Welcome from IAS President Dr. Melinda Coogan As scientists, we are living at a time of significant contributions and vital importance. Your support of the 129th annual meeting of the Iowa Academy of Science is crucial to the dissemination of valuable information and the support of young Iowa scientists whose enthusiasm inspires even the most severe curmudgeons. Thanks to the presence of Iowa’s superior research and educational institutions, we have a unique opportunity to be at the forefront of current and future scientific breakthroughs and discoveries. Since 1875, the Iowa Academy of Science has provided leadership in these endeavors, and I would personally like to extend a warm welcome to you, your colleagues, and students as we continue this 145-year-old tradition. It is a pleasure to return to the University of Northern Iowa campus for our 129th annual meeting, and I hope your time in Cedar Falls initiates and refreshes friendships and excitement for science as you reflect upon the positive impact IAS has had on you, Iowa, and our global community.

India has a coastline of 8,118 km, with an exclusive economic zone (EEZ) of 2.02 million sq km and a continental shelf area of 468,000 sq km, spread across 10 coastal States and seven Union Territories, including the islands of Andaman and Nicobar and Lakshadweep. Indian coastal waters are extremely diverse attributing to the geomorphologic and climatic variations along the coast. The coastal and marine habitat includes near shore, gulf waters, creeks, tidal flats, mud flats, coastal dunes, mangroves, marshes, wetlands, seaweed and seagrass beds, deltaic plains, estuaries, lagoons and coral reefs. There are four major coral reef areas in India-along the coasts of the Andaman and Nicobar group of islands, the Lakshadweep group of islands, the Gulf of Mannar and the Gulf of Kachchh . The Andaman and Nicobar group is the richest in terms of diversity.

  • Print Version Diving in Lembeh Strait, Northern Sulawesi, Indonesia Copyright Teresa Zubi
    Print version diving in Lembeh Strait, Northern Sulawesi, Indonesia Copyright Teresa Zubi www.starfish.ch Lembeh strait is one of the most interesting marine habitats that I know, a real macro paradise and a great place to do scuba diving! I first dived here in 1994 but have come back many times and must have done over a two hundred dives only here, so I know the place rather well. There are over 50 dive sites around the Lembeh strait, most of them are either sandy areas or small reefs. Don't expect spectacular walls or huge reefs, here you are doing so called muck diving - searching for the rare and the special (for more good places for muck diving look at Secret Bay and Padang Bai in Bali, Dauin in Negros, Cabilao in Bohol situated in the Philippines and Mabul in Borneo). I am a frogfish specialist and the Lembeh strait is just full of them. But its also a good place to see other shy critters such as the mimic octopus, the flamboyant cuttlefish, harlequin shrimps, wonderpus, skeleton shrimps and many nudibranchs. The fish at this place are also a collection of weirdoes: Ambon scorpionfish (Pteroidichthys amboinensis), stonefish, sea robins, stargazers, devil fish and even the weedy scorpionfish (Rhinopias frondosa). There are also beautiful seahorses (we counted at least 7 different species, pygmy and others), pegasus, ghost pipefish and the endemic Banggai cardinalfish. Although most divers come here for the muck diving, Lembeh has much more to offer. Specially around Lembeh island there are some small but very beautiful coral reefs and at the northern tip at Batu Kapal the currents attract large pelagics like mackerels and sharks.There are also four beautifully covered wrecks, two of them large and all within limits for recreational diving.

Al-Shuaily and Amal Al Mujaini Department of Marine Science and Fisheries, College of Agricultural and Marine Sciences, P.O. Box 34, Al-Khod 123, Muscat, Sultanate of Oman [email protected] Abstract. The current work presents a comprehensive checklist of the Omani fish species. The different fish samples have been collected since the establishment of the Department of Marine Science and Fisheries (MSAF) in 1986. The fish samples identified by the MSAF were compared with the most recent published book on the Coastal Fishes of Oman. The number of Omani fishes (from both fresh water and sea water) totalled 1179, distributed in 527 genera, 165 families and 37 orders. Under the Chondrichtyes, the most diverse family was Carcharhinidae with a total of 25 species and 8 genera. The Carcharhinidae species comprised 27% of the total species identified under the Chondriichtyes. The second most diverse family was the dasyatidae with 10 species (11%) and 5 genera. Under the Ostiecthyes, the most diverse three families were the gobiidea with 37 genera and 69 species, the labridae with 26 genera and 63 species, and finally the carangidea with 20 genera and 54 species. The family and English names for the most popular families are provided as well. Keywords: Oman, fishes Introduction Oman has a very long coastline compared to its neighbouring gulf countries.

Corresponding author: *E-mail: [email protected] Abstract An annotated checklist of the fish species of the Madagascar EEZ (southwestern Indian Ocean) comprises a total of 1,798 species in 247 families. 158 species are recorded from Madagascar for the first time. The majority of the species is autochthonous; 28 species have been introduced, mainly in freshwater habitats. The fish fauna is mostly marine (95.4% of the total number of native fish species), with the Gobiidae, Labridae, Serranidae, Pomacentridae and Apogonidae being the families with most representatives; among the 90 native freshwater fish species (adults mainly occurring in freshwater), the Cichlidae are the dominating family, but there are also two endemic families, the Bedotiidae (16 species) and Anchariidae (6 species). The fish fauna at Madagascar is typical for offshore, high islands in the southwestern Indian Ocean.

    U.S. DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE Pacific Islands Regional Office 1601 Kapiolani Blvd., Suite 1110 Honolulu, Hawaii 96814-4700 (808) 944-2200 ● Fax (808) 973-2941 Environmental Assessment for Annual Catch Limit Specifications and Accountability Measures for Pacific Islands Coral Reef Ecosystem Fisheries in 2012 and 2013 Including a Regulatory Impact Review December 13, 2011 Responsible Agency: Pacific Islands Regional Office (PIRO) National Marine Fisheries Service (NMFS) National Oceanic and Atmospheric Administration (NOAA) Responsible Official: Michael D. Tosatto Regional Administrator NMFS PIRO 1601 Kapiolani Blvd., Suite 1110 Honolulu, HI 96814 (808) 944-2200 Responsible Council: Western Pacific Fishery Management Council 1164 Bishop St., Suite 1400 Honolulu, HI 96813 Contact: Kitty M. Simonds Executive Director (808)522-8220 Abstract NMFS proposes to specify an annual catch limit (ACL) and accountability measures (AM) for each coral reef ecosystem stock and stock complex of management unit species (MUS) in American Samoa, Guam, the Northern Mariana Islands, and Hawaii. The ACLs and AMs would be applicable in fishing years 2012 and 2013 which begin January 1 and end December 31, annually. The purpose of the action is to comply with provisions of the fishery ecosystem plans (FEP) for American Samoa, the Mariana Archipelago, and Hawaii which require NMFS to specify an ACL for each stock and stock complex in western Pacific coral reef ecosystem fisheries and implement AMs that prevent ACLs from being exceeded, and correct or mitigate overages of ACLs if they occur. Given the number of individual coral reef ecosystem stocks and stock complexes in each island area, individual species were aggregated into higher taxonomic groups, generally at the family level.
