Ovo istraživanje obuhvatilo je populacije iz jezera Visovac na Krki i jezera Torak na Čikoli te populaciju gornjeg toka Čikole u Hrvatskoj i kanala Ždralovac u BiH. Terenski dio istraživanja proveden je od prosinca 2013. godine do lipnja 2016. godine te su obrađene ukupno 264 jedinke. Jedinke iz različitih populacija međusobno su uspoređene na temelju morfologije (morfometrija, meristika i vanjski izgled) i ekologije (dužinsko-maseni odnosi, razmnožavanje, prehrana, starost, rast i smrtnost), a rezultati pokazuju da jedinke iz gornjeg toka rijeke Čikole dosežu manje duljine tijela i manju starost te imaju lošije kondicijsko stanje i manji reproduktivni uspjeh od jedinki iz jezerskih sustava. Dobivene razlike rezultat su različitih uvjeta staništa na kojem pojedine populacije žive. Također, rezultati ukazuju na važnost zaštite oštrulja i njegovog staništa, naročito povremenih vodotoka, koji predstavljaju njegovo primarno stanište.

This research surveyed populations from Croatia (from lake Visovac on river Krka, lake Torak on river Čikola, and from upper river Čikola) and B&H (canal Ždralovac). The field work was carried out from December 2013 to June 2016 during which 264 specimens were caught. Individuals from different populations were compared based on morphology (morphometrics, meristics, external appearance) and ecology (length-weight relationships, reproduction, diet, age, growth, mortality). The results show that individuals from the upper part of river Čikola have smaller body size, shorter life-span, lower condition, and lower reproductive success than individuals from lake systems. Observed differences are the result of different habitats in which these populations live. Also, the results show the importance of protecting the barbelgudgeon and its habitat, especially temporary streams which are its primary habitat.

Duplication of genetic material is clearly a major route to genetic change, with consequences for both evolution and disease. A variety of forms and mechanisms of duplication are recognised, operating across the scales of a few base pairs upto entire genomes. With the ever-increasing amounts of gene and genome sequence data that are becoming available, our understanding of the extent of duplication is greatly improving, both in terms of the scales of duplication events as well as their rates of occurrence. An accurate understanding of these processes is vital if we are to properly understand important events in evolution as well as mechanisms operating at the level of genome organisation. Here we will focus on duplication in animal genomes and how the duplicated sequences are distributed, with the aim of maintaining a focus on principles of evolution and organisation that are most directly applicable to the shaping of our own genome.

  • Morphological Changes During Early Development of Endangered Golden Mahseer Tor Putitora
    Journal of Coldwater Fisheries 1(1):65-73, 2018 Morphological changes during early development of endangered golden mahseer Tor putitora KISHOR KUNAL, DEBAJIT SARMA, DEEPJYOTI BARUAH, PARVAIZ AHMAD GANIE ICAR-Directorate of Coldwater Fisheries Research, Bhimtal-263136, Nainital, Uttarakhand, India E-mail: [email protected] ABSTRACT Embryonic development of golden mahseer eggs were completed within 94-120 hours after fertilization at an ambient temperature of 20o C ± 2o C. The first cleavage occurs about 3hours post fertilization, with cleavage interval of about 35 minutes. The blastula period last from 6h 45m to 12h 10m post fertilization. During this period; the embryo enters midblastula transition (MBT), the yolk syncytial layer (YSL) forms, and epiboly begins, which continues till gastrulation period. The gastrulation period generally lasts from 16h 30m to 36h. Embryonic development was completed within 94-120 hours post-fertilization at 20º C ± 2º C. The present study provides preliminary insight about the early development progression in Golden mahseer, which can help in developing better rearing strategies for early larval rearing to achieve better survival and eventually leading to population enhancement in natural environment. Keywords: Embryo, Larvae, Development, Golden mahseer Introduction eggs enclosed in a hard and complex eggshell (chorion), which is formed by protein components organized into a Golden mahseer (Tor putitora) is one of the well-known complex structure. This structure plays an essential role in large freshwater game fish of Mountain Rivers and lakes control of the relation between the external and the internal of most Trans-Himalayan countries. It is one of the most- egg environments. It allows for respiratory gas diffusion, sought after species providing the main fishery in the uplands provides mechanical protection and thermal insulation, and all along the Himalayan belt extending from Kashmir in the permits sperm entry (Hamodrakas, 1992).

