 Joyban,
 
 I  appreciate  what  you  say....
 
 Yes  we  can  tag  them!  but  with  what?
 
 Embedded  microchip  transmitters?  Well  arrawanas  have  them  but  they  are  huge  fish  when  compared  to  the  E.canarensis.  Will  the  fish  be  able  to  survive  with  one  of  these  embedded  in  it's  body?
 
 Do  we  have  the  kind  of  equipment,  resources  and  time?
 
 These  fish  after  our  trip  have  been  found  to  have  a  far  ranging  domain  than  they  were  previously  thought  to  have  had.  They  were  initially  reported  to  be  found  in  the  Kumaradhara  near  Uppinangady  and  nearby  places.  We  have  found  them  in  the  Netravathi  too  and  far  upstream  of  both  the  rivers  from  Uppinangady.  So  their  numbers  may  well  be  many  times  more  than  previously  estimated.
 
 Remember  they  are  cichlids  and  there  are  no  other  cichlids  in  these  waters  upstream  where  we  looked.
 
 We  simply  cannot  ask  for  a  ban  without  sufficient  data.  There  are  quiet  a  few  people  whose  livelihood  depend  on  these  fish.  Let's  be  responsible  and  balanced  conservationists,  unlike  some  of  the  groups  who  create  a  ruckus  simply  to  secure  aid  to  squander  away  and  appear  on  TV.
 
 We  neeed  to  explore  other  river/stream  systems  connected  to  these  two  rivers  for  an  estimate  and  another  24  hour  trip  will  not  accomplish  that.
 
 Let's  explore  some  other  possibilities,  involve  Govt.  Organisations  to  this  end.
 
 The  best  thing  would  be  to  generate  an  interest  in  the  locals  to  set  up  breeding  areas  for  these  fish  aroung  the  places  we  visited  and  release  part  of  the  off  spring  back  into  the  wild,  and  selling  the  remaining  to  Aquarists.  This  should  stop  collection  of  this  fish  from  the  wild  in  theory.
 
 Practically,  the  Fisheries  Officials  themselves  will  ban  and  then  sell  this  fish  at  an  exorbitant  rate  like  they  did  with  the  African  Red  tailed  catfish  in  Karnataka  last  year.

 Ravi,  very  nicely  done    Very Happy  
 
 The  "half  beak"  on  page  six  looks  like  a  Xenentodon  cancila,  the  Indian  needlefish...need  a  better  pic  for  a  positive  ID  though.
 
 If  it  took  all  that  effort  to  get  a  couple  of  fish,  how  did  you  guys  end  up  with  ~40??

 Hi  Rahul,
 
 This  is  only  part  of  the  story.  There  were  other  guys  fishing  else  where.  Also,  Beta,  Adip  &  Co  went  fishing  on  Sunday  morning,  long  before  rest  of  us  got  up.  Those  pictures  are  not  here.

 Rahul,  on  the  first  day,  the  photographers  were  all  too  excited  and  busy  shooting  the  ratfish  in  the  pool  and  left  the  netmen  all  to  themselves.  They  collected  more  than  a  dozen  in  the  first  location  after  letting  slip  many  more.
 
 In  the  2nd  location  we  netted  a  single  Eli  Meenu,  there  were  too  many  hiding  places  for  them  and  with  the  water  shin  deep  the  cast  net  was  no  help  so  was  the  seine.
 
 There's  another  article  that  beta  is  yet  to  put  up,  a  bit  of  night  fishing  netted  us  a  few  more.
 
 It  was  bloody  difficult  to  net  these  fellers.  More  over  responsible  aquarists  that  we  are  :wink:  ,  we  only  wanted  to  bring  back  about  20  or  so  that  the  guys  had  tanks  ready  for.
 
 But  was  it  fun!

 I'll  quote  Vinny  Kutty  on  the  gender  bit  -  "  Distinguishing  the  sexes  is  challenging  with  E.canarensis  but  in  adult  females,  there  is  a  hint  of  whitish  smear  at  the  upper  and  lower  distal  margins  of  the  tail."
 
