“…Similar results were reported in grow-out culture of P. monodon by Primavera et al (1998). However, allometric growth (b<3.0) was reported in pond reared P. monodon (Gopalakrishnan et al, 2014) and variation in growth from allometric to isometric (b value = 2.45 to 3.01) was reported for P. monodon cultured in different ecological conditions (Prasad, 2001). Hence the length-weight relationship is influenced by ecological conditions of the culture system and the recorded isometric growth of the present study indicates that the location of the cage culture site is suitable for culture of tiger shrimp in floating cages.…”

An experiment was designed and conducted to assess the feasibility for culture of Penaeus monodon in 6 m dia HDPE circular floating cage, installed at 10-12 m depth off Visakhapatnam in the Bay of Bengal. The cage was fixed with three cylindrical nets; inner net of 2 mm mesh (6 m dia×5.5 m height) to rear post-larvae from stock to 80 th day; middle net of 10 mm mesh (6 m×5.5 m) to rear juveniles from day 81 onwards and an outer net of 40 mm mesh (8 m dia×4.5 m height) to prevent entry of predators. Post-larvae (PL 23 ) of P. monodon (mean total length 16.1±3.8 mm), were stocked in the cage at a density of 1179 PL m -3 ). Bottom water parameters viz., salinity, temperature, dissolved oxygen, pH and ammonia (NH 3 -N) recorded in the cage site during the culture period were 34-35 ppt, 26-32°C, 3.9-4.6 ml l

“…The K value 1.31 for Macrobrachium sp. from this study were slightly higher than M. rosenbergii (1.09) under rice fields (Kunda et al, 2008), Atya gabonensis (1.014) from river (Okayi and Iyorkyaa, 2004) or P. monodon (0.727) under cultured (Gopalakrishnan et al, 2014). Meanwhile, the K values of 0.36-1.56 for fish are also commonly found in some fish species from other habitats.…”

The catching efficiency of light traps and morphometric characteristics of the native species from Barito river, Indonesia.Abstract: Various fishing gears are being used for harvesting fish and shrimp in Barito River, Indonesia. However, the use of lighted traps is still poorly studied. A set of fishing gears associated with light emitting diode (LED) and incandescent lamps was used as sampling tools. The trials consisted of 113-trap hauls/lamp type using 1-night submersion time of 15 h. The light traps were standardized to a catch per unit effort (CPUE). The light traps sampling accounted for 397 specimens assigned to 11 species of 7 families. There was highly significant difference in the number of catches between shrimp and fish (P<0.001). Shrimp sizes ranged of 24-85 mm total length and 0.3-10 g weight, while for fish 27-310 mm and 0.4-101 g. Yellow and red LED light traps seemed to be effective in catching Macrobrachium rosenbergii as well as white LED ones for Oxyeleotris marmorata. Both species solely showed positive allometric growth type (b = 3.42 and 3.28), while other species displayed negative allometric growth pattern (b = 0.82-2.71) with the condition factor (K) values ranged of 0.36-1.56. A new native species Macrobrachium sp. were found and considered as multichromatic species. The size and shape of the light traps did not affect number of catch. The mean CPUEs for incandescent and LED light traps were 0.07±0.06 and 0.13±0.20 fish net-1 night-1. No significant difference in the relative catching efficiency between both light trap types was observed.

“…On the other hand, if b ≠ 3 an allometric growth is presented by the species, suggesting a differential or disproportional growth of length and weight. When b < 3 the species shows a negative allometric growth (a preferential increase of length more than weight) and if b > 3, it indicates a positive allometric growth (a preferential increase of weight more than length) for the species (Gould, 1966;Gopalakrishnan et al, 2014).…”

Aspects of distribution and population dynamics were assessed in two rock shrimp species of the genus Sicyonia. Samples were obtained by sea bottom trawling in depths from 50 to 460 m during two research cruises on board the B/I BIP XII in the Gulf of California, Mexico. Taxonomic identification of specimens was performed; measurements of individual length and weight data were taken to obtain biometric relationships and length frequencies. Growth parameter estimations were performed adjusting the von Bertalanffy growth model (VBGM), and the recruitment pattern was obtained by the ELEFAN II method. Longevity was estimated with the Taylor equation, natural mortality with six different models, and length at first maturity by the logistic model. A total of 67 fishing trawls were monitored, and 1,330 specimens were caught (65% S. ingentis; 35% S. penicillata) in the depth range from 124 to 338 m. Sex ratio (F:M) was 1.0:1.6 for both species; weight and length relationships (both sexes) showed an isometric growth for S. ingentis and positive allometric growth for S. penicillata. Growth parameters and longevity values were moderate (1.71 and 1.81 years) with age at first maturity around six months for both species. The recruitment pattern showed continuous periods all year long, with a notable peak from November to May. Average natural mortality was 2.47 for S. ingentis and 2.35 for S. penicillata. Distribution and population dynamics information reported in this study for these two shrimp species should be considered as base knowledge in subsequent studies on fisheries management in the Gulf of California.
