAKES FINGER The southern Lake Huron coast is a fantastic setting for outdoor exploration. Promoting the region’s natural assets can help build vibrant communities and support local economies. This series of fact sheets profiles different outdoor recreation activities that could appeal to residents and visitors of Michigan’s Thumb. We hope this information will help guide regional planning, business develop- ment and marketing efforts throughout the region. Here we focus on scuba diving – providing details on what is involved in the sport, who participates, and what is unique about diving in Lake Huron. WHY DIVE IN LAKE HURON? With wildlife, shipwrecks, clear water and nearshore dives, the waters of southern Lake Huron create a unique environment for scuba divers. Underwater life abounds, including colorful sunfish and unusual species like the longnose gar. The area offers a large collection of shipwrecks, and is home to two of Michigan’s 12 underwater preserves. Many of the wrecks are in close proximity to each other and are easily accessed by charter or private boat. The fresh water of Lake Huron helps to preserve the wrecks better than saltwater, and the lake’s clear water offers excellent visibility – often up to 50 feet! With many shipwrecks at different depths, the area offers dives for recreational as well as technical divers. How Popular is Scuba Diving? Who Scuba Dives? n Scuba diving in New York’s Great Lakes region stimulated more than $108 In 2010, 2.7 million Americans went scuba A snapshot of U.S.

  • Ribbon Reefs Dive Site Info
    Ribbon Reefs - Dive Sites The Cod Hole The world-famous Cod Hole is home to numerous Potato Cod. These huge fish are quite used to divers, offering the chance to get up close and personal, and are quite willing to pose for a photo whilst visiting one of the many cleaning stations. Whilst usually docile and relaxed, the Cod feed allows divers to see the spectacle of these fish feeding in action. The shallows of Cod Hole offer excellent coral life to explore and the chance to search for many hidden treasures. Follow the terraced reef down for the chance to witness pelagic fish on their way past. Though susceptible to current on an incoming tide, this makes for an excellent drift dive.

    AndreaInterview with Donati — Pioneering Technical Diving on Ponza for 30 Years Andrea Donati (left) and his partner, Daniela Spaziani, run Ponza Diving, which is located in the main harbour (above) of Ponza Island in Italy. In my line of work as a dive industry professional, I attend a lot of dive shows and get to meet a lot of people, most of them nice and interesting in various ways. It was also at a dive show in Italy, many years ago, that I first met Andrea Donati and his partner, Daniela Spaziani, of Ponza Diving. I clearly remember my first impression of how sympathetic, unpretentious and genuine the two came across, which scores a lot of points in my book. They appeared competent and organised, and with their operation located in one of the most picturesque locations I have ever seen, it did not take any arm twisting to lure me down there for a visit.
