Sono ora disponibili i risultati preliminari del progetto di ricerca \"Sviluppo e utilizzo di attrezzi da pesca a trappola adattati alle condizioni della zona costiera polacca del Mar Baltico\". L'obiettivo principale della ricerca era quello di ridurre l'impatto della pesca sull'ambiente marino, evitando e riducendo, per quanto possibile, le catture indesiderate. Il progetto ha condotto una ricerca unica nel suo genere sull'uso di attrezzi da pesca alternativi: I vasi da pesca del Baltico.<\/span><\/p>\n

La ricerca \u00e8 stata condotta da un consorzio composto da un'organizzazione di produttori - Dar\u0142owska Group of Fish Producers and Shipowners e da un partner scientifico - West Pomeranian University of Technology di Stettino. Lo studio \u00e8 stato condotto sia sulla composizione per specie e lunghezza dei pesci presenti nel pescato, sia sull'efficacia della protezione del pescato dalle interferenze delle foche. Lo studio \u00e8 stato condotto da un team scientifico insieme a piccoli pescatori della zona costiera del Baltico polacco. La pesca di ricerca \u00e8 stata effettuata da 21 barche provenienti dal porto di Dar\u0142owo. I pescatori hanno effettuato crociere di ricerca tra luglio e la fine di novembre 2023. La pesca nell'ambito del progetto \u00e8 stata effettuata sulla base di un permesso di pesca di ricerca rilasciato dal Ministero polacco dell'Agricoltura e dello Sviluppo rurale. Nell'ambito dell'attuazione dell'operazione, sono state effettuate 30 crociere con ciascuno dei pescherecci. La crociera di ricerca consisteva nel pescare con reti da posta o ami passivi e con i vasi da pesca del Baltico testati. Durante la cattura, il pescatore ha collocato l'esca nella gabbia e l'ha lasciata a riposo per almeno 16 ore. Inoltre, sono state collocate una serie di reti da posta commerciali o fino a 1.000 ami. Durante la pesca, il pescatore ha registrato i dati relativi alle catture e ha debitamente compilato la scheda di cattura dell'indagine Baltic Fish Pots (comprendente il marchio del pescatore, il numero e l'ubicazione delle nasse da pesca calate, le caratteristiche dell'attrezzo di confronto - tipo di attrezzo, lunghezza della cala, distanza delle maglie, tempo di pesca, profondit\u00e0 della pesca, tipo di fondale, condizioni meteorologiche - stato del mare, forza e direzione del vento, temperatura dell'acqua, numero di pesci, specie di pesci catturati e loro peso all'interno della specie). Inoltre, sono state effettuate osservazioni e documentazioni subacquee delle nasse esposte. A ogni crociera, il pescatore ha consegnato in porto una scheda di cattura compilata per l'indagine sulle nasse da pesca baltiche e i pesci catturati dagli attrezzi da pesca (reti da posta o ami e nasse da pesca baltiche). Tutti i pesci catturati con le nasse e i merluzzi catturati con reti da posta o ami sono stati misurati (LT) e pesati (W).\u00a0<\/span><\/p>\n

La ricerca condotta ha permesso di trarre le seguenti conclusioni:<\/span><\/p>\n

    \n
  1. Tre specie ittiche hanno dominato la pesca in gabbia: il merluzzo (Gadus morhua<\/i>), passera di mare (Platichthys flesus<\/i>) e la gallina diavolo (Myoxocephalus scorpius<\/i>).<\/li>\n
  2. I pesci nelle nasse erano vivi e in buone condizioni.<\/span><\/li>\n
  3. Le singole catture di altre specie ittiche, come lo sgombro (<\/span>Scomber scombrus<\/span><\/i>), parr (<\/span>Alosa fallax<\/span><\/i>) e il pesce persico (<\/span>Perca fluviatilis<\/span><\/i>) sono stati osservati.<\/span><\/li>\n
  4. Occasionalmente \u00e8 stata osservata la presenza contemporanea di due specie ittiche nelle nasse: merluzzo e passera, merluzzo e gallinella.<\/li>\n
  5. Periodicamente una presenza significativa di meduse (<\/span>Aurelia aurita<\/span><\/i>) \u00e8 stato osservato nelle nasse per pesci, quando non \u00e8 stato rilevato alcun pesce.<\/span><\/li>\n
  6. Le foche grigie (<\/span>Halichoerus grypus<\/span><\/i>) sono stati osservati presenti e hanno mostrato grande interesse per la pesca di ricerca in corso. Durante la pesca sono stati osservati danni alle reti da posta e pesci intrappolati. Durante la pesca non sono stati osservati danni alle nasse da parte delle foche grigie, ma sono stati riscontrati due casi di foche rimaste impigliate nelle reti da posta. Si pu\u00f2 concludere che le nasse rispondono alle intenzioni originarie e sono resistenti alle foche e amiche delle foche.<\/span><\/li>\n
  7. Come risultato dello studio, \u00e8 stata identificata la necessit\u00e0 di condurre ulteriori ricerche, in altre aree della zona costiera del Baltico polacco e per un periodo di tempo pi\u00f9 lungo, tenendo conto delle modifiche previste al design della gabbia Baltic Fish Pots.<\/span><\/li>\n<\/ol>\n
