LAND AND WATER
(By "DalbiaO The cry about poor fishing or floor fish it being echoed all over the country. Canterbury anglers complain that although thoro are plenty o' fish of small size a big fish is a rarity. A great number of fair-sized trout were liberated in tho Avou before the season opened, but they are reported to bo scarcer than ever before in the terrace reaches of tho river. Tho question of tho rights of laudowners over tho fishing in their rivers will have to bo faced by societies sooner or later. Of course the legal aspect of tlie matter requires no further settlement. Tho only question is how far tho societies will have to go in order to secure for their license-holders a" duo measure of freedom over the best .fishing streams. The "Observer” states that as a protest against what they consider to bo tho improper extension of legal rights to the Wellington Acclimatisation Society many propertyholders in tho Wairarapa intend to decline permission to anyone holding a license from the society to go upon their land to fish. If tho owners have not the right to give a visiting friend leave to fish in their own creeks, tney are not going to grant such privilege to the friends (at a pound a head) of tho Acclimatisation Society. If the owners adhere to their resolution, licenses will be almost worthless. -

He says:—"The his- , lory oi the cusp wasthatouc of one lot of some two Hundred salmon over seventy Had died witnm the past eight mouths, '.those salmon were specimens ot tiio "Saline salar,” were three years of age, and were hatched from ova imported from Great tin tain.

After several deaths had taken' place they were removed to a round pond of good size and a maximum depth of about 6ft, the aeration of which was not by any means so good. Here the mortality continued, and after two weeks in this pond they were removed to a well aerated race which had a perforated wooden division in the middle, the apparently healthy fish being placed in one end and the diseased in the other. The diet of these fish had always been sheep’s liver obtained in a fresh condition front the Dunedin Abattoir, excepting for one short space of time when they were fed on maggots. They have never been in suit water except for a few salt baths, when they were only immersed a few minutes each. A large piece of rock-salt had been placed in the race, but this was not sufficient to affect the water materially, and as there was a rapid influent and effluent the effect was further minimised. On examination of the healthy fish I found these to ho, ns is only to be expected of salmon in confinement and cbnstant fresh water, of inferior development, being far smaller for tbeir age f!mn is the case with salmon under natural conditions. I also noticed an unusual number of deformities among these fish, and I am of opinion these and possibly to some extent the arrest of general development may be due to weakness of the ova from which these fishes were hatched. On examination of the diseased fish which were in segregation I found that the symptoms pointed to excessive weakness, and inability to maintain a normal equdibriura in the water. Some of them through lying on the side or belly at the bottom of the The children in more than one hundred families in the Carterton district have been attacked by measles and influenza.

All these fish were quite free from maggots in the gills, or any externa! parasites. The report goes on" to describe the exhibited bv the diseased fish, and continues:—As a result of the investigation T am very much inclined to believe that the ova

Tho annual angling competition (with bare fiy only) lor medals presented by tho Olugo Acclimatisation Society took place on tho U’aipatu river on tho Bth inst. Tho gold medal was won by D.

Trout havo been caught this 3*car for the first time in a small lake Waiotapu, whoro fine fish recently succumbed to a sportsman's hour. An angler recently took seven fish, totalling 40lb. from tho Okoro river, off Lake Kotoiti.

It was seen to bo weak and sickly, and on being captured was found tone infested with' ticks, which established themselves on its neck whoro tho bird was unable to hurt them. Air T. \V. Kirk (Government Biologist) and Mr A. lv. Young (Into of tho Veterinary Bivision), who was in South Africa with ono of the New Zealand rogime*nts, both examined the ticks and were convinced that they were not the African tick. They are closely allied to the species which prey? on penI - gains, kiwis, and many native birds. It would be interesting to know to what extent the tick is prevalent among wild ducks and whether it is causing serious mortality.