 The  above  quote  is  taken  from  Vinny's  Article  "  In  search  of  the  Etroplus  canarensis"  published  in  the  Buntebarsche  Bulletin  227.
 
 My  thanks  to  Rahul  for  the  article.
 
 Ravindran's  leg?
 
 We'll  let  radyworks  update  on  that.

 Hi  all  wanted  to  update  this  site  with  the  story  of  EC  rediscovery  by  Andrew  the  following  was  posted  in  the  http://www.petfrd.com  forum.  
 
 
                                                 
Quote:                

 Originally  Posted  by  cloud79  at  petfrd.com  forum
 Andrew,  you  are  the  collectors  of  these  wonderful  fishes  rite?  I  remember  that  i  have  read  somewhere  that  this  fish  is  supposed  to  be  extinct  and  then  they  are  been  discovered  yet  again.  Mind  telling  us  the  story  behind  it  since  you  are  the  man  behind  on  collecting  carenesis.  
 
 
 Origibally  Posted  by  channaamphibius  at  petfrd.com  forum
 I  am  not  aware  of  the  'extinct'  part,  but  there  was  NO  INTEREST  shown  by  qualified  Indian  Icthyologists  to  rediscover  or  report  this  fish's  whereabouts  subsequent  to  it's  initial  discovery.
 
 In  1996,  Rohan  Pethyagoda  of  the  Wildlife  Heritage  Trust  of  Sri  Lanka  arrived  in  Kolkata  to  to  do  a  photo  shoot  on  Hamilton's  described  fish  of  the  River  Ganges.  I  assisted  him  by  procuring  specimens.
 
 He  then  very  kindly  invited  me  to  join  him  and  his  team  for  a  survey  on  some  of  the  type  areas  of  fish  described  by  Francis  Day.  In  April  of  the  same  year  saw  us  starting  our  month  and  a  half  long  survey  from  Thiruvananthapuram  in  Kerala  right  up  to  Mangalore  in  South  Karnataka  .  
 
 On  approching  the  crossroads  in  South  Canara  approx  50  Km  from  Mangalore  near  Bantwal  we  contemplated  to  fish  in  the  Netravati  river  closer  to  Mangalore  a  sea  port  or  further  upstream.  This  undecidedness  was  driven  by  the  fact  as  the  the  other  two  Etroplus  species  found  in  India  :  maculatus  and  suratensis  are  found  in  brackish  waters  too  and  the  river  closer  to  Mangalore  would  be  more  saline.  After  giving  the  matter  some  thought  we  decided  to  fish  in  pure  freshwaters  and  we  traversed  the  Netravati  further  upstream  to  a  small  town  called  Uppinagadi.
 
 Our  first  forays  at  the  river  yielded  a  few  juveline  suratensis  and  habitat  was  very  rocky  and  fishing  by  seine  too  difficult.  We  used  a  cast  net  too  and  eventually  netted  first  one  and  then  two  juveline  3  -  4  cm  E.  canarensis  before  calling  it  a  day.
 
 April  of  1999,  saw  me  again  at  the  same  spot  with  an  associate  who  lives  nearby  and  we  netted  a  single  specimen.  I  found  as  compared  to  the  earlier  time  three  years  ago  the  water  levels  were  much  higher.  But  this  time,  the  levels  were  pretty  low  and  at  places  clear  enough  to  see  the  fish.  We  saw  quite  a  few  of  the  fish  mainly  small  ones  darting  from  place  to  place  but  catching  the  same  proved  too  difficult.
 
 Later  that  year  that  associate  of  mine  from  the  trade  commenced  collections  of  the  fish  and  the  efforts  on  a  few  times  yielded  a  few  dozen  specimens  which  subsequently  reached  aquarists  worldwide.
 
 I  was  at  the  same  area  again  in  October  last  but  the  water  levels  was  above  the  danger  levels.  Last  year  there  was  abnormally  high  rainfall  in  Karnataka  and  the  South  as  a  whole  and  floods  were  rampant  in  most  areas.  I  did  not  fish  and  could  not  too  beacuse  of  the  very  high  water  levels  but  did  some  Goby  collections  much  further  upstream  at  Bantwal.
