FISH PAINTINGS OF THE TIIIRD MILLENNIUM B. C. FROM NAL (BALUCHISTAN) AND THEIR ZOOGEOGRAPHICAL SIGNIFICANCE By SUNDER LAL HORA, Director, Zoological Survey of India, Indian Museum, Oalcutta. (Plates IV-VI.) INTRODUCTION. Antiquity of N al.-In the note appended Shri A. Ghosh, Director-General of Archaeology in India, has very kindly given a description of the archaeological site at Nal, with a brief history of its discovery and subsequent excavations. He has also described the various types of pottery known to be of a funerary character through their association with burials. The distribution of the N 801 type of pottery is lilnited, being confined to two other places, Nundara. in Ba.luchistan and Damb Buthi in Sind. After discussing the culture represented by these three sites, Shri Ghosh is of the opinion that "The priority of N aI, by virtue of its association with Amrl, to Harappa may be a reasonable guess at the same time, ifit survived Amri the possibility of its having witnessed the rise of Harappa and having been, to a certain Iii LAND ABOVE 4000 Feet. ~==;~=-=-~-=-=-========2 ~ TEXT-FIG. l.-Settlement sites of the Indus Valley Civilization.

Golden Mahseer, Tor Putitora (Hamilton, 1822)
Golden mahseer, Tor putitora (Hamilton, 1822) Name of contributor: Dr. D. Sarma, Dr. M. S. Akhtar, Dr. S.G.S.Zaidi and Mr. Rajesh M ICAR- Directorate of Coldwater Fisheries Research, Bhimtal -263136, Nainital, (Uttarakhand) India E Mail: [email protected] Golden mahseer (Tor putitora), is an important cyprinid which is considered as a flagship species in upland fisheries of Himalayan sub-continent by virtue of its economic, ecological, recreational, heritage, cultural and food values. However, the population of golden mahseer has been greatly dwindling over the years and as a result, it has been declared as ‘endangered’ by IUCN. It is a multiple spawner; spawning season coincides with the onset of rains during May to September with two peaks (May-June & August-September). Males mature at the age of 3+ years while females mature at 5+ years. Mature males are in oozing condition throughout the year whereas ripen females have swollen belly with lemon yellow/brownish-golden colour eggs of diameter 2.0 – 2.5 mm. The flow through hatchery technology for captive breeding and nursery rearing of golden mahseer developed at ICAR-DCFR is the first of its kind in the country and consistently producing golden mahseer seeds. For captive breeding, the brood stock of 800-1500 g can be raised at temperature range of 18-220C in concrete tanks/ FRP tanks @ 2-3 no/m2. Photothermal manipulations coupled with the provision of spawning substratum using bed bio-filter installed in FRP tanks and quality feed (44% protein), with regular health checks helps to achieve multiple spawning in captivity. -
The Introduced Fishes of Nevada, with a History of Their Introduction
TtlE INTIl()I)I'(!ED FISltES ()F NEVAI)A, WITII A IIISTORY ()F TltEIR INTRODUCTION I{OB1,;RTR. 51mne•d Museum o[ Zoology, University o[ Michigan A•,• Arbor, Michiga• AND J. R. A•cou• Departme•t o.f the Interior, Fish a•d Wildlife Service Fallon, Nevada .•BSTRACT At least 39 spccies and subspecies of fishes ht;vc beta introduced into the waters of Nevada since 1873. Of these, 24 kinds arc now known to occur in the state. A thorough survey of the exotic fishes has not been nmde, but specimens or records of introduced species have been kept in the course of rather extensive collectlug of the native fish famm from 1934 te 1943. Con- sequently it is believed that the number of introduced species herein eaumer- ated approaches a complete tabulation. Some additions among the sunfishes and eatfishes may be expected. The annotated list is divided into tWO parts: species now present in the state, and species introduced but never established. The established kinds constitute about two-thirds of the total number of known native species, but are far outnumbered by the indigenous fishes when all the local subspecies (I-Iubbs a•d Miller, in press) are included. The stocking of cutthroat trout and rainbow trout in the stone creek should be discouraged since these two species hybridize extensively and the cntthroa• trout are speedi'ly eliminated. Brook trout and cutthroat trout, however, do not hybridize. A suggested practice would be to select separate streams when planting rainbow and cutthroat species, a procedure greatly simplified by the presence of many isolated creeks throughout the state. -

