Many of the clinical tools used to evaluate mammalian health are not developed for use in fishes. As the aquaculture industry expands, there is an increasing need for improved diagnostic methods. There are few tools available to diagnose and monitor diseases on fishes. One such tool is the analysis of blood; it can help detect acute and chronic pathophysiological changes attributable to nutrition, water quality, toxicants and disease. One of the difficulties in assessing the state of health of natural fish population has been the paucity of reliable references of the normal condition. In pursuit to this goal, many fish physiologists have turned to studies of haematology. Haematological data are used routinely in health care of humans and domestic animals. Haematological evaluations are also gradually becoming a routine practice for determining health status in fish (Tavares-Dias et al., 2003; Ranzaini-Paiva et al., 2003; Cazenave et al., 2005). Only a few normal values for small number haematological parameters have been established for some teleosts, but these values range widely due to the lack of standardized collecting and measuring techniques (Blaxhall, 1972).

Chilika with its unique biodiversity wealth, ecological diversity and being known as an avian paradise is the pride of our wetland heritage and the first designated Indian Ramsar Site. The ecosystem services of Chilika are critical to the functioning of our life support system in general and livelihood of more than 0.2 million local fishers and other stakeholders in particular. It is also one of the few lakes in the world which sustain the population of threatened Irrawaddy Dolphin. Chilika also has a long history of its floral and faunal studies which begun since more than a century ago.

    Behavioral Evidence of Chemical Communication by Male Caudal Fin Organs of a Glandulocaudine Fish (Teleostei: Characidae)

Because this structure is present only in adult males, it is hypothesized that these cells secrete a reproduction-related pheromone. The hypothesis that the caudal organ releases chemicals that attract females is tested in Mimagoniates inequalis. In a Y-maze and an aquarium, females were attracted to a caudal organ extract and to water that was conditioned with caudal organ-bearing males, respectively, but not to caudal-fin lobe extract or water conditioned with males from which the caudal organs were removed (control stimuli). In tests with male-female pairs, there were no differences in the responses to caudal organ extract and male caudal organ-conditioned water, but the responses to both stimuli differed in relation to the controls. Male-female pairs engaged in fewer courtship events and more agonistic interactions than they did without chemical stimuli and with control stimuli. These results provide evidence for a possible pheromonal system in M. inequalis. The caudal organ is a specialized secretory structure that produces a chemical signal that attracts females and increases the aggressiveness of males.

Azevedo Setor de Ictiologia, Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, Rua Dr. Salvador França, 1427, 90690-000 Porto Alegre, RS, Brazil. ([email protected]) ABSTRACT. In this study, I investigated the reproductive biology of fish species from the family Characidae of the order Characiformes. I also investigated the relationship between reproductive biology and body weight and interpreted this relationship in a phylogenetic context. The results of the present study contribute to the understanding of the evolution of the reproductive strategies present in the species of this family. Most larger characid species and other characiforms exhibit a reproductive pattern that is generally characterized by a short seasonal reproductive period that lasts one to three months, between September and April. This is accompanied by total spawning, an extremely high fecundity, and, in many species, a reproductive migration. Many species with lower fecundity exhibit some form of parental care. Although reduction in body size may represent an adaptive advantage, it may also require evolutionary responses to new biological problems that arise. In terms of reproduction, smaller species have a tendency to reduce the number of oocytes that they produce. Many small characids have a reproductive pattern similar to that of larger characiforms. On the other hand they may also exhibit a range of modifications that possibly relate to the decrease in body size and the consequent reduction in fecundity.

    American Society of Ichthyologists and Herpetologists Board of Governors Meeting Student Union Building 207/209 - University of British Columbia Vancouver, British Columbia, Canada 8 August 2012 Maureen A. Donnelly Secretary Florida International University College of Arts & Sciences 11200 SW 8th St. - ECS 450 Miami, FL 33199 [email protected] 305.348.1235 1 July 2012 The ASIH Board of Governor's is scheduled to meet on Wednesday, 8 August 2012 from 5:00 – 7:00 pm in the Student Union Building, Rooms 207/209 at the University of British Columbia. President Beaupre plans to move blanket acceptance of all reports included in this book that cover society business for 2011 and 2012 (in part). The book includes the ballot information for the 2012 elections (Board of Governors Election and General Election held during the Annual Business Meeting). Governors can ask to have items exempted from blanket approval. These exempted items will be acted upon individually. We will also act individually on items exempted by the Executive Committee. Please remember to bring this booklet with you to the meeting. I will ship a few extra copies to Vancouver for the meeting. Please contact me directly (email is best - [email protected]) with any questions you may have. Please notify me if you will not be able to attend the meeting (if you have not contacted me yet) so I can share your regrets with the Governors. I will leave for Vancouver on 7 August so try to contact me before that date if possible. The Annual Business Meeting will be held on Sunday 12 August 2012 from 6:00 to 8:00 pm in The Gage Common Block (please consult the schedule for the room number for the meeting as it has not yet been determined).
