In order to clarify the distribution pattern of Cobitis populations along the southern Caspian Sea basin, 97 specimens collected from five localities were morphologically examined.
Kako bi se razjasnila raspodjela populacije vrste Cobitis u južnom dijelu Kaspijskog jezera, morfološki je ispitano 97 jedinki te vrste, prikupljenih s pet različitih lokaliteta.
Univariate analysis of variance showed significant differences (P &lt; 0.05) among the means of the five groups for 28 of 33 standardized morphometric measurements and 7 of 10 meristic counts.

In the linear discriminant function analysis (DFA) for morphometric characteristics, the overall assignment of individuals into their original groups was high (84.9%), indicating that these populations are highly divergent.
Prilikom linearne diskriminantne funkcijske analize (DFA) prema morfometrijskim karakteristikama, ukupna podjela jedinki u njihove izvorne skupine bila je visoka (84,9%), što ukazuje na to da se te populacije znatno razlikuju.
Clustering based on Euclidean distances among these groups of centroids using UPGMA and principal components analysis (PCA) indicated that the southeastern Caspian spined loach populations are C. faridpaki and the south central ones are C. keyvani and an unknown population, Cobitis sp. is distinguished from the southwestern populations of the basin.
Grupiranjem na temelju euklidskih udaljenosti između ovih pet skupina centroida, koristeći rezultate UPGMA i analize glavnih sastavnica (PCA), utvrđeno je da C. faridpaki spadaju u jugoistočne kaspijske populacije vijuna, da C. keyvani spadaju u centralni južni dio jezera te da se nepoznata populacija, Cobitis sp., razlikuje od jugozapadnih populacija sliva Kaspijskog jezera.
Also the Tonekabon and Sefidroud Rivers were determined to be the two new habitats for C. keyvani in the region.
Rijeke Tonekabon i Sefidroud su dva nova staništa za vrstu C. keyvani u regiji.

Blackspotted Croaker (Protonibea diacanthus) is one of the most commercially important croakers which migrate along West Bengal coast during winter season.
Protonibea diacanthus jedna je od gospodarski najvažnijih vrsta ribe na obali zapadnog Bengala u posljednjih nekoliko godina.
This paper deals with the importance of the species along with its market value and the cause of its popularity in West Bengal.
Provedeno istraživanje u ovom radu bavi seispitivanjem tržišta i uzrocima popularnosti ove vrste u zapadnom Bengalu.
This species is gaining prime importance among the fishermen due to the highmarket price of its swim bladder.
Ova riba jako je važna za ribare zbog visoke tržišne cijene njezinog plivaćeg mjehura.
In spite of this risk, a shift from pelagic to demersal fishing across the northern Bay of Bengal marks an important emerging trend of winter fishing in this area.
Unatoč riziku, postoji pomak od pelagičkog ka pridnenom ribolovu na sjeveru Bengalskog zaljeva, što pridonosi razvitku trenda zimskog ribolova u tim krajevima.

Noah's ark shell Arca noae Linnaeus, 1758 is one of the most important commercially exploited bivalve species in the eastern Adriatic Sea.
Kunjka Arca noae Linnaeus, 1758 jedna je od najvažnijih komercijalno iskorištavanih vrsta školjkaša na istočnoj obali Jadrana.
High harvesting pressure, as a consequence of increasing market demands, could in the future result in its overexploitation in some areas.
Visoki intenzitet ribolova, kao posljedica rastuće potražnje na tržištu, u budućnosti bi mogao dovesti do pretjerane eksploatacije prirodnih populacija u pojedinim područjima.
All mentioned above, together with a high market price, make A. noae a new species for introduction into aquaculture.
Kada se navedenim činjenicama pridoda i visoka cijena na tržištu, kunjka A. noae se nameće kao moguća nova vrsta u akvakulturu.
The aim of this paper was to give a review of present knowledge on A. noae, particularly biological characteristics of this species related to aquaculture production.

