Collapse of the socialist system caused decline in fish farming production, mainly because of cease of fish rearing in heated waters of electric power stations. During postsocialist period all the remaining fish farms have been privatised. The trout farmers are now using only formulated dry feeds, while the carp farmers applied lower stocking densities in order to make use of the natural food production of the ponds. The main trend has been rise of interest to the production of juveniles of commercially important native species (salmon, sea trout, brown trout, whitefish (Coregonus), pike, pike-perch, tench) for stocking into the natural waters. The fish farmers hoped that government, municipalities, owners of fishing rights and sport fishermen would be interested in financing the production of stocking material. Demand on the carp fingerlings by the owners of small water bodies (farm and garden ponds, small lakes etc.) has increased too.
Australia's largest predator until about 3500 years ago. • The thylacine resembled a large, short-haired dog with a stiff tail which smoothly extended from the body in a way similar to that of a kangaroo. • Its yellow-brown coat featured 13 to 21 distinctive dark stripes across its back, rump and the base of its tail, which earned the animal the nickname “tiger". • Its body hair was dense and soft, up to 15 mm (0.6 in) in length; in juveniles the tip of the tail had a crest. Extinction in Australia • The thylacine is likely to have become near- extinct in mainland Australia about 2,000 years ago, and possibly earlier in New Guinea. • The absolute extinction is attributed to competition from indigenous humans and invasive dingoes. • Humans had an adverse effect on the environment and brought disease to Australia that their arrival drove the thylacine to extinction.

determining different characteristics obtainable from the skeletal material. The condition of the skeletons is not good, because of sandy soil, unfavourable for preserving human remains. Still attempts were made to determine the age and sex of the buried, additional attention was paid to possible pathological finds. The age of the buried was determined by studying the attrition of teeth (adults), and the development of teeth and the length of long bones (children and juveniles). Sex was determined only on the remains of adults. Sex was determined by metric (measurable characteristics for sex determining) and non-metric methods. The results (see TABLE 7) show a rather typical Southern-Estonian village cemetery (the comparison given from a number of similar cemeteries from the period). There seems to be a bigger ration of females buried and juveniles. The author of the present study can not explain that.

experimentally. In the open sea, the rapid dilution of naturally dispersed oil and its soluble components, as well as the high natural mortality and patchy, irregular distribution of plankton, make significant effects unlikely. In coastal areas some marine mammals and reptiles, such as turtles, may be particularly vulnerable to adverse effects from oil contamination because of their need to surface to breathe and to leave the water to breed. Adult fish living in nearshore waters and juveniles in shallow water nursery grounds may be at greater risk to exposure from dispersed or dissolved oil. The risk of surface oil slicks affecting the sea bed in offshore waters is minimal. However, restrictions on the use of dispersants may be necessary near spawning grounds or in some sheltered, nearshore waters where the dilution capacity is poor. The impact of oil on shorelines may be particularly great where large areas of rocks, sand and mud are uncovered at low tide
flounders and the fishes serve as a definitive, intermediate or paratenic host Trematodes Cryptocotyle concava was the most abundant parasite, although less numerous in spring. Its definitive host is a fish eating bird and flounder serves as intermediate host. Two species of Corynosoma (Acanthocephala) were found in the prevalence of 42 % both in autumn and in spring. Flounder and various fish act as paratenic host, transferring the parasite juveniles to their definitive host, the seal. 38 Nematodes Dichelyne (Cucullanellus) minutus and Cucullanus heterochrous are only found in flatfishes. Their occurrence in flounder reflects a long history of co-occurrence. D. minutus is generally found in smaller, younger flounders who populate the shallow costal waters. C. heterochrous on the other hand is found in older specimen who take part in the spawning migrations to the high sea. C

Ya no temía a mi propia muerte ni a la no existencia. Me daba menos miedo la posibilidad de perder a otros, aun sabiendo que desde luego los echaría de menos. ¡Qué poderoso es el miedo a la muerte! Llegamos a grandes extremos para evitarlo: crisis de madurez, aventuras amorosas con personas más jóvenes, cirugías estéticas, obsesiones con la gimnasia, acumulación de bienes materiales, procreación de hijos que lleven nuestro nombre, esforzados intentos de ser cada vez más juveniles, etcétera. Nos preocupa horriblemente nuestra propia muerte; tanto que, a veces, olvidamos el verdadero propósito de la vida. Además estaba empezando a ser menos obsesivo. No necesitaba dominarme sin cesar. Aunque trataba de mostrarme menos serio, esa transformación me resultaba difícil. Aún tenía mucho que aprender. De hecho, ahora tenía la mente abierta a la posibilidad (incluso a la probabilidad) de que las manifestaciones de Catherine fueran reales. Esos datos increíbles sobre mi
