Title: Technical publication of Nigerian Institute for Oceanography and Marine Research (NIOMR) Lagos Nigeria Authors: Ayinla, O. A. Abstract: The Nigerian Institute for Oceanography and Marine Research (NIOMR) established in November 1975 by the Research Institute Establishment Order of 1975 has the responsibilities to conduct research into the resources and geological/geophysical, chemical and physical characteristics of the Nigerian territorial waters and the high seas. NIOMR also conducts research to fish utilization as well as Extension and Liaison Services. Since the establishment of NIOMR, a total of 35 occasional papers and 109 technical papers had been published to expose the research findings of the Institute to various stakeholders. These technical papers were previously published as standalone papers. In order to improve the quality, publication and circulation of scientific information from the Institute NIOMR’s Technical Committee was set up in June 2007. I am happy to note that the new Technical Publication Committee has coordinated the publication of this new NIOMR Technical Paper Series as volumes. Each Volume which may consist of 5 or more papers will be subsequently published on a half yearly basis. The papers in this new series have been critically peer reviewed both internally and by external scientists. I hope that with the release of this maiden technical paper series, NIOMR scientists will seize the opportunity to make their research findings available to the scientific community, educational, government and private stakeholders. It is my believe that this publication and subsequent editions, will further extend the frontiers of knowledge and contribute to the body of scientific information needed for the socio-economic development and sustainable management of Nigeria’s marine coastal environment and resources.

Title: The reproductive biology and culture of macrobrachium vollenhovenii (Herklots, 1857) and macrobrachium macrobrachion (Herklots, 1851) in Nigeria. Authors: Marioghae, I.E.; Ayinla, O.A. Abstract: Macrobrachium vollenhovenii and Macrobrachion, the two largest Macrobrachium species in Nigeria waters attain maximum adult sizes of 19cm and 13.5cm respectively. Male - female ration is approximately 1.1 for both species. Male dimorphism has been observed in M. macrobrachion but not in M. vollenhovenii. Both prawns breed throughout the year (usually in the brackish waters) with peaks in the rainy season. Although berried females of M. vollenhovenii occur in landlocked water bodies, rearing the larvae has so far been successful in brackish water. Bi-weekly spawning peaks occur in M. macrobrachion but are still to be verified for M. vollenhovenii. Induced spawning has been successful carried out for M. vollenhovenii by using a combination of pituitary hormone and changes in illumination, temperature and water level. Clutch size ranges from 1,000 - 10,000 for M. macrobrachion and 45,00 - 400,000 for M. vollenhovenii. Egg incubation takes 16-20 days in both species. Two culture trials using diets of 14% crude protein and agriculture by-products of unspecified composition, gave growth rates of 0.24g/day and 0.03g/day respectively.

Title: 1994 international beach clean up exercise at the bar beach Lagos, Nigeria. Authors: Awosika, L.F.; Folorunsho, R.; Isebor, C.; Adegbie, A.T.; Dublin-Green, C.O. Abstract: At the request of the United States of America Centre for Marine Conservation, the Nigeria Institute for Oceanography and Marine Research organised a beach clean up at the Bar Beach Lagos on September 24 1994. An International beach clean up is usually held on the last Saturday of every September during the COASTWEEK. On this day, volunteers all over the world participate in a beach clean up in an effort to collect data and information on the types and amounts of debri littering the world's beaches. Volunteers for the Bar Beach clean up of 1994 were drawn from all works of life and some Federal and States agencies. A total of 10,872 pieces of different kinds of debri weighing 531.1kg were collected during the clean up. Further analysis of the different debri showed that plastics constituted 37% of the debris collected on the Beach. Other items included paper, which amounted to 16%, metal 3%, foamed plastics, which amounted to 10%, rubber which, amounted to 7%, wooden pieces which amounted to 7%, broken glass which amounted to 7%, and cloth pieces which amounted to 3% of the total debris collected. In all, the data showed that the Bar Beach, which is the most popular tourist beach in Nigeria, is very dirty. The result of this exercise could be useful in the formulation of an effective beach and even coastal zone management policy.
