Climatic Effects on Lake Basins. Part I: Modeling Tropical Lake Levels
15 JUNE 2011 R I C K O E T A L . 2983 Climatic Effects on Lake Basins. Part I: Modeling Tropical Lake Levels MARTINA RICKO AND JAMES A. CARTON Department of Atmospheric and Oceanic Science, University of Maryland, College Park, College Park, Maryland CHARON BIRKETT Earth System Science Interdisciplinary Center, University of Maryland, College Park, College Park, Maryland (Manuscript received 28 December 2009, in final form 9 December 2010) ABSTRACT The availability of satellite estimates of rainfall and lake levels offers exciting new opportunities to estimate the hydrologic properties of lake systems. Combined with simple basin models, connections to climatic variations can then be explored with a focus on a future ability to predict changes in storage volume for water resources or natural hazards concerns. This study examines the capability of a simple basin model to estimate variations in water level for 12 tropical lakes and reservoirs during a 16-yr remotely sensed observation period (1992–2007). The model is constructed with two empirical parameters: effective catchment to lake area ratio and time delay between freshwater flux and lake level response. Rainfall datasets, one reanalysis and two satellite-based observational products, and two radar-altimetry-derived lake level datasets are explored and cross checked. Good agreement is observed between the two lake level datasets with the lowest correlations occurring for the two small lakes Kainji and Tana (0.87 and 0.89). Fitting observations to the simple basin model provides a set of delay times between rainfall and level rise ranging up to 105 days and effective catchment to lake ratios ranging between 2 and 27. -
Morphological Development of Embryos and Juveniles in the Mozambique Tilapia, Oreochromis Mossambicus As a Direct Developmental Fish Under Rearing Conditions
SUISANZOSHOKU 51(3), 295-306 (2003) Morphological Development of Embryos and Juveniles in the Mozambique Tilapia, Oreochromis mossambicus as a Direct Developmental Fish under Rearing Conditions Katsunori TACHIHARA*1,2 and Emi OBARA*1 (Accepted June 17, 2003) Abstract: The Mozambique tilapia, Oreochromis mossambicus is one of the species introduced to Okinawa Island. This species breeds widely in the rivers of the island. In order to understand the biological aspects of O. mossambicus under the natural conditions of the island, a detailed observa- tion of early morphological development was done under rearing conditions. The development of O . mossambicus was studied; it consisted of an embryonic phase of approximately 88 hours and 30 minutes, a free embryonic phase of about 12 days, followed by the juvenile period. The embryo became free-swimming on the sixth day of the free embryonic phase. The osteological develop- ment using enzyme-cleared specimens indicated that after reaching the juvenile stage, develop- ment of almost basic bones was complete 25 days after hatching. Key words: Oreochromis mossambicus; Direct development; Early life history; Okinawa Island The Mozambique tilapia, Oreochromis mos- sambicus is a freshwater fish, which has been Materials and Methods introduced to Okinawa Island1-3). The species is endemic to southern African rivers, lagoons Three mouthbreeding females (122.7 to and lakes, and ranges from the lower Zambezi 124.7 mm in standard length) harboring newly system in the north to the Bushmans River fertilized ova were collected from the Onaha in the south4). This species was introduced to River, Nishihara, Okinawa, Japan, on June 4, Okinawa Island in 1954 from Taiwan as a source 1997, using a cast net (mesh size: 1•~1 cm). -

(2019). Diversity and length-weight relationships of Blenniid Species (Actinopterygii, Blenniidae) from Mediterranean Brackish Waters in Turkey. Aquatic Sciences and Engineering, 34(3), 96-102. ABSTRACT This study aims to determine the species composition and range of Mediterranean Blennies (Ac- tinopterygii, Blenniidae) occurring in river estuaries and lagoon systems of the Mediterranean coast of Turkey, and to characterise the length–weight relationship of the specimens. A total of 15 sites were surveyed from November 2014 to June 2017. A total of 210 individuals representing 3 fish species (Rusty blenny-Parablennius sanguinolentus, Freshwater blenny-Salaria fluviatilis and Peacock blenny-Salaria pavo) were sampled from five (Beşgöz Creek Estuary, Manavgat River Es- tuary, Karpuzçay Creek Estuary, Köyceğiz Lagoon Lake and Beymelek Lagoon Lake) of the locali- ties investigated. The high juvenile densities of S. fluviatilis in Karpuzçay Creek Estuary and P. sanguinolentus in Beşgöz Creek Estuary were observed. Various threat factors were observed in five different native habitats of Blenny species. The threats on the habitat and the population of the species include the introduction of exotic species, water ORCID IDs of the authors: pollution, and more importantly, the destruction of habitats.

Genetic Resources for Aquaculture: Status and Trends
109 Genetic resources for aquaculture: status and trends Roger S.V. Pullin 7A Legaspi Park View, 134 Legaspi Street, Consultant, Philippines 1. SUMMARY Aquaculture, the farming of aquatic plants and animals, has grown consistently since 1970, when it provided only 3.9 percent of world fish supply. In 2004, global production of farmed fish (mainly crustaceans, molluscs and finfish) was over 45 million tonnes, comprising about 32 percent of total world fish supply, while the total production of farmed seaweeds for food and extraction of chemicals, was about 13.9 million t. Aquaculture also provides increasing proportions of the world’s supply of ornamental aquatic organisms. Over 90 percent of aquaculture takes place in developing countries, where it has high importance for poor people in terms of nutrition and livelihoods and where further responsible development of aquaculture, integrated with other natural resource use, has high potential for future growth. Based upon statistics submitted to FAO by its member States, about 84 percent of farmed fish production comes from Asia, with 67 percent coming from the Peoples’ Republic of China. However, aquaculture is increasing in importance in all developing regions and is expected to provide about 50 percent of world food fish supply within the next 20 years. The future of aquaculture will depend in large measure upon the effective management of the genetic resources for farmed aquatic plants (PGR) and farmed fish (FiGR), as well as those for the organisms that provide their food and ecosystem services. Fish farms are agroecosystems and aquatic genetic resources for aquaculture on farms are part of agrobiodiversity. -

Mozambique tilapia, Oreochromis mossambicus. [http://ja.wikipedia.org/wiki/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB:Oreochromis_mossambicus_ by_NPS.jpg, downloaded 5 October 2012] TRAITS. Oreochromis mossambicus is a medium sized, laterally compressed fish that has long dorsal fins with 10-13 rays and spines (Froese & Pauly 2007). Its scales are large along the snout and fore head and become smaller along the body (Luna 2012). The coloration is a dull greenish yellow with weak banding pattern along the body (Froese & Pauly 2007). The adults range in size from 25 cm in the female to approximately 35 cm in the male. The male has an average weight of 2.5 pounds and the female ranges from 1.8-2 pounds at its maximum weight (Froese & Pauly 2007). O. mossambicus exhibits sexual dimorphism, the best descriptors are the premaxilla width, anal fin height and snout length; traits vital for agonistic displays, nesting and fighting (Oliveira & Almeda 1995). The size and coloration vary in captivity and with its diet. Some O. mossambicus look almost black in colour; females, non-breeding males and fry/ juveniles have a silvery colour on the scales (Luna 2012). O. mossambicus can live in both brackish and salt water and can survive a wide range of temperatures (Froese & Pauly 2007), and can live up to 11 years (Luna 2012).

Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.