Short Communication A comparison of the survival and growth performance in rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) fry 1 2 2 1 1 Volkan Kizak *, Yusuf Guner , Murat Turel , Erkan Can and Murathan Kayim 1 Tunceli University, Fisheries Faculty, Tunceli, Turkey. 2 Ege University, Fisheries Faculty, Izmir, Turkey. Accepted 21 May, 2018 The rainbow trout is an intensively cultured species because of its more cultivatable character than the brown trout. In this experiment, the brown trout culture did not expand due to low growth performance compared to that of the rainbow trout. This experiment was conducted in a commercial trout farm, Aegean Area (Turkey). Growth performances and survivals of rainbow and brown trouts from fry to fingerling were observed for 155 days. Growth performances, feed conversion rates and survivals were determined. The initial weights of the rainbow and brown trouts were 0.1 ± 0.01 g. Final weights were 26.5 ± 5.19 g and 12.97 ± 2.74 g, respectively at the end of experiment. Survival and FCR of rainbow and brown trouts were 83.9 and 80% ; 0.59 and 0.61 respectively. As a result, there is a similarity between these two trout species in point of survivals and FCR’s although growth performance of the rainbow trout was significantly better than that of the brown trout. -

Nistor1*, I.B. Pagu1, E. Măgdici1, G.V. Hoha1, S. Paşca1, B. Păsărin1 1University of Agricultural Sciences and Veterinary Medicine Iasi, Romania Abstract Research was carried out on three trout breeds, rainbow trout (Oncorhynkus mykiss), brown trout (Salmo trutta fario) and brook trout (Salvelinus fontinalis), which are the most farmed salmonid species in N-E part of Romania. To assess the meat quality of rainbow, brown and brook trout we considered that it’s necessary to make some histological investigations about muscle fibre diameter. The research was done using fish of two years old. Muscle was systematically sampled and differentiated by breed and body mass and the results were statistically analyzed and interpreted. The comparative statistical analysis revealed significant differences between the three trout breeds. After the histological examination of rainbow, brown and brook trout muscles the conclusion that emerges is whatever of breed, the muscle fibre structure and fineness has a significant trend according to the dynamics of growth.

Approach: The structure of the populations in the six rivers of the southern part of Caspian basin including: Keliyare, Khojirood, Lar, Shirinrood, Rig cheshme and Pajimiyane, were studied. Results: Five age classes, ranged from 0 +-4+ years, were determined. The most frequent age classes belong to 1 + and 2 +. The length ranged from 78-305 mm and weight ranged from 3.6-390 g. Also, the condition factor ranged from 0.58-1.47. The highest and lowest length, weight and condition factor were observed in Lar and Rig cheshme, respectively. In 5 out of 6 rivers, females were dominant over males. The highest and lowest female: Male ratios were observed in Pajimiane (6.75:1) and Khojirood (0.8:1), respectively. Significant relationships were found between total length of brown trout with depth (r = 0.6, p<0.0001) and width (r = 0.68, p<0.0001) of habitats in these studied areas. -

No Stocking Filler
10 No Stocking Filler Steve Lockett Introduction Let us be in no doubt, rivers are under huge and growing threat (¹) despite the apparent clean-ups seen under the recent virus pandemic lockdown measures. Yet the reliance on clean water for health and the focus on how rural communities rely upon rivers for food and building materials has done little to move public debate away from the development versus conservation agenda ‘struggle’. My interest is in Mahseer, large fish of genus Tor, members of the cyprinid or carp family. Endemic to most rivers of India, and ideal candidates as umbrella species and indicators of ecosystem health due to their role as predators, their need for highly oxygenated water flows and migratory habits for spawning purposes. For those who don’t know about them, they can be large, with mature individuals of at least two Indian species capable of growing to over 45 kg, they have been subject to many fables throughout written history, with records of exploits of those trying to catch them dating back to King Someshwara III in the Chalukya dynasty and paintings of them appearing on pottery from the Harappan civilisation. Given the absence of bones of Mahseer in midden pits of Harappan cities, although there are bones of almost every other fish species and evidence of equipment capable of catching powerful fish, it has long been concluded that these fish are the original sacred animal that should not be eaten. The links between Mahseer and matsya, an incarnation of Vishnu, adds to this legend. Under pressure While rivers are exploited mercilessly for water, power and minerals, with the associated threats to ecosystem stability, fish tend to go about their lives unseen. -

PANDEY Directorate Of Fisheries, 7-Faizabad Road, Lucluww- 226 007. ABSTRACT The present status of the. Himalayan m.ahseer in the three lab:es of Nainital district of U.P. is discussed based on the catch data from 1983- 84 to 1992-93. Yield of mahseer have shown a gradual decline in the recent years. Besides catch statistics, marlret arrivals and availability of fish to anglers have also shown a marked decline. Tor putitora is being considered as an endangered fish. It is therefore necessary to repopulate the lake9 with the mahseer by adopting better Inanagement practices like stocking the lakes continually with sufficient mahseer fingerlings and enforce stdct conservation measures to stop killing of juveniles. The mahseer Tor putitora. a very better management and national important food and game fish of the exploitation of the lakes have been Himal::1yan region, is suffering a severe discussed in this paper. Himalayan set back in the upland natural water mahseer which is being considered as bodies because of dynamiting and illegal an endangered fish, can certainly be fishing.