ZONING OF COASTAL AREA FOR MARINE AQUACULTURE Š PRESENT SITUATIONS AND PROBLEMS Bavčević, L., Vodopija, T., Lovrinov, M.Keywords:
ZONIRANJE OBALNOG POJASA ZA MARIKULTURU - STANJE Bavčević, L., Vodopija, T., Lovrinov, M.Ključne riječi:
Under these condition, marine aquaculture is frequent subject of many discussion focused on the environmental impact.
Postavljena u okvire sukoba interesa raznih djelatnosti za obalnu crtu, marikultura traži svoje mjesto.
Conflict of different interest in coastal area with no argumentation is putting marine aquaculture in worst position related with tourism and industry.
Jačanjem intenziteta djelatnosti u obalnom pojasu marikultura je sve više predmet raznih ciljanih rasprava, ponajviše s pozicija njezina utjecaja na okoliš.
Hard argumentations is laying in noneadequate frame of work in some facilities and to take advantake competitors are preasenting marine aquaculture in worst picture.
Sukob interesa u obalnom pojasu neargumentirano postavlja marikulturu u nepovoljni položaj s obzirom na turizam i industriju.
Marine aquaculture product has to be health product, which can be completely damaged because of non-responsible approach of other activity.
Snaga argumenata leži samo u nepravilnom gospodarenju na pojedinim farmama i, radi ostvarivanja prednosti, cijelu djelatnost prikazuje u najgorem mogućem kontekstu.
Fecal pollution from towns, pollution from bad controlled tourists activity, industry, influence of intensive and non controlled agriculture in coast line, are also potential danger for quality of all sea products and also cultured products from marine aquaculture.
Onečišćenja prouzročena otpadnim vodama gradova, nekontroliranom turističkom aktivnošću, industrijom, pod utjecajem intenzivnog i nekontroliranog poljodjelstva u obalnom pojasu, moguća su opasnost za kvalitetu svih morskih proizvoda pa tako i proizvoda iz marikulture.
High quality of marine products can be obtained by zoning of coastal area, and in concept of these zoning it is necessary to define the zones for marineaquaculture.
Najbolji način za očuvanje visoke kvalitete morskih proizvoda može se riješiti zoniranjem obalnog pojasa i u kontekstu tog zoniranja treba odrediti zone za marikulturu.
Procedure of zoning has to be divided in three steps: deetrmination of present status of area, definition of shore land for making mariculture related shore infrastructure and definitions of areas suitable for mariculture with limits of production.
Definiranje zone s aspekta kvalitete akvatorija određujući nulto stanje, definicija pristupa obali radi postavljanja obalne infrastrukture i određivanje takvih akvatorija prostornim planovima može dovesti do izbjegavanja konflikta u iskorištavanju istih resursa u budućnosti.
Living resources quality in zones for marine aquaculture must be control and protected from pollutant of others activities, by controlling of polluted water in zone, controlling of emission in land in zone (pesticides and fertilizers), and sanitary control of sea.
Postavljeno u kontekstu zaštite obnovljivih resursa u zonama marikulture potrebno je u okvirima ovlaštenih tijela provoditi praćenje štetnih utjecaja drugih djelatnosti na žive organizme u zoni za marikulturu, kontrolom otpadnih voda u zoni, kontrolom emisije u tlo u zoni (pesticidi i gnojiva), sanitarnom kontrolom mora.

A significantly large landing of Blacktip Sea Catfish (Plicofollis dussumieri) was reported from Frasergunje Fishing Harbour of Sundarbans, West Bengal between 31 December 2011 and 6 January 2012.
Prijavljen je veliki ulov morskog soma (Plicofollis dussumieri) u ribarskoj luci Frasergunje, Sundarbans, Zapadni Bengal od 31. prosinca 2011. do 6. siječnja 2012.
Around 320 tonnes of Blacktip Sea Catfishes were caught during this period.
Oko 320 tona morskog pauka je ulovljeno tijekom ovog razdoblja.
Unusual heavy landings are frequent on Indian coast, but the present landing is bigger than any other published.
Iako su neobično veliki ulovi česti na obali Indije, navedeni ulov je veći od svih dosada objavljenih.
The important factors of aggregation of this fish species are the fog and temperature fluctuation during the winter season, though it is yet to be ascertained.
Magla i fluktuacija temperature tijekom zimskog razdoblja su važni čimbenici sakupljanja ove vrste što je potrebno potvrditi.
The growth of the Leuciscus illyricus is very good and better in relation to the upstream and downstream area of Cetina.
Rast ilirskog klena vro je dobar i bolji u odnosu na uzvodna i nizvodna područja Cetine.
The L. ukliva grows well.
Cetinska ukliva raste dobro.
The L. s. muticellus and A. Hugeli tend to spread in this area.
Primorska jelšovka i oštrulja imaju tendenciju širenja u ovom području.
The presence of the A. a. gibelio is harmful and can have a long-term negative effect on the ichthyofauna of this area, especially on endems.
Prisutnost je srebrnog karasa štetna i može imati dalekosežne negativne posljedice na ihtiofaunu ovog područja, osobito na endeme.
The lake is able to produce a greater ichthymass than it does now.
Jezero bi moglo producirati veću ihtiomasu od postojeće.

A comparative investigation on the effect of fowl fertilizer (4800 kg. ha-1) and mineral fertilizer NPK 17 : 8 : 9 (1.200 kg. ha-1) on the development of phytoplankton was carried out in two variations of an experimental fish farm of equal surface area of 0,1 ha-1 and depth 120 cm, during the culturing season from June to September, 1983.
Komparativna istraživanja o djelovanju kokošjeg gnoja (4.800 kg. ha-1) i mineralnog gnojiva NPK 17 : 8 : 9 (1.200 kg. ha-1 na razvoj fitoplanktona provedena su u dvije varijante pokusnih ribnjaka pojedinačne površine 0,1 ha-1 i dubine 120 cm u tijeku uzgojne sezone od lipnja do rujna 1983.
The production of carp fry reached about 1.000 kg ha-1 in both variations, without supplement feeding the fish.
Postignuta proizvodnja šaranskog mlađa iznosila je oko 1.000 kg. ha-1 u objema varijantama, bez prihrane riba dodatnom hranom.
In both variations of experimental fish ponds a similar phytoplankton community developed (QS=69%), which was composed of 151 species belonging to the systematic division of Cyanophyta (17), Euglenophyta (23), Pyrophyta (1), Chrysophyta (47) and Chlorophyta (61).
U obje varijante pokusnih ribnjaka razvila se slična fitoplanktonska zajedinca (QS=69%) koju je sastavljala 151 vrsta pripadnika sistematskih odjela Cyanophyta (17) Euglenophyta (23), Pyrrophyta (1), Chrysophyta (47) i Chlorophyta (61).
The cenotic structure of phytoplankton in fish ponds treated with the fowl fertilizer made up 131 species, and in the fish ponds treated with the mineral fertilizer 105 species.
