Study the present trawl fishery of Penaeus monodon (Fabricius, 1798) in coastal waters off digha coast, West Bengal, India

Abstract

During the present study the average annual catch of Penaeus monodon during 2011 -2013 was 281.29±9.67 ton, which contributed 0.41 % to the total trawl net catches at Digha coast. The average catch rate was 43.41 kg/h. The percentage of P. monodon to total shrimp catch was 1.91% in trawl landings at Digha coast. Monthly mean landings were 28.13±0.97 t from the trawl nets. Peak landings were observed from June to November with a maximum of 56.46±1.97 t in September and lean landings were observed from December to March with a minimum of 6.12±0.21 t.

“…The length-weight relationship and condition factor in crustaceans have been welldocumented in different marine species worldwide (Wong et al, 2015;Uddin et al, 2016;Sousa et al, 2019). This relationship is an important tool in fisheries and aquaculture management as it provides information on growth patterns and on the general condition of the organism, reflecting fluctuations in the uptake and allocation of energy (Guino-o, 2012).…”

Freshwater Shrimp Diversity in Pidie Region, Aceh, Indonesia

“…shows that the growth pattern for shrimp (M. lanchesteri) in the Kunyet Lake, and for shrimp (M. lanchesteri, M. sintangesi, C. endhensis) in the Balu Cut River is negative allometric where length growth is faster than weight gain. The nature of this growth is the same as the growth pattern in the Ulu Ngarak River [26], in the waters of East Aceh [27], in Dolak [28], in the Strait of Hormoz, bay Persia [29], in the waters of Nagan Raya [15], and in India [30] which found that the growth pattern of male and female shrimp was allometric negative.…”

Length-weight Relationship and Condition Factors of Seven Penaeus Shrimp Species along the Southeast Coast of Tamil Nadu (Southern India)

“…The species-specific coefficient of determination Length-weight Relationship and Condition Factors of Seven Penaeus Shrimp Species along the Southeast Coast of Tamil Nadu.... female shrimp from the Barito River, Indonesia. One author from India also found that the negative allometric growth in both sexes of shrimp from the Digha coast of West Bengal has been studied by Uddin et al (2016). Some other authors similarly study reported by (Das et al, 2021;Ukpatu, 2021;Hasan et al, 2020;Suryanti et al, 2018;Khademzadeh and Haghi, 2017;Uddin et al 2016;Amani et al, 2015;Faye et al, 2015;Fatima, 2001;Fontaine and Neal, 1971).…”

“…Shrimp feeding intensity, age and growth rates may all be monitored using the condition factor, which is also beneficial. Both biotic and abiotic ecological circumstances heavily influence it and can be used as a gauge for the health of the aquatic habitat where fish reside (Prajapati and Ujjania, 2021;Solanki et al, 2020;Uddin et al, 2016). Fish and crustaceans' variations in the length-weight relationship are good predictors of energy absorption and allocation changes (Kop et al, 2019;Qadri et al, 2017).…”
