Meat Yield and Shell Dimension of Smooth Scallop (Flexopecten glaber) Caught from Çardak Lagoon in Canakkale, Turkey
In this research, meat yield and shell dimension of smooth scallop (Flexopecten glaber) were specified. 150 individuals of smooth scallop were caught by dredges seasonally in Cardak lagoon on Canakkale strait, Turkey. According to results, the relationship of total shell length between total shell weight was determined as TW = 0.5207* TL 2.4533 (R2= 0.73). Moreover, meat yield of scallop was determined highest as whole meat in spring and as adductor muscle in summer. This paper reveals basic growth data of smooth scallop and its preliminary study for Cardak lagoon which is important bivalve inhabiting area.
Allometric relationship and meat yield of Chama pacifica broderip, 1835 from the Gulf of Antalya, Turkey
In this study, the allometric relationship and the meat yield of the large Pacific jewel-box Chama pacifica Broderip, 1835 were investigated. C. pacifica samples were by scuba diving at depths of 3-8 m in the Gulf of Antalya. The relationship of total shell length and total shell weight was determined as TW = 2.2693*TSL 2.5327 (R 2 = 0.69). The mean flesh weight and mean meat yield were determined to be 11,07±0.445 g and 6.84±0.18%, respectively. This research revealed the meat yield data of C. pacifica and its potential importance as a food source. Keywords: Chama pacifica; Pacific jewel-box; flesh weight; meat yield; allometric relationship
Gametogenic cycle and biochemical composition of the transplanted carpet shell clam Tapes decussatus, Linnaeus 1758 in Sufa (Homa) Lagoon, Izmir, Turkey
Knowledge of the gametogenic cycle and biochemical composition of commercially valuable species is important in aquaculture. Monthly variations in meat yield, gonadal development and biochemical composition of the bivalve Tapes decussatus were studied from January 2002 to December 2002 in the Sufa Lagoon in relation to environmental conditions. Histological evidence showed that gametogenesis began in January and major spawning started in July and appeared to continue into August and September. The majority of individuals were resorbing their gonad, or alternatively in a period of gonadal inactivity in October, November and December. When the gonad stage was ripe in April, the glycogen value was at the maximum level in contrast to protein which was at the minimum value. The glycogen value was at the minimal level during spawning and resting period. During the late gametogenesis the protein value was the highest in March and the following month when the gonad was ripe, protein was at the lowest. Lipid content fluctuated throughout the study. During the gametogenesis, the meat yield was observed to range between 12.7% and 26.8%. The results of this study showed that six stages of gonadal development of T. decussatus were observed in transplanted area. Seawater temperature was the major factor rather than food availability on gametogenesis of carpet shell clam in the study area.