The structure and the embryo - genetic role of eggs and egg membranes of Ancistrus dolichopterus (Actinopterygii: Siluriformes: Loricariidae). Acta Ichthyol. Piscat. 41 (3): 223–227. Background. Bushymouth catfish, Ancistrus dolichopterus Kner, 1854 has raised interest among ornamental fish keepers. Its natural populations are seriously threatened by fishing pressure. The reproduction of this species is difficult to perform (in captivity) and to observe because it occurs at night in shaded areas—most frequently in hiding spots. This study was intended to describe the eggs and their membranes of bushymouth catfish known to provide a parental care during egg development. A special focus of this study was directed towards the microstructure of membranes protecting life cells, and known to be impacted by the environmental conditions the egg morphometric analysis, as well as embryonic development. Materials and methods. The material for the study consisted of the eggs of 3 pairs of bushymouth catfish obtained as a result of their spawning in an aquarium culture. The fertilised eggs were incubated at a constant temperature of 24 ± 0.2°C in water of hardness 17°n, pH 6.5.

  • The Bitterling–Mussel Interaction As a Test Case for Co-Evolution
    Journal of Fish Biology (2003) 63 (Supplement A), 84–104 doi:10.1046/j.1095-8649.2003.00209.x,availableonlineathttp://www.blackwell-synergy.com The bitterling–mussel interaction as a test case for co-evolution S. C. MILLS*,† AND J. D. REYNOLDS* Centre for Ecology, Evolution and Conservation, School of Biological Sciences, University of East Anglia, Norwich NR4 7TJ, U.K. The European bitterling Rhodeus sericeus (Cyprinidae) spawns in the gills of freshwater mussels (Unionidae) and shows some obvious adaptations to this type of spawning, such as the development of an ovipositor. Furthermore, recent studies have shown that the fish avoid species of mussels that have a high likelihood of ejecting their eggs prematurely. This leads to the question of whether the interaction between bitterling and mussels could represent a case of co-evolution, involving evolutionary responses by both species to selection imposed by the other. The evidence for and against co-evolution is reviewed, incorporating new results from two sets of experiments designed to test for adaptive choices by bitterling according to the mussels’ sex and reproductive state, as well as a preliminary study of potential benefits for mussels from exposure to bitterling. Host preferences by bitterling, both among and within mussel species, may indeed have evolved in response to differences in benefits for offspring survival. There is no evidence yet for any benefits to mussels from receiving eggs, whereas there are costs due to reduced ventilation rates when the gills contain bitterling eggs. While there are differences among mussel species and individuals in their tendency to reject bitterling embryos, these differences do not provide strong evidence for co-evolution.

Volume 1, Issue 4 (Nov. - Dec. 2012), PP 49-51 www.iosrjournals.org Ultra Structure Study of egg membrane in Osteobrama belangeri Val. 1K.Dinesh Singh, 2Mrs.W.Mema Devi 1Faculty of Science, CMJ University Shillong 793003 Meghalaya 2Associate Professor, G P Women’s College Imphal 795001 Manipur Abstract: Osteobrama belangeri (Valenciennes) is a highly prized endemic medium carp available in Yunan province of China, Myanmar and Manipur (North Eastern part of India). The fish attains sexual maturity in 2+ years (200 – 25 g. body weight). Investigation of the fine structure of the egg envelope and micropyle of unfertilized spawned eggs of Osteobrama belangeri using Scanning Electron Microscope (SEM) was made. The surface of the egg membrane showed regularly arranged pores. The micropyle is a type II consisting of the flat pit with diameter of micropyle 11 µm to 12 µm and a long canal narrowing into a distinct canal. The surface of zona radiata was rough with a uniform distribution of round pores with little larger pores around the micropyle region. Key words: chorion, micropyle, reproduction, Osteobrama belangeri, fertilization. I. Introduction: Osteobrama belangeri is known as Pengba in Manipur and Nga-bpe-oung in Myanmar. It was declared as State fish of Manipur in November 2004. Since then, it has been celebrating “Pengba Day” every year in Manipur. It is a seasonal and riverine spawner that spawns only in river during June and July. This fish species was listed among the 91 endangered fish species of India according to IUCN status and categorized as extinct in the wild (CAMP, 1997).But now some competent fish farmers start culturing this fish and can produce in a minimal quantity.

Its global IUCN species status is “endangered (EN)” according to the “B1ab (iii, v)” criterion. There are not enough reliable sources containing data on this species, particularly in the recent period. As primarily a groundwater fish, it was exceptionally well adapted to environmental conditions in the Buško Blato reservoir. Based on the recent findings, the status of this species has changed over the past several years. The main objective of this study was to characterise and determine the current status of the monotype species A. huegelii from the Buško Blato reservoir, through the analysis of its selected morphological and ecological features. During field research, we have gathered 88 individuals of A.
