Maturity and spawning period of Thrissocles purava (Ham.) as determined by ova-diameter measurements

The peak period of occurrence of Thrissocles purava (Ham.) in Bombay waters is in two seasons, namely February-April and August-October. The mature, spent and maturing fish are caught in inshore waters in these periods. The post-larval forms are also encountered in the plankton samples taken in these months. During the remaining months a few young, immature specimens are available in small numbers. The range of diameters of immature, maturing and mature ova is from 0.08 mm. to 0.44 mm.; 0.45 mm. to 0.76 mm. and 0.92 mm. to 1.26 mm. respectively. The mature ovaries of this species are found to contain only two groups of ova, namely mature and immature. The spawning season, as determined by the ova diameter measurements and the structure of the mature ovary, is found to be the same as the peak period of occurrence of this species in inshore waters. Relatively high percentages of mature and spent females during this period further supports the view that the species visits the Bombay shores mainly for spawning. The spawning period for individual fish is of a short duration and there is only one spawning a season. The minimum period required for the rematuration of the spent ovaries is about six months. The size at first maturity is found to be about 170 mm

Advancements in Animal Physiotherapy Bridging The Gap for Optimal Rehabilitation: A Scoping Review

Animal physiotherapy, a rapidly evolving field, plays a pivotal role in the rehabilitation and well-being of diverse animal species. This review article provides an in-depth exploration of the latest advancements, methodologies, and applications in animal physiotherapy. By combining insights from veterinary medicine, biomechanics, and physiotherapy, this interdisciplinary approach aims to enhance the understanding and practice of rehabilitation for animals

Studies on the maturation and spawning of the Indian whiting (Sillago Sihama Forskal) from karwar waters

1. A study of maturity and spawnings ofSillago sihama based on the detailed examination of 500 specimens of fish and their ovaries and also on casual observations of over a thousand females has been attempted in this paper. Preliminary observations on the condition of testes have also been made from 135 specimens. 2. The female fish have been classified as Immature, Maturing, Mature and Spent, with reference to the condition of their ovaries. The mature ovum contains a single oil globule generally measuring between 0.13 mm. and 0.15 mm. in diameter. 3. A study of the maturation cycle brought out three phases in the life of the fish: (a) Period of active maturation .. April to July. (b) Spawning Period .. August to October (c) Resting Period ..November to (following) March. 4. The spawning period in S. sihama is of short duration and spawning takes place only once during the season. 5. The size of the femaleSillago at first maturity has been approximately fixed at 235 mm. in total length. The females were found to attain a maximum size of 354 mm. in total length. 6. The smallest male specimen with 'mature' testes measured 224 mm. The males attain a relatively smaller size, the maximum size noted being 273 mm. 7. The number of mature eggs liberated in a single spawning has been found to vary from 16,682 to 166,130 in sizes of fish ranging between 184 mm. and 340 mm. in total length

Observation on the breeding activity of the shore barnacle chthamalus malayensis pilsbry in Bombay harbor

A prerequisite for rearing larval stages of barnacles which form an important group amongst the fouling organisms is adequate knowledge of the breeding habits and the time and duration of their reproductive phase. Such knowledge is also useful for assessing the results of the field toxicity tests. The present paper gives an account of the breeding behaviour of the shore barnacle, Chthamalus malayensis, which is found in great abundance along the Bombay coast. If the breeding behaviour of Ch. malayensis reported in the paper represents that of other barnacles in Bombay harbor, the seasonal variations in barnacle settlement reported by other workers can be understood
