Variations in length-weight relationship, growth and body condition of the commercial mullet Ellochelon vaigiensis in the Vietnamese Mekong Delta

The reproductive biology of Ellochelon vaigiensis from the Vietnamese Mekong Delta

“…The overall sex ratio in this study was 1.26 males:1.00 females. More males may be indicative of fishing activities targeting larger individuals (such as females) (Dinh, Truong, Nguyen, Tran, et al., 2022 ), and females tend to accumulate more fat than males. At Tran De, Soc Trang and Dong Hai, Bac Lieu, the sex ratios were approximately 1:1, different from the other two study sites.…”

“…Some studies on E. vaigiensis in the Mekong Delta have been published. The growth pattern of E. vaigiensis is negative allometry because the b value is <3 (2.13–2.68), and this fish is well adapted to the environment as the CF value approaches the well‐being threshold of 1 (0.97–1.13) (Dinh, Truong, Nguyen, Tran, et al., 2022 ). This squaretail mullet is an algi‐omnivorous with the food composition of mainly Bacillariophyta, followed by detritus (30.3%) and Cyanophyta (18.3%) (Dinh, Truong, Nguyen, Lam, et al., 2022 ).…”

First report on population dynamics and stock status of Badis badis in a wetland ecosystem (NW Bangladesh): Insights from new recorded maximum length

“…LWR is very crucial for the exploitation and sustainable management of the fish population and much essential for stabilizing the taxonomic characteristics of the fish species [ 57 ]. The database on LWR offers crucial insights into the growth patterns of fish [ [58] , [59] , [60] , [61] ] and fisheries management [ 58 , 62 ]. The slope parameter ( b ) in LWR is employed to determine the pattern of fish growth [ 38 , 58 ] and the condition factor (CF) is crucial for gaining information on ecological adaptation of fish [ 58 , [63] , [64] , [65] ].…”

In fisheries, LWRs prove extremely valuable for converting length distributions into weight measurements, facilitating biomass assessment [ 66 , 67 ].…”

Length-weight and length-length relationships of 16 marine fish species in Vietnam

“…In Vietnam, very few studies on the LWR and LLR of marine fish species have been documented. As far as we know, work has been done on Yellowfin (Thunnus albacares Bonnaterre, 1788) and Bigeye (Thunnus obesus Lowe, 1839) Tuna (Nguyen et al, 2022b), mudskipper (Periophthalmus variabilis Eggert, 1935 (Dinh et al, 2022a), mullet (Ellochelon vaigiensis Quoy and Gaimard, 1825) (Dinh et al, 2022b), and a few other fish species in the Gulf of Tonkin, northern Vietnam (Wang et al, 2011). In this context, this study aimed to provide information on the LWRs and LLRs of 16 marine fish species in Vietnam, to identify the growth type of each species and to contribute to understanding the biological and demographic information of these fish communities.…”
